My wife and I wanted to add a subwoofer to the computer sound system in our study. And our available space was very limited. After much research we decided on the Cambridge Audio Minx X301. Now that it is set-up with our Audioengine A5+ speakers we can enjoy a truly amazing listening experience. Adding this very tight and powerful subwoofer enhances these already great speakers. The Crutchfield technical staff, fair pricing and prompt delivery bring me back again and again.
