I agree totally. I've rerun RC many times since and also added a sub to my setup which has certainly helped the bottom couple of octaves. I've also limited the max gain to 6dB. This is what my PEQ looks like now.
How to use Room Correction?

It certainly will not sound bass heavier per se!
In my room it happens something similar. I have modes at around 50Hz. RC is decreasing there massively, but increasing again at 38 and even at 25Hz. (Sub goes down that deep).
Modes are almost gone. Less bass, but more refined. A massive improvement!
Actually the Mic is on the Bottom Frame on bot sides of the USB-C / Lightning Port. So, Not Front...
Just read!
My words. At bottom, moved towards the front of the loudspeakers… Sorry English is not my first language.

One picture is worth more than a thousand words.
I am confused, do I have to point it towards the corner?
Ps: I removed the handy cover for the measurements…

I use a Mini in my screened porch system. I'm not sure room correction would help in such an open area. Any thoughts?
I don’t think so. Rc works in closed space.
RC works "best" in a closed space, but one could still anticipate "improvements" after running RC for this "screened porch" usage.
The RC Measurements would still highlight the Divergences from the Test Tones, and would provide suggested PEQ to counteract such.
The challenges would be significant - background noise would be hard to control. Running RC at 3AM to avoid Traffic and Wind would likely PO the neighbors - especially the repeated runs to average out results.
Alright, it‘s here L/R RC and Smoothing filters…
Conclusions:
1) works reliable and replicateble. Except for me above 8k, the iphone measures steadily increasing level up to +12db at 16k… -for me it works fine upto 4k!
2) In my Room LR correction is not needed (I have an even room, there is one wall at the right side around 1m from the loudspeaker that is missing on the left side. Apparently the impact on sound is notthat big… ~1-2dB > not worth correcting)
3) Smoothing makes sense, however I do not need it, as I did it intuitively already before by slighly adapting gain and Q values in the RC curve. 1/12 is much to sharp, 1/3 slighly to smooth (but still ok), 1/6 is indeed a good compromise to start with.
4) I continue to use happily the stereo mode…
Nevertheless, great effort WiiM-Team!

@WiiM TeamUpdate on L/R RC!
The best sounding option now is indeed L/R RC! It sounds slighly more spacious and instrument seperation is more pronounced. (I only correct between 20Hz and 500Hz - maybe I expand that in the future further above, with a better microphone than iphone 12, but for now it‘s ok)
However, I am not only listening at one position in the room (large loft like room).
For other positions the stereo settings for bass were better - so I combined the two…
I used the L/R settings and replaced the settings below 100Hz with the stereo settings! Happy!

Still waiting for them get L/R RC working with a sub. I intend to try it with REW with a modified target curve to cancel out the bass boost caused by the correlated left and right signals to the sub. Presumably this is the reason for the absence of L/R with sub but if it is why don't they say so instead of the vague and woolly "It doesn't sound good"Update on L/R RC!

I use WiiM P+ wired to my Amp with 2 subs… works perfectly.Still waiting for them get L/R RC working with a sub.

Well I've run RC again. Similar results. It sounds....ok, quite neutral. Takes the edge of some vocals (probably a good thing, I listen to a lot of metal). Can't make my mind up if I prefer it Vs plain old EQ. Been tinkering with a custom one - see below, am 80% happy with it. It brings out some ridiculous detail sometimes - Drop Dead Legs by Van Halen, I could hear the ride cymbal massively prominent, never heard like that before!)

Your Graphic EQ will turn off the Room Correction EQ completely. Shame you can't use both really.

Yeah I know, I do slightly prefer it

When I was using an external mic that rolled off viciously at the low end I convinced myself the room correction results were OK even though it was boosting the low frequencies when it shouldn't have been
. I was probably closer to a Harman curve than my chosen Flat target. Since using a flatter mic I've changed to B&K

I've found using the B&K curve with L/R correction has made my ears the most happy, especially using an external mic(iMM-6C in my case). Soundstage is wider, more detail, just plain better overall.
Indeed, I tried all 3 but but bk sounds the best. I thought flat would give the best because every measurements and reviewers aim for that response. It lack the depth and soundstage.
