Main speaker size: Meridian would normally treat 5200s as "large" speakers. A 5200C would normally be treated as "small" to force it to do less work. This is critical given that a centre speaker typically handles 70% of the front duties. The main point here was that you shouldn't be afraid to set a physically big speaker to "small" and use the processor's crossover to re-direct the lowest bass to a sub.
Yes, I have my fronts - larger than 5200's - set to small. With a crossover not set too low they get a lot of "middle-bass" to play anyway. But since Meridian don't think per-speaker crossovers are a good idea all speakers has to be able to handle the delivered bass.
Bass *is* left/right directional due to time differences in the wavefronts hitting the ears. There was some discussion that I missed a bit of where Des said that M usually recommends to its dealers to use chained mono subs rather than stereo left/right subs, but I can't remember the reason why. It might have been because Meridian processors are restricted to eight output channels and that, if you have stereo subs, you can't have a 7.2 setup, only 5.2. Can anyone help me out here? I certainly intend to try a 5.2 setup at some point.

I had a couple of years worth of discussion regarding subs - through John Kotches' Q&A session - with Meridian... I wanted the possibility of the same signal sent to miltiple subs, for instance a 5.3 setup with mixed analogue and digital subs, but Meridian didn't like the concept of sending the same signal to several subs. And now they're recommending chaining mono subs - the solution I had to use (a center/back mono config with the two Velodynes chained as a center sub)...?
