Best 15 Inch Car Subwoofers Reviews

If you’re a serious basshead and you’d like to feel that intense, bone-shaking impact of bass hitting your chest, then there’s no substitute for a bigger subwoofer.

Car subwoofers come in a wide variety of types and sizes (ranging from 8 to 18 inch). Undoubtedly, larger subs can handle a ton of power and deliver deep pounding bass that you can feel as much as you hear. For the purpose of this post, we’ll be reviewing some of the best 15 inch subwoofers on the market.

15 inch subwoofes can produce lower frequencies better than small subwoofers thanks to their larger cone area. They can also easily tackle long resonant bass notes making them a top choice for serious bassheads. The downside, however, is that because of the cone size and weight, it is difficult for the magnet to slow the cone down, resulting in boomy bass but relatively poor sound quality when compared to smaller subs.

This is a general rule of thumb because the material that the cone is made of and the enclosure type also play a major role in the performance of a subwoofer as well.

That being said, if you’re more into SPL and volume than sound quality, then a 15″ inch subwoofer is for you. Otherwise, consider a small 12″ or 10″ subwoofer.
