Then you're using the term differently then everyone else.

Well, it's certainly true that room effects make this more complicated. My point was merely that since dipole power falls off more repidly with distance, that might be the reason dipole speakers are less sensitive to the room. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=38593 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
