Hmmm. I think that my on-wall M3s sound better than the highly praised (even by me) QS8s for surround duty.
I get nice and fairly deep extension in the audio range compared to the QS8s as well, and they "aren't to shabby."
Just seems a bit baffling, then again, they aren't full sized tower speakers, and are smaller than their bookshelf brothers.
Some popular speakers or ones mentioned in this thread with have the following low end:
M80/100 - 31Hz $954each/$1395each
VP180 - 34Hz $965each
M60 - 40Hz $730each
VP160 - 45Hz $740each
M3 - 60Hz $249each
OW M3 - 70Hz $249each
VP150 - 85Hz $530each
QS8 - 95Hz $340each
QS4 - 100Hz $265each
So the only thing that goes a little deeper for a more full for the same or less money is the regular M3 by 10Hz for the same money. Nothing in the list above costs less per item (I know that comparing a center channel to a surround to a floor-standing to a bookshelf is a bit silly)...
For me, even my receiver noticed that the on-wall M3s could go deeper then my QS8s and it adjusted for it, and I love how full my surround sound is now (from the 25Hz deeper extension).
So I am a bit baffled, but certainly NOT saying that you aren't hearing less "wow" and "pizazz" than you should. I wish that I had some real practical tips for you.
