    Surprising amount of kick for a smaller unit. Considering a second for a 5.2.4 setup, but one just might be enough on its own.

    All is great. Quality and sound is good for the money. One small improvement will be to have the ability to install bigger screws at the bottom. The sound dumpers are very inadequate and to upgrade it is impossible.

    Kef 10"sub hits pretty hard and fills my 22'×24' den with plenty of bass to compliment my LS 50s. Not quite rap level bass but definitely Acdc rock/roll

    I have another older , bass and I wanted to try 2 to balance everything. It works for me but I definitely do use this to its full capacity. But I am loving the kef brand, clean crisp speakers. I'm done with sound bars, unless I want to just spend $300 for a guest room or something.
