I would like some inputs on which Axiom speakers would be best for my dedicated theater room. Primarily the speakers will be for home theater.

Should I go with the Epic 60.500 and save some money or go all out with the Epic 80.600?

It is isolated from sound by a room-in-room contruction, spec'd at 60dB attenuation. The room itself is about 2000 ft^3 in size.

I plan to use a Yamaha 2700 to power the speakers, but I haven't purchased it yet.

I plan to use the VP150 for center channel, and QS8 for sides and back, but I just can't pick the mains and subwoofer. Do I need the M60 or M80 and the EP500 or EP600?

I value my hearing so will not be cranking the volume up excessivily, the sound isolation is so I don't disturb the neighbors or sleeping kids when I watch movies.
