Sorry for the delay, I had trouble with my internet connection in the past few days

Well I'm not saying the wood paneling is necessarily what causes the dip, but sharp nulls are resonant absorbers generally, or cancellation due to phase mismatch in two sources playing the same signal. The dip you had at 56 Hz is relatively wide, so it's hard to see if it's indeed a dip/null, or if instead you have a peak at 45 Hz and one or two others at 70-80 Hz. Peaks at 45 Hz are extremely common in most rooms and correspond to a room mode for a linear dimension of roughly 12 ft. So you may have better luck trying to level those peaks down to the 55 Hz level than boosting 55 Hz to the level of peaks on either sides... If those are peaks of course, which I'm not sure by the way
But after we find final position can we treat medium to minor dips with the mini?
I'd say there's no harm in trying! But, if the attempt does not work well, better delete the useless filters; they will pump acoustical energy into the dip for nothing and can impact the other filters.
Let's use what I did last night as a teaching moment. I took three graphs. Pre dsp raw, post dsp&pre audyssey, and then post dsp&audyssey. I tried to present Audyssey with less work. I did get a better looking graph but perhaps it's not good as the REW thread regulars have left my post untouched with zero comments. I don't know, I'm just trying to learn ya know
Well I think you're certainly doing well -- that third graph is pretty nice overall. Minor peaks and valleys but roughly flat to... OMG
By the way, I was advised to run Audyssey first and tweak its results with EQing afterwards. In any way, if you want to try a non-flat EQ, you *have* to apply boosts post-Audyssey since Audyssey will always try to EQ flat. But it's certainly hard to argue about your results.
Also keep in mind that if you did a full 8-position Audissey MultEQ XT32, it tries to optimize bass across all 8 positions. We seldom have the time and willpower to take REW measurements across 8 listening positions and average those. So while you may want to optimize flatness for a single listening position, keep in mind that Audyssey's results are better than it seems at first sight because of the multi-position optimization.
You might also want to sit back and enjoy your work now for a bit before spending a few more hours on EQing. With that FR, your setup should sound really awesome
