We have a moderately good surround system setup, with a Denon receiver and Boston Acoustic cube speakers (7.1 channel) in a large family room (26'x20'x10'ceiling & carpet) and the subwoofer fills the room with quality sound.

I had to downsize from an awesome 7.3 setup to a bedroom setup

Easy setup and the sound is great.

In short, it's more than capable for someone looking for a nice way to boost their home-audio setup for a relatively low cost

Easy setup good cross-over range
