I finally got REW set-up on a laptop, using a Behringer ECM8000 (didn't use Sonnie's calibration file) with a Behringer Xenyx 802. On the Xenyx, I set EQ for high, mid, and low to be zero (at the 12 o'clock position), the FX to negative infinity, and level at zero. Is this correct?
I used the RCA outs, connected to the SB Live External box (line inputs), with the outputs going to my Pioneer receiver (with MCACC turned on). I've attached both the 20-263 plot, and the all freq. Any comments? Also, any suggestions on the huge dip at around 106 Hz? The crossover is set to 80 Hz in the receiver. My speakers at Axiom M80Ti and the sub is an HSU VTF-2 set to max extension. NOTE, I did run the measurements with the output of the SB directly to my external amp (thus bypassing my AV receiver) and I see this 106 Hz vacuum as well in both L and R speaker.
Any help would be greatly appreciated!
