  • This subwoofer is so easy to install. It also delivers some great bass and is more than enough from what I have expected from this sub.

  • Highly recommended for small spaces. Its a 250 Watt sub and I’ve connected on a 500 watt amp so I don’t push the volume too much but the loudness is still there. I just wondered how can a shallow sub like this one can be able to deliver that much volume

  • Great sub. Less footprint with this shallow sub. But even with how it is, it still sounds pretty great. Great bang for the buck
