I see I say. So in a big enough room 8 M50's would do a smashing job as surrounds eh?
Yes they would.
Did you actually mean 2 distinct sets of side surround channels, in addition to the rear/back surrounds? Just curious if you or anyone else knows which receiver(s) has it?
I would imagine that in a BIG enough room, two sets of QS8's for side surrounds could sound amazing, as long as they are far enough apart from each other.
My 3808 has 2 sets of surrounds run off the main side signals, they are not distinct as they run off the same amp, but the second/third zones can be configured for side or rear channels as well as seperate zones, IIRC.
