I've managed to achieve M5 holosonic projection and pristine bass in my friend's living room. The holosonic projection is equivalent to what I was able to achieve with the M5s in my basement. It sounds like the M5s are projecting images in the interstitial space that exists between their backs and the front wall 4 feet behind them.

The M5s are almost a third of the way into the room and so is her couch. When she came into the room, she let out a big "What the cluck did you do to my living room?" So I says in my soothing man-voice, "I welcome you to listen before passing judgment." When she finished listening, I said I'd put it all back and she gave me a dirty look. No way! Once you hear it, you can't go back!
