Quick rundown...
Outlaw 990
Dual SVS 20-39 PCi subs hooked to a Behringer DEQ2496.

Issue: Currently I have the unbalanced outs going to each channel on the DEQ2496 and then the DEQ2496 going to the subs. Same config I had with my B&K Ref 31.

I've had to calibrate the 990 to -14dB on the Subwoofer to even get it within 5dB of the rest of the speakers - i.e. my speakers are all calibrated to 75dB and the sub to about 82.

The subs level (volume) knob is set to about 3 out of 10 on both subs.

Why is the sub level so high? It doesn't seem like there is any way to even get the subs at 75dB like the rest of the speakers.

The DEQ2496 is showing about 20Hz - 120Hz at measurable levels to the sub so it's not like I'm getting a full range signal that's skewing the results. I can't turn the subs down much lower because they're at 3 already.

I tried putting an XLR "Y" cable in but that made my sub level at the -14dB calibration to be at 92dB instead of the 82 of the unbalanced inputs.

There is an EQ gain on the DEQ2496 - should I drop that 10dB? Would that degrade the signal more somehow? Is there anything I'm missing here that I should be doing?
