Please note it is usually better to have independent delay control for each subwoofer. Speaker Level Using an SPL meter set to c-weighted slow response, place the unit point up at the ceiling at the appropriate ear height and location for the main listening seat. Using the main front speakers as your reference channels, adjust the master volume until the SPL meter reads 75dB when the left front speaker is playing the test tone.

Next calibrate each speaker to that 75dB reference. If your processor has independent multiple subwoofer outputs and trim controls, set the sub level to within a few dB of the other channels. Next reconnect the sub and disconnect the calibrated sub and repeat this process. Once you have completed the level matching, connect up both subwoofers and lower the sub level control on the processor if the level has jumped up when both subwoofers are playing the test tone.

I currently have them setup like in figure 1 with both in the front location.

I'm going to try the midpoint location on the front and back wall since you indicate that is the best location. My question is should I first do the subwoofer crawl with the one sub at the front of the room, plug in the rear wall sub, run Audyssey MultiEQ, readjust levels with a SPL meter to ensure each is at 75db? Just want to get the steps down so I'm not doing numerous times to get this right Thanks for any help you can provide. Are you planning to review the powered Triton speakers?
