HK630 with M60s at 80, VP100 and QS8s at 100, sub crossover is bypassed. I still have a nagging feeling that the system sounds the tiniest bit better when all the crossovers are set to the same frequency (I have tried both 80 and 100) but I can't even describe the difference or even have confidence that one is better for sure.

I am kinda thinking of setting everything to 100 again, just to mess you up
