Here is my dilemma. I have a limited budget to purchase speakers for my new home theater room. My HT room has been professionally designed by an acoustician for balanced freq. response (no issues there). It is roughly 2100 cu ft. in size. My question is do I get the EP 350 with larger mains and center channel or do I sacrifice them for smaller ones and go for the EP 500 sub? Any thoughts or advice from owners would be greatly appreciated.
