The AVAA traps. 1-2db improvements? I don't get it.

It's +\-2db from the target curve down to 20hz.
Lost interest in what? I could improve the step response a little more. I'm thinking about getting another stereo amp and time aligning the JBL woofer with the horn compression driver to make the speakers fully active. It's not a high priority but if the right stereo amp comes along, I might do it.Now that you're done, have you lost interest yet?
Have you purchased Mitch's book on DSP and Acourate yet? It's available on Amazon Kindle. It's $10 and well worth it. He goes into a lot of room acoustics science and connects it up with Acourate in a detailed and logical way. It's very helpful. The only problem with it is that all of the examples are from his fully active DIY horn speakers. It's sort of depressing looking at how well his speakers perform.Oh, you're not done. Nevermind...
Oh, what is it called? Inquiring minds want to know.Have you purchased Mitch's book on DSP and Acourate yet?
It's very much geared to Acourate users. So you'll prolly want to skip over some parts.Oh, what is it called? Inquiring minds want to know.

I'll take a look at the book.
I have AcourateDRC, not Acourate. It doesn't have all the complexities exposed for fiddling, and is dedicated to creating IIR and FIR filters for the miniDSP OpenDRC exclusively.
IIR - biquad filters - do the work on the lower end, and the FIR does the higher frequencies and minimum phase corrections.
Basically, create a target, take a single measurement of both/left/right, pick among two more/less aggressive settings, decide how many of the available IIR filters to use, and press Ok.
From the miniDSP, download the filter and continue.
FIR L/R filter at top, the combination of IIR filters L/R below, sum those together to pretend you can see the final curve, phase adjustment not displayed.

Is setting the range of the graph's y axis to 160 dB, and measuring response at only one position in the modal region with 1/12 octave smoothing covered in the book?
Modal region measurements should be unsmoothed and EQ'ed as such, and checked at multiple listening positions.
