Unfortunately with rythmik you'll have to use LINE IN instead of LFE to use phase control. I recommend keep PEQ switched off, use mid damping 20hz rumble off if you plan to use audyssey/room correction and make sure the crossover is set to AVR and max.
It's super easy to do with REW since it has a built in spl meter that will work with the built in mic on your computer(uncalibrated) or if you have the UMIK-1, just plug and point it towards the ceiling at the main listening position. Once you plug it into your computer, REW will detect it automatically, select the 90 degree narrow band calibration file if you have one from CSL. Click the SPL meter icon for SPL, Press Z if you have a calibration file C if you dont, press S for slow, HP for high pass, press the red icon to record level from the mic, then play the test tone from your receiver/processor with the subs speaker level at 0 and adjust the gain on the actually sub each one at a time by powering each sub on/off manually if necessary to attain 75db from each one, then and adjust the phase on one of them with both subs powered on slowly until you get the highest spl, should be around 80-81 with both ouputting. if you have an HDMI output on your computer you can cable you can use that as an input with the built in signal generator(for test tones instead of your processor - results would be the same), select pink noise and sub cal, LFE would be the ouput channel. Same process for windows/mac. I think REW is very user friendly. That will give you a good baseline to start audyssey. If you have the HDMI output, you can then do measurement sweeps to compare different sub settings, positions, before/after etc..
