Quite honestly I have to be careful about balance as it is. What seems appropriate for Tocatta & Fugue for Organ in D Minor by Bach with the bass speakers is way too much for Dave Matthews. One works great and the other one muddies the sound. While I can simply turn the volume down on the Power amp that supplies power to the woofers, I find that two 12's are more than adequate. The power on the woofers is never turned up beyond 11:00, except occasionally for Victor Wooten with Bela Fleck. Booming starts above 12:00.

What an array of woofers in my 12 x 18 room would be like I can't nor do I want to imagine. It would lose lots of aspects of the music itself, and make it un-natural. I went from miniature music with point source speakers, to life size music now. i think that would turn it into music on Steroids like Mr. Hyde from the movie LEAGUE OF EXTRAORDINARY GENTLEMEN.
