I have two matching subs, and I have found it difficult to get really useful info on how to set them up. Dual subs should work well for music and for movies. I run mine in stereo. I have been playing with advice written on the RANE website on how to set things up [see the manual for the AC 22B crossover - it has timing (phase) and level setting instructions]. Their focus is more for setting up sepatate speaker cabinets for live performances, but the same problems exsist in our homes. Check it out to see if it helps.
As for two different subs...I am not so sure that would be great for music. Not that it would be bad, but I just don't know. For movies though, I always thought two were better than one to help get an even response from multiple listening locations once they are set up correctly.
