I think its going to depend on one's definition of what's acceptable. As you mentioned, when you have 4 or 8 seats, how can you possibly have it sound premium in every seat? There's got to be some compromising somewhere.
After getting the MBM and sub time aligned to each other and aligned to the mains, today I found that other sounds above the sub and MBM range sound slightly distorted. So, I'm back at the drawing board once again. Reverted back to my Velodyne sub, SMS-1 and regular speakers to give myself a break to regroup.
