Well, after playing around with REW for a few weeks...I finally got a hold of BFD.
I took a measurement of the SUB only...then of the SUB using the EQ filters suggested by REW...then of the EQed SUB w/ RIGHT MAIN.
This is what I got.
Sub Only:
Sub EQed using 2 filters suggested by REW:
with Mains:
I thought I was doing ok...but then the measurement with mains kinda thru me...the plot beyond 155ish HZ looks messed up?
I tried adjusting sub phase and speaker distance and that is the best I could get.
Thoughts? I am still not entirely sure about the accuracy of my measurement...I have a hard time getting the same result twice...
