Re: Crossovers..

Its not generally a good idea to have a crossover point higher than 80Hz because the sub will usually be localized and can become "boomy" for lack of a better word.
No matter where you put a crossover the information as Willis stated will be sent to the main channels if set below 120Hz (as long as your mains can handle it)

Home theater:
Onkyo 805, Yamaha YDP2006EQ, Samson Servo 600 amp
3 EV Sentry 500 monitors across the front, 4 Mission 762i's Surrounds, SVS PB13U sub, Panasonic BDT220, Harmony 1100, Nintendo WiiU
Panasonic PT-AE8000 on a 120" 2,35:1 fixed screen

Living room system:
Sherwood/Newcastle R972, Mission 765's, SVS SBS02's, A/D/S MS3u sub, Yamaha YDG2030EQ
Yamaha KX-393 Tape deck, CDC 805 CD changer, Panasonic BD60, Sony turntable PS-T20
Panasonic TC-P50ST60, HD-PVR & WDTV Live, Harmony 900

On the psw110, use the LFE connection. It's yellow on those subs. This will bypass the internal XO. No guessing. How did you end up with one of the subs at 0,and one at 180? Just wondering if you measured them in room etc.

Ok. Not sure what vintage you have. The other way I've seen is to use the red, right channel input and turn the knob the the LFE setting.

Re: Crossovers..

the phase is 0 on one and 160 on the other. I am pretty sure the polk forums told me to put them opposite of each other or they would cancel each other out? were they right?

its the phase button not the Xo.

Sorry, missed this one. That's a good starting point, but every room/equipment/placement/crossover point etc is different. Do you have an SPL meter? Put it in the LP, Run the test tone, and switch the polarities (both to 0, one to 180, then both 180 and reverse 0/180. 160 for yours?). When you see the most output, that's where you should set them. That should give you the most even tight bass. Cheap dirty method could be spl meter app for phone. Tone generator apps are useful too.
