I have a Pioneer 2011, currently paired with some unmatched speakers (B&W CM2 stands at L/R, and Canton satellites elsewhere). Not optimal setup, but I can't afford buying more speakers at the moment. :/ Now the magic MCACC of the pio 2011 is compensating for the difference in sound in the various channels, and it is doing pretty well. However, it keeps setting my front speakers as 'large'. The B&W is not exactly large, so I'd like them to be small to redirect the bass to my sub. The manual vaguely suggests that it should be possible between the first round of noise and the second, but I can't change speaker size there. Of course, I can go in and change the speaker size afterwards, but do I violate the MCACC then? Wouldn't it be more precise if it knew about how I like my speakers to be sized from the beginning? Also, I don't understand the 'PLUS' setting of the subwoofer - does it mean that I can set my fronts to Large, and get signals below the cutoff frequency _both_ to my fronts and to my sub? It's a bit time consuming to experiment, so I was just wondering if anyone out there has any ideas or suggestions.. I'd really like to setup things so I can get both multichannel and good stereo sound.
