1. JBL CS1224 Subwoofer

31WjVHzdlbL. SL500

Are you looking for an affordable and powerful upgrade to your sound system? The JBL CS1224 can prove to be a fantastic choice for your car. For this price, you get not one but two subwoofers. Yes, the JBL CS1224 comes in pairs!

The two free air subwoofers will give you unmatchable bass. We aren’t talking about any ordinary sound. It won’t be just one of those loud and blurry sounds. The JBL CS1224 promises you a clear, crisp, and deep bass. How am I so sure about this? Well, the JBL CS1224 has a power rating of 2000 watts max and 250 watts RMS. This is some serious power and bass we’re talking about here.

To give you a wide bass range, the JBL CS1224 has a frequency response range of 35hz-200hz. So you have a wide bass range to choose from. Oh wait, the JBL CS1224 performs great at lower power levels as well! The sensitivity is at 90 decibels. So I guess we have cleared any doubts you might have about the quality of the sound. Needless to say, the performance is going to be splendid.

For the build of the free subwoofer cone, polypropylene is used, which makes it pretty lightweight. No one wants all that extra weight on their car trunk! Also, this polypropylene enhances the overall efficiency of these free air subwoofers. For the surroundings, good quality rubber has been used. Unlike other free air subwoofers that use linear spiders, the JBL CS1214 uses a progressive spider. A benefit of this is that this offers much better controls than the linear spider.

JBL offers a one-year warranty for the JBL CS1224 to make your purchase more reliable. But if you want to get the complete powerful feel of this subwoofer, you might want to get an enclosure for it. But all in all, it is an excellent purchase, which will give you a distortion-free output and quality bass.

Pros
  • Affordable
  • Quality bass
  • High power
  • Less distortion
  • Lightweight
Cons
  • Better with enclosure

For an affordable price, you can get these amazing free air subwoofers and enjoy a clear sound full of bass. Definitely worth a buy.

41Fb8T0K5DL. SL500

Another high performance and good quality sub air woofer would be the Infinity Reference REF1200S. This isn’t any ordinary woofer that just gives a loud sound. When you install it and listen to the first song on this free air subwoofer, you are bound to feel the rhythm right away thanks to the phenomenal bass and clear sound output.

The Infinity Reference REF1200S comes in a neat package. The package contains the one subwoofer, an instruction manual to get you started, and also a technical datasheet. You can select your own impedance using this free air subwoofer.

While it may not look too big and not weigh much, that does not mean it isn’t a fantastic subwoofer! In fact, the low weight can be a blessing as a lot of weight on your trunk can be pretty troublesome. The design is very basic and low profile. The Infinity Reference REF1200S was designed especially for small cars and tight spaces. So you can easily fit this in there. If you plan on placing it in an enclosure, it will fit almost everywhere.

If you’re worried about reliability, don’t! Infinity is a company that knows your struggles. Every product is first tested before coming out into the market. These are tested by running them on their highest power for long periods of time, by shaking them and attempting to break them, by freezing them and what not!

All this is done to make sure your purchase is durable and trustworthy. It’s going to be a purchase to last for a lifetime!

The propylene cone and rubber surroundings make the Infinity Reference REF1200S a lightweight free air subwoofer. None of the materials are particularly heavy. The sound isn’t perfect, but it’s still pretty great. If you want the complete feel, try putting it in a larger trunk. This way, the sound will be able to move freely, giving a more clear impact.

You can select impedances between 2 and 4 ohms. The frequency response is 27-257 Hz, with a sensitivity level of 92 decibels. And infinity offers a one year warranty to back you too! Certainly, a good buy, if you ask me.
