Starting us off on our review is the BOSS Audio CXX8. I have to say, if you’re really out to get the best 8-inch subwoofers, this one might just be what you’re looking for. Let’s take a look at what it packs under the hood, shall we?

The material construction.

Being one of the things that dictate how good the bass from your subwoofer will be, it’s important that you pay attention to both the cone and the surround on your sub.

For the cone, you’ll be getting a polypropylene cone. This is recommended for use in a subwoofer owing to the fact that it is both lightweight and rigid. This, in turn, gives it a high level of sensitivity to the motion of the voice coil which delivers both a loud and clear bass.

As for the surround, you'll be getting a rubber surround which is renowned for its high level of flexibility and more so, it does stand up quite well to extreme temperatures as well as moisture.

A 2-inch aluminum voice coil

When it comes to handling high levels of power, an aluminum voice coil might just do the trick considering it will stand up quite well to high temperatures. With this on the BOSS Audio CXX8, you’ll be able to play a loud, a low and a clear bass without worrying about damaging it.

PROS

  • 1
    Comes with a polypropylene- both lightweight and rigid for the best bass output
  • 2

The voice coil is a dual 2-inch aluminum coil which can be wired up differently to deliver an even better bass. Also, the fact that its aluminum allows it to tolerate high-temperature ratings.

A foam surround & a polypropylene cone

Though it’s not really the best, having a foam surround is beneficial provided you don’t expose it to moisture.

All in all, a foam surround is preferred to any other due to the capability of retaining its original state for quite a long time. It’s also fairly flexible and has got a large surface area which allows it to give out more bass

39Hz resonating frequency.

This simply makes the Planet Audio AC8D suitable for the reproduction of lower frequencies which in this case is what we want. Anything higher than this would’ve compromised on the bass quality which is yet another reason you should go for the Planet Audio AC8D.

85dB sensitivity.
