SVS 20-39PC+ , RF-3s and Outlaw crossover setting

[Gametester]

Well I've had the SVS 20-39PC+ up and running for 2 days now and WOW (a co-worker commented on how you could wear it as a barrel

I'm having some calibration issues though.

I'm running Klipsch RF-3s, RS-3s, RC-3II with an Outlaw 1050. I've set all speakers to small, LFE 'on', -15db sub trim on the Outlaw, Outlaw crossover set to 60Mhz, SVS 20-39PC+ corner loaded, SVS crossover disabled (set at 120Mhz), SVS phase at 180 (though I did not hear much of a difference with any setting), Gain is a tad more than half, calibrated via VE/Avia (back and forth) and a RatShack SPL. There is still BIG bass to be had, I'm just not finding the happy 'blend'.

Would setting the outlaw crossover to 80 yield much difference? (I'm not sure that my RF-3s would be better off passing that off to the SVS or not).

It feels like I have the Outlaw Sub trim really low, the lowest it can go, this a good thing or a bad thing? Better to have the Sub do it all or turn the sub down and boost the Amp feed a bit?

I also noted a good amount of grounding hum (maybe?) with the SVS crossover disabled (goes away when set to enabled). Not hum from across the room, just when it's quiet, you can hear it when you are a few feet from it.
