I use 25-500hz and 25-3000hz depending on the source and volume.
I wrote about the PEQ setup here, but right now I have 2 subs connected to the Amp Ultra sub out.

So far so good, unlike correcting full range (all the way to 20KHz), my soundstage remains both wide and deep, with layering, even with correction to 1800Hz. Going to 20KHz was completely wrecking the soundstage. Not so with this cutoff.

In the end I decided I wanted better control over my crossover timings while remaining able to apply DIRAC to my entire chain. I ordered a second miniDSP Flex, this one with RCA outputs and no DIRAC, and I connected it via Toslink to the second output of my main miniDSP Flex with DIRAC Live license (digital in/outputs model), and then used this wonderful guide for utilizing REW to time align all five elements of my system:

After that, I set up all my crossovers (70Hz for the PC-2000 Pro to the 3000 Micros, and 155Hz for the 3000 Micros to the LS50 Metas), and then applied DIRAC Live (applied from 14-3000Hz). Here are the sweep results (the left and right sweeps are more important to focus on for full spectrum; the combined sweep really only matters maybe from 300Hz and down):
By inserting the second miniDSP, I improved the integration of the large sub, as it has the ability to control timing delays down to the hundredth of a millisecond. Additionally, it has much better slope control for the crossovers. I also was able to reduce clutter since it replaced a DSPeaker Anti-Mode that I was using for room correcting the PC-2000 Pro and also an SMSL SU-1 DAC that I was using for the 3000 Micros, I placed it directly next to the original miniDSP and bought a small media rack to place above them together. I have the WiiM Ultra now locked into, “bit-perfect mode,” by locking volume at 100%, turning off all EQ/RC/Bass Management features, and use the primary miniDSP as digital preamp. Please excuse the Bezalel phone charger; it is blocking the IR port of the second miniDSP so its volume doesn’t change when I adjust the main miniDSP.

I was able to get an impressive upgrade in imaging by rotating the 3000 Micros 90° so they fire perpendicular to the axis of the LS50 Metas, and then raising them and placing them directly behind the LS50 Metas so that they are actually coaxial to them to the main listening position (really getting as close as I can to simulating a, “poor man’s Blade Meta”). I also moved the PC-2000 Pro between the speakers so help shift the sub-bass bloom to a position closer to the center of the system. This all necessitated moving the speakers slightly farther forward and outward. Everything was then re-time-aligned in REW (applied to the stacked miniDSPs) before recalibrating DIRAC Live. The sound has reached its peak, just unbelievable realism.

Finally decided to get some proper stands for the 3000 Micros.
I also ended up deciding to get less aggressive with my crossover points, so I lowered the crossover between the LS50 Metas and the 3000 Micros to 135Hz and the crossover between the 3000 Micros and the PC-2000 Pro to 50Hz. I also plugged the port on the PC-2000 Pro and set it to sealed mode. I’m getting extension down to 13Hz before it starts rolling off!

Here are the left, right, and combined sweeps when I apply DIRAC Live from 13Hz-13KHz (profile 4 on my miniDSP):
And here are the final left, right, and combined sweeps when only correcting from 13Hz-300Hz (profile 2, my preferred listening configuration; I also have a profile correcting 13Hz-800Hz and one correcting 13Hz-1800Hz):
I find the overall sound more natural and I like the slightly heavier mid/vocal-focused voicing with correction only 13-300Hz.
