Here’s the combined sweep:

Just got the Luxsin X9 in and set it up. Didn’t even put my Anti-Mode X2D in the chain (yet), simply worked with the 3 PEQs in each sub’s DSP, set crossover (used 30dB/Octave slope) in the X9, checked phase settings in the subs, ran a WiiM RC calibration, and already witnessing divine sound. Bass should clean up even more once I get time to set up the X2D, but I might not even bother!

Dare to elaborate?
Hi!
Yes, of course. It just didn't send, it turns out.
This is the result I achieved. Don't pay attention to the HF drop, the sweep tone was cut off there. For some reason, it always drops off in the upper range when connected via USB.
I used to always do Harman. This time I decided to go for a flat response. And it's awesome. Now switching to Harman doesn't sound comfortable.
I achieved this result after adding more foam to the roof and finding the perfect blend with the subwoofer.

Did you consider B&K? It’s more mild than the Harman curve. I have found that there are sounds which are completely missing from normal listening unless at least B&K if not Harman curves are used. For example, on Dizzy on the French Riviera, No More Blues, there’s a deep sound of the waves crashing onto the beach and it needs a tilt or boost on sub bass to play. On the live concert recording of Eric Clapton playing Layla, without the bass boost, you can’t feel his foot stomping to the beat.
I ended up trying out DIRAC on my laptop and the result simply sounds another level improved over any previous room correction I’ve tried. No comparison. I’m still trying to figure out the best way to get a sweep out of the system with DIRAC active to show the results, but in the meantime my ears have never heard better from this system. As I must use the laptop for streaming to take advantage of DIRAC, I’ve since removed the WiiM entirely from my system, with hope (but no realistic expectations) that maybe in the future, WiiM will add the ability to buy a DIRAC license and apply it to the WiiM because RoomFit doesn’t come close. Having done that, my system is significantly less cluttered as well:

I have just the opposite example. After switching to flat, I heard things I had never heard before in tracks I know. For example, in one track, I can hear the guitarist tapping his hand on the guitar body. When I switch to Harman, this sound is not audible due to the excess bass.
However, for tactile sensations, I boosted the equalizer to the maximum at 30 Hz.

For some reason, it seems to me that you have a phase problem. That's why Dirac gives better results — it also aligns them. But Wiim doesn't.
Although you have KEF speakers, and they should have linear phase response.

The phase issue I had previously was due to the inconsistent sync timing when grouping two WiiMs (one for speakers, one for stereo subs); this was obvious because whenever multiple sweeps are run consecutively with UMIK-1 you see the frequency response at and around the crossover frequency would change with each sweep despite no change to any phase or delay parameters. Once I switched to the Luxsin X9 for bass management (it has a stereo subwoofer output), the phase issues were gone as the response was consistent--it certainly helps that the X9 has adjustable slope, unlike WiiM, as well as adjustable delay (with the latest beta firmware). DIRAC was then applied after the subs were correctly synced to the speakers using the X9.

Then everything is clear! The problem is indeed in the phases.
I have the Ultra, and it has a subwoofer output. The first thing I do is run the delay setup between the sub and the speakers. Only then do I proceed with the correction.

I run stereo subwoofers. WiiM only has mono sub output
My crossover is 150Hz; this eliminates the vast majority of distortion from LS50 Meta, which is primarily under 200Hz and dramatically increases at 160Hz and down, especially when played loudly.

Finally figured out that I can use AirPlay from my phone to my laptop to perform HouseCurve sweeps. Here’s what it looks like now with DIRAC Live correcting my blended 2.2 setup:

I always enjoy reading your thread
DIRAC appears to be increasing the volume of the Sub, is this due to DIRAC? (Does DIRAC season the tone with its own target curve?)
Comparing only the response, it seems that #32 was also superior. Also, the high frequency curve is very different in every measurement, which frequency range is being corrected?

If I am not mistaken, the target curve I chose was Harman, which is steeper than my previous method (simply set sub volume a bit higher), but it sounds amazing—there is so much slam now with things like kick drums due to the combination of the steeper curve plus the impulse correction of the DIRAC Live correction. I find the high frequency portion curious as well. This was measured with UMIK-1 pointed up, using 90-degree calibration file. Just minutes prior to this sweep, I had run a sweep using the iPhone mic and it actually showed elevated response in the high frequencies. Of course I am inclined to believe that the iPhone mic is less accurate. What may be happening is that the iPhone mic compensation was still active as I plugged the UMIK-1 in mid-session. I shall take another sweep later when I get home, and make sure to use a fresh app session.I always enjoy reading your thread

Here are the left, right, and combined sweeps:
The dip at the high end appears to be interference/cancellation between left and right channels as it only occurs in the combined sweep.

DIRAC is stunning; the only real card left in Bluesound’s deck—otherwise WiiM has truly stomped them all around.Excellent result
-Ed
Are you currently using Bluesound?
If you added WiiM to your current system and layered manual PEQ, would you be able to flatten the Sub's response further?

No, I actually am in my 2-week trial period for DIRAC Live on my Apple MacBook. I am currently trying to decide if I should buy DIRAC license for the Mac when the trial ends and continue using my MacBook as my streamer, or if I should get a miniDSP Flex with DIRAC instead (then I can put the miniDSP between WiiM Ultra and Luxsin X9).Are you currently using Bluesound?

The dip in my bass is primarily due to SBIR cancellation at my main listening position combined with some interaction between the two subs as it doesn’t show up much in the individual left/right sweeps. I think I need to change my listening position to really fix that dip.
