I asked about a crossover here before and I was wondering. If I set my FRONT=LARGE and SUB=NO and ran my speaker wire through a high-level crossover, and then sent that to my subwoofer, would that work ok? I know its not ideal, but didn't subwoofers used to do that anyways? My receiver has a 100 hz crossover and I'd like to try 60 to 80 hz instead. I might even even run the low pass from the crossover into a BFD DSP1100P model or the DSP1124P before going into my Mirage BPS-400. So I know a line-level crossover is best, but could I even make a high level crossover like I'm talking about? say with a selectable or variable crossover for high and low pass of say 60 to 90 hz? I would put the crossover right behind the receiver, as close to the receiver speaker connections as possible, because from there, I would still hope to connect to my speakers bi-wired. So where can I find a selectable high-level crossover? Or would I have to make it myself like people mentioned earlier?
