I think I got it right, but I thought I should ask. I just got a 525 in a week ago. Running paradigm studio 60's, CC, Atlantic Tech 374 rears, and a PW-2200. I've played around with the crossover settings in the HK, and I think I've settled on these settings. 60 cycles for the mains and 80 for the center and surrounds. Right now I have the sub crossed at 60. My questions is, do I set the sub crossover for 60 or 80? I've set the sub's own crossover to it's highest point (150 Hz I think), since the HK should handle it's crossover point. Is that correct? Thanks for the help.
