Hello Jcambron,
I, also, have two Rel Strata IIIs, and I have them set up on opposite corners behind my front speakers. I followed the instructions, as per the manual, to set up the first one. I measured the exact distance from the back and sidewalls and put the second sub in the other corner the same distances from said walls. The effect is amazing. With one sub set up I had many dips and peaks throughout the room/apartment, and I never really felt the bass was right. Once I got the other one home and dialed it in, all the dips and peaks were gone and what remained was bliss. others may have different solutions to your situation; I'm just giving you what worked for me, YMMV. Good luck, once you get it right, I think you're really going to enjoy the sound.......John
