My room is 13 W x 25 L
I have my couch situated about 10 feet from the speakers in the middle of the room. The Meta's mange to fill the space with abundance. The BAT amp never runs out of juice and can play louder than I care to listen. I have stuffed the rear ports on the Meta's with a little foam to reduce the backward energy and so far everything sounds pristine and un-muddled.
