I have a pair of BP7002 300 watt powered sub each for front speakers. I have a pair of BP7006 300 watt powered sub for rear speakers. I have a Super Cube #1 1500 watt for a powered sub and a CLR 2500 150watt powered sub for a center channel speaker. I have spent thousands on Polk, Pioneer, Yamaha and Harmon Karden speaker systems. Nothing has come close to the sound and clarity of the Definitive Tech speakers. When the Terex walks across the screen in Jurassic Park the water in my drinking glass ripples and the volume is low enough that you can carry on a comfortable conversation. The sound is so real that you will think the Terex is after you. Do yourself a favor and purchase the DevTech speaker systems and leave the other speakers in the store for those that are unwilling to read the reviews. If I had it to do over, and it would have been less expensive, to have purchased the DevTech speakers the first time rather than purchase the other brands.
