    I’m in no way an audiophile. But this subwoofer replaced an old Sony that had failed. The sound is clear and strong. Great purchase.

    This was a perfect upgrade from my old sub. My only complaint is that there is not easily adjustable volume on this sub. Puts out a lot of power for sure and really great audio.
