Before you read this...I take it all back. I made a mistake and was measuring where I thought it was ok...but it wasn't. Skip this post....but read further on in this thread...then...come back and look at these measurements.
Lesson #1....measure exactly where you sit. It's not "close enough".

Hi everyone...sorry it took me so long for another pass (I'm sure y'all were on the edge of your seats...kidding).
I started over and got down to 6 filters and came up with this.

I can live with this. Might tweak a little more.
Unfortunately, this created a sound that was quite annoying. Bad enough that I turned down my sub and I actually felt a little relief when I bypassed the BFD.
So...my wife is out of town tonight, so I was able to do some longer term playing.
I went ahead and ran a full range scan in the lower range and got this (this is BFD w/ 6 filters and all speakers on).

No wonder it sounds funky. I probably wasn't bothered by it too much cause my x-over was at 60 pre BFD. Right now I'm at 80.
So...guessing that it was a phase problem, I inverted it and came up with this (again...BFD on with all speakers, x-over at 80).

I still have that mid 50s problem (even on my sub alone)...I guess that's a room problem. In my filters...I have 50+3(51.95) +15db, 7.3hz wide. I guess I can try to put one just to the right of that (right at 55) and try to work some more on that dip.
Thoughts?
