Summary: I am a huge fan of this sub woofer. It provides more than enough power to satisfy a normal household environment. However, if you're looking to fill a large room with chest-thumping, deep bass I would recommend something larger. Yet, for my home stereo in a 1500 sq ft house it works very well.
Summary: Excellent sound. I have been around professional audio equipment my whole life, and, these are some of the best speakers i have ever owned. The only advice i can give is, you need a high power amp to push them properly.
Summary: I agree with Connie W.; I don't know what the 1st reviewer is talking about. My XLS 12 is hitting like a sledge hammer! Deep hard hitting bass. I ony buy Cerwin Vega speakers and I have never been dissappointed. Maybe the 1st reviewer bought a fake one.
