Been researching, caught the buzz on Axiom... here is my issue. I live in an 1800sq ft. loft, the main space is 25ft long by 40ft wide. with 14 ft ceilings. I have good placement of the main seating area in the center, using a HK AVR 235 with Bose 15 now with a DLP projector facing the the more shallow direction. I can't afford the Epic 80 system... so trying to put lesser package together... will hopefully add an SVS sub later. What is my realistic minimum for this kind of room? Plan to use it for both HT and rockin-out loft parties. Will I need to upgrade my receiver to drive Axioms?
