Speakers are fantastic technological innovations that have had a significant influence on our culture. Nonetheless, they are incredibly straightforward machines at their core.

It’s simple to feel like you’re staring at a black box when you examine a piece of technology like a speaker and wonder how speakers work.

What is concealed within them? It is somewhat true a lot of the time. Yet if you can master just one or two fundamental ideas, you’d be shocked at how far you can go.

The fundamental relationship between electricity and magnetism is one of the ideas that must be grasped to comprehend how something like a speaker functions. I’ll describe how they work in this in-depth article using precise explanations.

The History of Speaker

how speaker work

In fact, early telephone designs by Johan Philipp Reis from 1861 contain the first speakers. These were improved upon in later decades by people like Thomas Edison, Ernst Siemens, and Alexander Graham Bell.

But, the now-ubiquitous moving coil technology didn’t fully take off until the early 20th century. Oliver Lodge first created the concept in 1898, and Edward W. Kellogg and Chester W. Rice successfully patented it in 1925, establishing the fundamental design for practically all speakers in use today.

When producers worked to enhance features like overall power and frequency response in the setting of theaters and huge PA systems, things started to really take off in the 1930s.

Systems with several drivers for various frequency ranges, design uniformity, and better materials for components like the driver cone, magnet, and enclosure were all developments in the 20th century.

How Do Speakers Work?

Here is a detailed explanation of how speakers work:

1) The musical waveform’s representational output voltage starts to rise. From the positive side to the negative side of the speaker’s voice coil, an electrical current begins to flow.

2) The voice coil is surrounded by a magnetic field that has the same polarity as the permanent magnet fastened to the speaker frame. Keep in mind that magnetic fields that are opposite each other repel one another.

3) As the cone/diaphragm moves forward, air pressure is generated, which produces sound.

4) The current increases, the magnetic field strength of the voice coil grows, and the electrical signal voltage increase toward the peak of the sine wave in the musical signal.

5) The cone is further pushed out as a result.

6) After reaching its peak output point, the signal starts to decline. The cone starts to move toward its off (zero voltage) point as the current starts to decrease as well.

7) The cone returns to its initial position when the signal approaches zero (also known as the “zero voltage crossover threshold”).

8) Once the voltage shifts to the negative side, the electrical signal starts to reverse. A magnetic field with a reversed polarity is produced when current travels from the negative voice coil side to the positive.

9) The magnetic field of the voice coil now opposes the permanent magnet attracting it, and the cone starts to move from front to back (instead of the original rear to front).

10) The cone rotates backward as the signal continues, producing the opposite of the sound waves produced by air movement.

11) As soon as the stereo or amplifier output voltage reaches zero, the next audio signal starts playing and the cycle repeats itself.

In a sense, speakers are merely a form of electric motor that converts an electrical signal into a mechanical output—moving air to produce sound—by using it as power.

What’s Within A Speaker?

how do speaker work

The following components, which are found in most speakers, work together to produce sound:

Permanent Magnet – To enable movement, a magnet is employed to provide a constant magnetic field around the voice coil.

Voice Coil and Bobbin – A cylindrical tube is known as the bobbin is fastened to the cone’s base. The voice coil is an extremely long and tightly wrapped wire coil that receives electricity from an amplifier’s musical output, which travels through it to produce a magnetic field.

Spider or Suspension – The voice coil bobbin assembly is supported by the thin, wavy-shaped woven material known as the spider, which also aids in pushing the cone back into position when it shifts.

Cone & Dust Cap – This rigid cone-shaped material is moved by the voice coil and magnet working together to move air and produce sound. To keep dirt and dust out of the opening in the center, a thin piece of material called the dust cap is placed over it.

Speaker Basket – The basket, which the speaker pieces attach to and which maintains alignment, is a cast metal or stamped metal frame. Moreover, it offers a method of mounting the speaker assembly to a box.

Speaker Terminals & Braided Wire – The speaker wire is connected to the speaker by speaker terminals, which are metal tabs or connectors. They use a flexible braided wire that moves with the cone to connect to the voice coil.

Surround – The material holding the top edge of the cone to the basket is flexible and strong, typically rubber or a sort of foam.

Why are Speakers Fitted in Boxes?

Speakers are fitted in boxes for a variety of reasons. Firstly, the box helps to reduce any sound waves emitted from the back of the driver, which could interfere with the sound being produced from the front. This is known as ‘acoustic loading’ and it helps to make sure that all of the sounds are coming from one direction.

Secondly, boxes help to increase the bass response by trapping low frequencies inside them, so they can be heard more clearly. Finally, boxes also act as an amplifier for low frequencies by creating an internal resonance cavity that amplifies these sounds. This helps to create a fuller, richer sound overall.

Why are there Holes in Some Speakers?

how does speaker work

Many speaker boxes include circular holes or slots, usually on the front or back, as you may have seen. You may recognize a bass reflex enclosure by the ports or vents you can see in it.

Similar to how a note is produced when air is blown over an open bottle of beer, a bass reflex enclosure operates similarly. Because the volume of air inside the bottle changes as the number of liquids changes, the note also changes.

The note would also change if you were able to expand the bottle’s glass neck. It is a resonant system that can be tuned by changing the enclosure volume or the port dimensions.

If adjusted properly, this extends the system’s bass performance by producing a resonance just below the point at which the loudspeaker response would typically roll off. The port tuning must be calculated for the exact driver in the specific enclosure in order for this to function properly.

Even though the cone diameter of the new driver is the same, the box and port tuning will no longer be suitable, and the sound quality will suffer.

The basic operation of passive radiator loudspeakers is the same, but the bass resonance is produced by the enclosed air volume and a mass-loaded, unpowered speaker cone.

Why are Magnets Found in Speakers?

Electrical current is used by all speakers and amplifiers to produce sound. Magnetic fields are created when electrical current undergoes a transformation. Built-in magnets are used to create a magnetic field that opposes the magnetic field of the electrical current, causing the speaker’s cone to shake. We perceive sound because vibrations are produced when two magnetic fields that are opposed to one another repel one another.

What Increases a Speaker’s Volume?

The volume of a speaker depends on how much power is passed through it when it is in use. The power going through any amplifiers you have will also increase the volume. Its loudness is further affected by additional elements like speaker size, insulation, and speaker cone reflex.

Hence, if you want to increase the volume of your speaker, make sure it is big, has a compact, tight cone, and has sufficient insulation. It should also have the appropriate wattage.

How Often Do Speakers Vibrate?

The design of the audio system, specifically the audio signal frequencies present in the audio drivers, affects the frequency or rate of a speaker’s vibration. Most speakers can vibrate within an audible range with reduced bandwidth, and the sound range typically ranges from 20Hz to 20 kHz.

Final Thought

Speakers are a vital part of any audio system and understanding how do speakers work is key to getting the most out of them. From the basics of how speakers take an electrical signal and transform it into sound waves, to the importance of power, quality materials, and tuning, knowing these components can help you make the best choice when buying speakers. With this knowledge in hand, you’ll be able to find the perfect speaker system for your needs and get great sound from your audio setup. Whether you’re upgrading your car’s audio or want to fill your home with sound, understanding how speakers work is essential for enjoying great audio quality.

Is your speaker distorting sound on high volumes? Are you tired of the crackling sound ruining your immersion while watching a movie or listening to a song? Well, we are going to show you a few ways through which you can fix that and enhance your listening experience.

How to Fix Speaker Distortion

There are several reasons why a speaker might start distorting audio at a high volume, like, the speaker being pushed beyond its limit, problems in its wiring, dust blockages, and so on. And this audio distortion does not only occur in stereos and other sorts of external speakers, but the speakers of your phones, cars, and even laptops are prone to it. Which is why we are going to show you how to fix speaker distortion in each of these cases.

How to Fix Speaker Distortion in Cars

If you’ve just bought a new car or a new sound system for it, then sometimes you might face some speaker distortion. This is because you are not familiar with the speaker’s limit, and so playing audio beyond the limit might cause distortion. Also, other components of the car like the signal lights, air conditioning, or wipers might be interfering with the audio of the speakers.

When dealing with the former problem, you need to turn your speakers down to 75% of the volume, which will ensure loud yet clear music. But even if the sound is still distorted, you need to make sure that the other components of the car are not interfering with the speakers. To do this, you need to first turn off all of them and only have your speaker on. If the noise is clear, then slowly turn the other components back on one by one. Through this, you can locate the exact component that is causing the interference.

Another way to prevent distortion is to avoid any sort of bass boosted music. This is because there are many cheap ways to add bass to music through various free programs. And so if the bass is added in the music unprofessionally, it will certainly cause a lot of distortion in your speakers at extreme volumes. If you still want to play the bass boosted audio, then to prevent distortion, you can simply turn down the bass in the settings of your audio player. The preferred setting for no distortion is +10 bass and -5 treble.

There are other ways through which you can prevent speaker distortion even at quite high volumes, like using high pass filters. These are usually the best option if the sound distortion is from the speakers installed in the door of your cars. This is because these filters let high-frequency signals pass through while making it difficult for low-frequency ones to pass. This basically means that these filters will block out the bass in the audio that is causing the distortion.

Also, you can eliminate audio distortion from your speakers by installing car amplifiers. This is because  they supply a higher power output inside the speakers that results in a louder sound without any sort of distortion. And so, through amplifiers, you are able to enjoy clear music at quite high volumes.

One of the reasons why distortion occurs in car speakers is because cars do not exactly have the best acoustics. This is because there are a lot of elements inside cars that are sure to interfere with the way the audio is heard by you. These elements include glass windows and windshields, as well as the plastic interior that reflects the sound produced by the speakers. Also, the foam padding of the seats and the carpets on the floor have the ability to absorb sounds.

Therefore you need to install an equalizer in your car audio system to minimize all these factors affecting your audio and give you a clear sound. Equalizers also let you control the tone as well as the bass of your audio. Through which you are able to have the perfect settings for your audio for your optimum music listening experience.

How to Fix Speaker Distortion in Cell Phones

Over time many of us have experienced the audio from the speakers of our phone getting distorted. Usually, there are two reasons why this happens, the first is due to problems in the hardware, and the second is because of problems in the software. When it comes to the hardware, the reasons are mainly water damage and dust or debris blockage in the speaker.

Water damage to your phone can not only occur through accidentally dropping your phone in water but also through sweat and humidity. If your cell phone speakers have suffered water damage, then the first thing you need to do is turn it off and take out the battery if possible. Next, dry your phone using a dry cloth or tissue paper, or place it in rice. Once you are sure that your phone has dried completely, turn it on and check the audio of your speakers.

To locate dust or debris blockage of your speaker, you need to closely examine the speaker net of your phone. If you are able to see the blockages, then using a thin tool, like a needle, gently try to scoop out the debris from the speaker net. Once that is done, play an audio file on your phone to check if the distortion has subsided.

When it comes to speaker distortion due to the software, like the interference of third-party apps, etc, then the process to fix it becomes a little more complicated. This is due to the different operating systems for Apple and Android, because of which the fix for one might not work for the other. And so, we are going to show you what you can do to fix the audio distortion for each.

For Android phones, like Samsung, you need to restart your phone in Safe Mode. The exact method might vary for various android devices, due to which you might have to look up the method for your model. But one of the ways you can do this is by holding down the Power off option after pressing the power button and then selecting the Reboot to Safe Mode option. This will reboot your phone without restarting any third-party ads. And so there would not be any interference with your speakers.

If this does not work, then you might have to do a Hard or a Factory reset. Again this method is different for different android models, which is why you might have to look up the proper way to do it on your phone. It basically removes all the data from your phone and reverts it back to the way it was when you bought it. And so this also cleans up the software from any bugs or viruses that might be causing the speaker distortion. However, you have to make sure to create a backup for your data beforehand.

For IOS, if there is a problem in the software causing speaker distortion, then you need to restore your iPhone. This is basically the same as the Hard reset of the Android phones as it wipes your phone from all of its data and restores it back to factory settings. This is why you need to back up all of your data before restoring it so that you don’t lose it.

If the speaker distortion of your phone is still there after trying all these methods, then the speakers might be damaged beyond your ability to repair. And so the only way you would be able to hear clear audio is through taking your phone to a professional and getting the speakers fixed or replaced.

How to Fix Audio Distortion in External Speakers

The main purpose of external speakers is to produce loud and clear audio for your entertainment, which is why it is all the more disappointing when there is audio distortion. Therefore, to save yourself from the irritating static noise from your speakers, there are a few methods that you can try before spending money on a professional to take a look at them.

First of all, you need to make sure that you know the limit of your speakers. If you try to push beyond those limits, then the sound distortion is inevitable. For this, you need to check the maximum volume that your speakers are able to produce without distortion and try to stick to that volume limit. The best option for this is around 75% of the total volume of the speaker.

If the audio is still distorted despite being 75% or less, then you need to make sure that the connection of your speaker to the audio system is fine. In the case of non-wireless speakers, you need to check if they are plugged into the system properly and the pin connection is not loose, and that the wire connecting the two devices is not damaged. In the case of wireless speakers, make sure that the speaker is connected only to your device and no other device. Otherwise, there might be interference that might cause distortion.

If the connection is fine, but the speaker is still producing distorted audio, then there might be a problem with the audio system that is connected to the speaker. Try to adjust the different sound modes on the system to find the most compatible one that produces the least distortion. You should also try to remove the audio device and connect your speaker to a new one to check if the source itself is not faulty.

If all this fails, you need to check your speakers for any sort of damage in the wiring or the circuitry and try replacing any old or worn-out wires. You can find the replacements either online or in a hardware store for a cheap price. If this still does not fix the audio of your speakers, then you might have to take your speakers to get fixed by a professional.

How to Fix Speaker Distortion in Laptops

Laptop speakers are quite susceptible to audio distortion due to the speakers being small and not usually good quality. And so on really high volumes, audio with a lot of base is bound to produce crackling and scratchy noises. Therefore the first step to fix the audio distortion is to lower the volume of your laptop. But if this step doesn’t work or if your laptop has recently started giving out distorted audio, then there are a few things that you can do in order to fix this problem.

The first method through which you can fix the audio is by troubleshooting the speakers of your laptops. For Windows, you need to open up the troubleshoot settings and select the ‘playing audio’ option. Then click on ‘Run the troubleshooter’ and follow the instructions given to you. Or you can right-click the speaker on your taskbar and select the option labeled ‘troubleshoot sound problems’. And so your laptop will find out the problem with your speakers.

For Mac, on the other hand, you need to restart your laptop, and while it is restarting, you need to hold down the ‘d’ key. This will open the Apple Diagnostic, showing you a progress bar as your laptop looks for any problems in the system. After that is done, it will inform you of any problems that your speakers may have. From here, you can either proceed with restarting your computer or turn it off.

You can also adjust the sound format of your laptop to one that produces the least distortion. For Windows, you need to right-click on the speaker option on your taskbar and select ‘Open Volume mixer’. Then you need to click on ‘Speakers’, which will open up speaker properties. Next, click on the ‘Advanced’ option on the top and change the default sound format from 16 bit, 48000 Hz to 16 bit 44100. Then click ‘Apply’, and your sound distortion would be considerably lower than before.

To do this on a Mac, first of all, you need to go to the Apple menu and select System preferences. After that, you need to click on ‘Sound’ and from the options, select the equalizer. When that is done, you will have two options through which you can adjust the audio; you can either choose a preset option or change the separate elements of your speakers using the sliders.


What causes speaker distortion?

There are many reasons for speaker distortion, but the most common one is by pushing the audio of the speaker beyond its limit.

How to fix speaker distortion in mobile phones?

You can fix speaker distortion in mobile phones by physically cleaning the dust and debris out of the speaker net or rebooting your phone.

Wrapping up

Do you face problems in tuning the subwoofer? A small mistake in setting can ruin the entire system. That is why you cannot play the sounds that are pleasant. Moreover, they do not produce tones at reasonable listening volumes over the entirety.

How to Tune the Subwoofer

Subwoofers are perfect for a variety of purposes from raging parties to casual drives. You can use it either for orchestral music, rock and roll, or for low-frequency effects explosions in blockbuster movies. They are a well-balanced speaker and provide less bass distortion.

Set the Gain to Clear away Deformity

Sometimes distortion occurs due to excessive clipping which leads to poor sound quality and damage of speakers. That is why tuning processes to set the input sensitivity or gain on the amplifiers, is important to get the optimum performance from the amplifier without extreme clip.

First of all, disconnect the speaker wires from the amplifier’s outputs. Make sure that any processing from the source unit and amp is turned off to confirm that bass and treble on the head unit are set to zero. Then completely turn down the feed-in responsiveness on the amplifier. If the amplifying device has either a low level or high-level sensitivity then set it to the low position.

Set its volume to three-quarters of full volume to allow the reasonable gain overlap with a moderate excerpting at full volume. Use the recommended voltage chart to determine the proper output voltage for the loudspeaker based on its application. After that, play the one-kilohertz sine wave at 3-4th capacity. Then place the digital voltmeter to read AC voltage and connect it to the announcer outputs on the amplifier.

Then boost the left front positive and the right front negative as well as on the rear, the west side positive, and rear right negative outputs. For a traditional four-channel, beat the positive and negative gain from each avenue individually. Then slowly increase the input sensitivity of the amplifier until reaching the approved voltage. Now the loudspeaker has been set to its maximum unclipped output levels. Again reconnect the speaker to listen to the system with music at a moderate level.

This is to listen and check if one amplifier is overpowering the other, such as the door speakers being louder than the subwoofer. If one of the amplifiers is playing too loudly, turn down the input sensitivity of that amplifier until both amplifiers are blending nicely together. This defeats the purpose of too much clipping into the system. Finally, the gain on the amplifiers is properly set to reduce the potential for excess clipping to minimize the falsification for improving reliability.

Set the Subsonic Filter to Remove low Frequency

It is needed to block the lowest audible frequencies. However, always set the subsonic filter normally around half note below the tuning. So, any beat below the frequency you pick creates noise. If it is set to 31 hertz. That is why frequencies lower than that will be drastically reduced coming out of the amp because the setting is not designed to play that low number. It allows a clean signal.

Adjust the Bass Boost

A lot of amateurs use it to make their bass louder. However, do not use it across a broad spectrum because it causes some malformation. That is why it damages your subwoofers. So, use it carefully. If you set the frequency 60 hertz and then you turn your bass boost up to 60 halfway it creates a peak right at around 60 Hz. So anytime when you play music at 60hz bass beat is going to be super extenuated loud, and it is unproportional. At higher volume, it sends unclean waves, which causes a much quicker clip. This is entertainment for everybody because it makes the sound blaring.

Adjust the Frequencies

The LPF (low pass filter) allows the speakers to play the frequencies that you want to play and not run the ones that you do not want on the amplifier. It is adjustable from 30 hertz up to 250 Hz. If the LPF is set at 80 hertz then the subwoofer does not tune anything above that. The setup of the low pass filter depends on the size of the speakers. For example, if LPF is set at 100 then the subwoofers play 100 hertz and below. As you covered the frequency spectrum, you can hear every note of the music that is designed to hear.

An HPF (high pass filter) allows frequencies higher than a certain point to pass. This provides better speaker protection and more efficient usage of your amplifiers. The combination of a high pass and a low pass filter allows frequencies within a certain bandwidth to pass through subsonic filters. If they are mid-bass speakers, then they are not going to reproduce the low frequencies of the subwoofers. So turn on the high pass.

Adjust the Phase Change

The phase is all about polarity if the subwoofers are inverted or regular. It changes the direction in which the speakers are moving. When you alter the phase, you are changing the polarity which changes the direction of the motion of the speaker. If the polarities are hooked up correctly then you can listen to the music without any disturbance.

You can make changes if they are out of phase. For example, if you have one set of speakers going and another one going down, delay half a second in moving above and below. Then start adjusting the phase properly and the proper way to do that is with an oscilloscope to match the sine wave together. This allows your speakers to work together, and not against each other. After all these levels you hear a loud and harmonious sound.

During this tuning process, common mistakes can usually occur. The misstep that can occur is the setting of the subsonic filter too low and the low pass filter too high on your sub and this usually occurs when the installer is trying to squeeze every last drop of output out of the system. But this is reckless and should be avoided as it can likely result in damaged equipment.


Oftentimes when you bring the subwoofers people start to frown and talk about how bad they sound. And absolutely they can sound bad, but when set up correctly, a subwoofer is nothing but a benefit to your system. You can hear your favorite music at high as well as at low volume.

Good quality video and audio can take your screen time to another level. Watching your favorite movie on a big screen with realistic sound effects is truly soothing after a long day. Fortunately, you no longer have to buy a ticket for cinemas to watch movies with full effects. You can build a home theater in your living room and enjoy non-stop screen time with immersive effects. You can invite friends to your home with confidence for a movie night and enjoy the true-to-life movies in the comfort of your own home.

How to Setup Home Theater

Setting up a home theater requires a few things such as best home theater subwoofers. You can watch cinema-like FHD or UHD movies and shows with top-quality sound output having to surround sound effects. Several well-reputed brands sell all the components necessary for setting up a home theater. Let us discuss in detail all the elements you need for building a home theater and in what sequence you have to connect all the components.

List of Key Components for a Home Theater Setup

Projector or TV is the main component that allows you to see the visuals with ultimate clarity. You will require a TV bigger in inches and higher resolution for full mesmeric effects for home theater. Remember we are trying to turn the media system into a mini cinema, so you need a bigger screen. Before looking for a TV or a projector, make sure they are 4k compatible. In that case, you will have bright and vivid visuals on the screen.

Now, if you want to get a projector for your home theater, you need to get a screen to project the light. The screen size of a projector depends on your personal preference. For a projector, you also require a projector mount that will allow for less clutter. If that isn’t possible, you can also allocate space for a projector other than the ceiling to remain safe from movement. You can easily find suitable quality projectors and TVs that are 4k compatible at affordable prices. Some of the well-known brands are LG, Sony, BenQ, Epson, Optoma, etc.

Home Theater Receiver or a Soundbar

The next thing you need for a mini home cinema is a home theater receiver or a soundbar. The decision of which device to buy depends on your personal preference. However, if you are going for a projector, it is better to opt for a receiver as it sounds far better than a soundbar. In case you drop the projector option and choose a TV screen instead, you can always go for a soundbar. Most people choose a home theater receiver over a soundbar for its better sound output and diversity.

If you choose the first option, you need to look at a few things necessary to set up a home theater. Make sure that the receiver comes with HDMI ports that will come in handy during the connectivity. Also, the receiver should be compatible with the 4k content for high-quality visuals. In addition to that, the HDMI ports should also support HDCP so that you see authentic and top-quality content on the screens.


The next main component you will require is the speaker. Speakers have the most contribution in providing full immersive effects and bringing the characters to life. You can have a bad movie or show-watching experience if you go wrong with the speakers. The first thing you need to do is test the speaker before actually buying them. The testing will place you in a better position to buy the ones that fulfill all your expectations.

Now, the next decision to make is what channel do you want for the sound system. The number of speakers you get for your home media system again depends on your personal preference. More speakers will allow for more fidelity and surround sound effects. In addition to that, more than one subwoofer allows for better bass quality. So if you decide to buy a 5.1 channel sound system, you will require 5 speakers and one subwoofer.

The center channel speaker will go just under the screen to make the sound output feel coherent. After that, you need to place the two main speakers on both sides of the screen. The two surround speakers need to be placed at both sides of the listener for maximum surround sound effects. Lastly, it would be best if you placed the subwoofer close to the screen so that you can experience quality low-frequency tunes. You can always opt for 7.1 or 7.2 channels for more real-life-like sound effects.


Now that you have all the components waiting to be connected to start your home theater, you will need HDMI cables to connect all the devices. In addition to that, you will also need a long cord. Moreover, you will require speaker cables to build a connection. It is always recommended to get high gauge wires, most preferably 14 gauge, that provide a stable connection for powerful speakers. It would be best to get a big reel of speaker cable not to run short of it. In addition to that, you also need to make sure you get banana plugs for your speakers for a smooth connection. Lastly, you will need a cable for the subwoofer to connect it to the speakers and the receiver.

Surge Suppressor

When you create all that powerful setup, you also need to protect the electrical connection from power surges or thunderstorm damages. For that matter, you will need a surge protector or power conditioner so that your whole electrical connection stays protected. If you mean to invest in a surge suppressor, make sure you get one with a high joule rating to get good performance.

Media Player

The next thing you need to get for your mini-home theater is the media player. This is only necessary if you want a projector as your video source as most of the projector comes without built-in apps. To make the projectors work, you need a good media player to play certain apps. Make sure the media player you are getting fully supports 4k content.

Remote Controller

The last thing from the components list is the remote controller that adds to the convenience. You would want to get up and control certain features of your home theater while sitting on the couch. It is better to have a universal remote that allows you to control all the components. Owing a universal remote will spare you from the hassle of controlling all the devices with different remotes. Several different brands are selling good quality universal remote controllers at reasonable prices.


Once you have gathered all the essential products required to set up a home theater, then comes the most crucial part. Setting a home theater might test your patience as one missing plug may cause issues in the overall performance. If you mean to install a projector, the first thing you are required to do is allocate a safe place to it. You need to test where it should go best and what measurements of the screen do you want. Make sure that you install the projector in the place where the measurements of the image exactly align with the measurements of the screen.

For the installation, you can either install it to the ceiling with a professional’s help or use raceways to fix the HDMI cord. If you want to place the projector on the tabletop, make sure you find a place where it can stay put. Moreover, you need to make sure you adjust the projector’s settings before installing it to the ceiling. After that, you need to connect these devices to the home theater receivers via HDMI cables.

After that comes the placement of all the speakers and subwoofer. The placement of speakers and subwoofer depends on the measurements of the room you want to build the home theater in. If you are using a soundbar, you should mount it on the wall above the screen or place it just below it. However, if you have purchased multiple speakers, you have to make sure you have placed all the speakers in proper areas.

The center channel comes right under the screen for coherent sound effects. In addition to that, the main speakers should be placed at the sides of the screen. You need to keep at least 6 feet distance between the main speakers. Now, there are different ways to install the surround speakers. You can either mount them on the walls close to the ceiling, or you can mount them on the wall at your ear level. It greatly depends on your personal preferences.

For setting up the subwoofer, you need to check the size of your room. One subwoofer is enough for a small room; however, you can install 2 subwoofers if you have a larger room. You can place the subwoofer between the main speakers or at the corner of the room for perfect sound blending. In addition to that, you can also use a subwoofer crawl method to allocate a place to a subwoofer.

Now that you have done the speaker’s allocation, the next step is plugging them into the receiver. You can use the banana plugs to connect all the speaker cables directly to the receiver. The last thing you want to do is setting up the remote for added convenience. It will allow you to control all the devices from a single remote controller. After you are done with the setup, you can sit back, relax, stream your favorite movie or show and watch it with immersive visuals and sound effects.
