With my M22 for music soundstage was not as good when crossover at 80 or even at 60. You loose the openness of the soundstage. So for music I switch the crossover off on reciever and set the speakers to large. And set my sub to 55Hz since the M22 goes only down to about 50 hz. For movies I switch my crossover of the receiver at 60 and set the speakers for small. A pain in the butt but it gives both modes the best sound quality. Whats 30 seconds to change settings.
