I know there's been alot of discussion on subwoofer setup and calibration lately, but I have a couple of questions I'm a little confused on. I'm currently running a Paradigm PW-2200 sub (yes, I know I need to upgrade to an SVS...I will as soon as humanly possible!!) I recently moved into a new house and I had the sub calibrated quite well in my other house. The new house, however, isn't being as cooperative. Anyway, in Ed's excellent explanation of sub calibration, there's one point I'm confused on (and have always been confused on). What do I set the crossover on the back of the sub to? Ed says "crossover switch to off." I'm not sure I can do this, other than turning the crossover as high as it can go. Is this correct? And if so, why wouldn't you set the crossover to the same level that the receiver's crossover is set to? One last question...the phase control. I've never really understood the best way to set the phase control. Anybody got any suggestions?
