I want to thank you all for all the great information I've been gathering here!
I realize I probably should have started with the speaker question. Yes, I'm learning!
Anyway, the system I've been quoted and recommended includes Paradigm Studio 10 fronts, CS-60R-30 in ceiling surrounds, a CC-490 center and a Seismic 10 sub.
I know it's hard to know what's best for a certain application without knowing all the variables and that speakers are likely one of the MOST subjective pieces of equipment but I was hoping to get some comments on this setup.
