I am building a new house and Because of space limitations I cannot use the bp2000's. Therefore I have decided to go with the PowerMonitor 900's for Front L & R and CLR 2300 or 2500 for center. I will use them for Movies 70%/Music 30%. Will have a 65" Mits Diamond with Sony ES Reciever. Two questions: 1. I want to add an SVS sub to handle LFE signals for Movies and I was wondering if that would make too much base (esp for Music)? 2. I am setting up a 7.1 system with wiring in place already and wanted to use 2 BPX on sides but I am concerned about bipolars used for the two in the back. Aren't the backs supposed to be unidirectional for DTS ES?? Thanks in advance!!!!!!!!
