Setting up LOWPASS and CROSSOVER for my system

[CrazyEightyNine]

I read all about setting up lowpass and crossover but I guess I'm just not getting it. Any help?

My Equipment:

Yamaha 7.2 Receiver RX-V863 (bi-amped for my 2 fronts)

Klipsch RB-61 (fronts), RC-52 (center), RS-42 (rears), RW-10d (sub)

-For the sub I can set the LOWPASS from 40hz - 120z (by 5s) or "off"
SPECS: Freq. Response 28-120Hz +/-3dB and 260 watts continuous RMS wattage

-For the receiver I can set the CROSSOVER to (40, 60, 80, 90, 100, 110, 120,160, or 200hz)
SPECS: RMS Output Power (20Hz - 20kHz) 105W x 7

-For the Speakers
FRONTS: Freq. Response 43Hz-23kHz +/-3dB (100W RMS)

CENTER: Freq. Response 67Hz-23kHz +/-3dB (125W RMS)

REARS: Freq. Response 52Hz-23kHz +/-3dB (75W RMS)




*NOTE the sub cable uses a Y-adapter before it goes into the 2 RCA jacks on the sub

*ALSO I don't really understand "PHASE" on my sub but at the moment its at 0 degrees and my subwoofer is in the front left of my system. Is that correct?
