Still waiting to hear from Sony to see if they tell me what the internal crossover freqs for my receiver running in Small Speaker mode. A knowledgeable friend of mine who got the same receiver used didn't know what the crossover was, but said that if he had to guess it would be 80Hz. "Industry Standard?" Let's say for giggles that it turns out to be 150Hz, whould I want to consider running M22's and QS4's as 'Large' speakers and get the full range of freqs? The receiver does have a sub out, so I assume that even if you choose 'Large' speakers the sub still has to get low frequency info while playing in multichannel. However, would that be putting too much of a strain on the M22's. I don't see how it would be any different than running the M22's in 2-channel stereo. Help me out here.
