I am building a HT in my new home. My first buy was a SVS PB12 which I love. The room is 14x16 with a 9 1/2 ceiling. I have decided to go with an Ascend package but should I get 4 CBM 170's to go with a CMT 340 center or should I step up and buy the 340 mains. The advantage I am looking for in the 340 mains is the ability to play louder. When I called Ascend they were helpful but it came down to a coin flip in their opinion. If you own Ascends, please chime in. My use will be 50/50 music and HT. Any help would be greatly appreciated.
