Just a quick question on the best way to set up the sub/speakers in my new environment. I have: HK 325 mains=b&w 603 s3 center b&w lcr 60r rear= speakercraft 6.5 inch in ceiling speakers future rear=b&w 600 s3 sub=b&w asw 600 I listen to 80% music and 20% movies Wondering, 1. if I should hook up my speakers to my sub? 2. what to set the crossover on the receiver to (80 for mains) for all my speakers. 3. if it is a waste to crossover at so high even if my speakers can go down to 40 or so. I think I have gotten addicted to this stuff. Thanks in advance.
