Hello.My 7.1.2 system consists of: Jamo C809 fronts(30-24000 Hz),Jamo C80 center( 70-24000Hz),Jamo C80 surrounds(65-24000Hz) and Jamo C93 for surround back(45 Hz-24Khz).I set the crossover in the Receiver(Pioneer sc-lx88) at 80Hz and set all speakers to SMALL.Set the crossover in the Subwoofer at 150 Hz(Klipsch R 115SW).Should I raise the crossover point above 80Hz in the receiver? I'm thinking that the pair of surrounds and center speaker that won't go below 65-70Hz are the weakest from all of them(in that matter) and probably the cuoff frequency should be around 100 Hz.Thanks
