Hi all - just got finished using REW w/ BFD to eq my sub with my new Yamaha RX-V1800 receiver. Overall I feel the calibration went excellent. However I have one nagging issue I can't tame that I'd like your feedback on please...

I use a house curve of 20 8.0, 80 0.0 and obtained a nice smooth response along the curve. The challenge is that I have some peaks in the 75-95hz range THAT ARE COMING FROM THE FRONT SPEAKERS, not my sub.

I tried making various changes with filters to address it, but these filters do not help (not surprisingly because the issue is with the mains).

Take a look at the attached graphs to see the peak. The first screen shot is with the mains + sub, the second is just the front. Both have 1/3 octave smoothing applied.

My main challenge is that I have no way to equalize the mains. The Yamaha uses YPAO to balance things out which I like to use. However with this engaged I cannot also then use its manual EQ function to remove these peaks in the 80hz area.

The main thing I am wondering is how important it is to remove this peak. It seems to be about 6db or so, which seems significant but not necessarily horrendous. So I'm thinking that perhaps its not going to make a big difference to remove it and therefore just not worry about it. Or is this worth focusing on?

The other thing I'm wondering about is how I can even go about addressing this. I don't want to lose the YPAO functionality because it adds benefits outside of the sub range. And with it I then have no manual eq option for the mains.

Any advice greatly appreciated!
