Probably the next version
Yeah I guess so. When would this be? Should be around now…
waiting eagerly to see if this L/R RC sounds even better… 
Updated Products Roadmap
- Thread starter WiiM Support
- Start date

L/R RC is great. Most of us do not have symmetrical rooms or the possibility to set the speakers up symmetrically in a symmetric room.
It start from amp then it follow the ultra. It will follow the rest of the line going forward.

So hear me out…
I was able to make L/R correction work even with bass management!
Your mileage may vary, but since I have an SVS SB-3000, which has 3 PEQ bands in its DSP plus room gain compensation (a fourth, LS filter with fixed options), and adjustable crossover slope, I set the room compensation in the range of 50Hz to 500Hz and ran room compensation scans over and over while tweaking the sub DSP controls (with Bypass turned on in WiiM’s Subwoofer settings so I can use the subwoofer’s low-pass filter instead of the WiiM’s fixed 24db/octave slope) until I only needed one adjustment (at 88Hz) under the crossover point (100Hz):
Then, I turned off the subwoofer entirely, adjusted the Room Correction range limiter to 130Hz-500Hz, and then ran it with Left vs Right and got these left and right adjustment curves, whereby I picked one inconsequential adjustment from each to replace:
And so I turned the Bass Management/Subwoofer back on and finalized my left vs right EQ like so and it sounds fantastic:

Thanks for sharing something interesting.
Here's the way I'm thinking of doing it now.
- Connect two subs to the WiiM line out.
- Run L/R RC with frequency range 40hz-120hz.
- Capture the results.
- Disconnect the subs from the WiiM and run a L/R RC on the main speakers. Frequency range 100~120hz-4khz.
- Capture results.
- Turn off all bands above 500hz from the main speaker PEQ and insert the sub PEQ values there instead.
- Fine tune while measuring microphones.
(I have two subs connected to the Pro line-out and main speakers to the Ultra, so I'm waiting for the Pro L/R RC to come in.)

That is a cool way to utilize multiple WiiMs! Unfortunately, I tried doing something kind of similar (used Grouping between Ultra and Mini with the Mini feeding my spectrum analyzer), and it worked great for music while…spectrum analyzing…but when I hooked my TV up to the Ultra’s ARC input, I discovered that Group playback ruined the Ultra’s ability to keep audio in sync with the video. As soon as I ungrouped the Mini from the Ultra, the sound over ARC was in perfect sync with the video, and the moment I regrouped with the Mini, the audio went way out of sync again, so Grouping makes ARC unusable.Thanks for sharing something interesting.

I don't have Ultra connected to TV, so no problem, but as you said, there is a delay when grouped.
The latency will improve to 60ms~100ms when the low latency multi-room mode that is in beta testing comes out, but as I recall the Mini is not supported...
Explain to me why this is required at all?
Cant you just do the RC with specific range (Excluding below 100Hz) and then once RC is done enable your sub-out and adjust them via their DSP?
What is Wiim radio supposed to be?

My sub is limited to 3 adjustments, and it needs one more to get it just right. Also, I am relying on the WiiM’s room correction to figure out what 4 total adjustments I have to apply to my subwoofer.

I don’t know what WiiM Radio does. I was talking about the fact that I was asking about the firmware update in general and by the time he said it was being released, I had finally received it.

Then I understand
For me it was 4 but the 4th was so minor I just ignored it, did not cause any "noticeable" issues.
Personally I ignore it if it's a -+3db or less, my bass issues are in the +23 range
Are you using your phone as a microphone?

In that case I think it would be easier for you to measure your subs using the ”House curve”-app, and adjust much faster either in Subs dsp or via Wiim.
