I am thinking of purchasing the above 7.1 Epic Grandmaster in-wall/on-wall system. Can anyone provide feedback as to its performance for TV, movies, and music? What kind of sound quality can I expect for the price? It will be used in a family room that is 19X22X9 and driven by a Pioneer Elite 82TXS. Also, I am thinking of getting a SVS PB-12 NSD/2 instead of the Axiom 500 sub that comes with the system. Your advice is appreciated.
