Sammisra,
I have 3.7's in a 15.5' x 19' room. No problem at all. The strange thing is that they integrate better in the room than my 1.6QR's did. I've been able to take about half the room treatments out of the room. I certainly didn't expect this. The top end is much less aggressive in the 3.7R's. They are really wonderful speakers. Haven't heard the Gallos or Kingsounds.
