In the current digitalized world, things have taken a different dimension and subwoofers have become more domestically accepted especially for their sonic benefits.

When used appropriately and safely, subwoofers are extremely convenient, effective and long-lasting.

The low-profile 40CWRT122 12” subwoofer performs just like a full-size sub, but without killing all your cargo space. This high-performance CompRT sub stands less than 4″ tall, so your installation options are wide open.

The 40CWRT122 comes equipped with a firm injection-molded polypropylene cone that does not flex or cause any kind of disturbance in the process of cranking the bass.

The rubber surround is highly durable even with heavy usage and is especially designed to give you better excursion (which equals more bass) than other skinny subs.

This sub handles up to 800 watts RMS so make sure you’ve got a solid amp to power it. You can wire the dual voice coils for either 4- or 1-ohm total impedance, giving you more wiring options when setting up your system.

This versatile sub sounds great in sealed or ported enclosures. The CompRT subwoofers works best with a sealed or ported enclosure and 500 watts of recommended power.

What we like about this product?

The best part of the Kicker 40CWRT122 Subwoofer is the fact that it has a constant power handling capacity which can go as high as 500 watts RMS and a big frequency range of 25–500Hz which means that you not only get really high sound levels consistently but also the bass sounds blend seamlessly with the sounds of your other speakers to give you a premium listening experience.

We love the unique one-piece Uniplateconstructionwhich helps to eliminate any erratic magnetic flux between the voice coils that can cause distortions to the sound. It also ensures that the pressure under the suspension is released in a way that ensures that the entire cone moves uniformly to ensure clarity of sound.

The polypropylene cone with its santoprene surround is ultra-rigid which ensures that the bass sounds are clear and accurate.

The above unique design along with the vents ensure that the coils do not get heated during long hours of playing music ensuring longer life for the subwoofer.

The dual 2Ω voice coils offer flexibility to the user to change the load from just 1Ω to 4Ω depending on the users taste by either wiring them in parallel or in series.

The CompR series of subwoofers from Kicker come with Tinsel leads which are woven into the spider which helps reduce the stress to the joints

The entire system is designed to be truly shallow mounted (mounting depth of 5¾inches) which means it can be installed in all cars including compact cars and motorcycle saddlebags.

What we don’t like about this product?

  • It is more expensive than the other 12-inch subwoofers in the market, but it is worth it just for its power handling capacity and quality of build.

And Finally

If you looking for a subwoofer which delivers a powerful punch with a wonderfully clear and accurate bass sounds and you don’t mind spending a little bit extra for it, then the Kicker 40CWRT122 is the one for you.
