Separate PEQ for subwoofer channel

[Blaze303]

We have now separate L/R channels in PEQ which is great, but for me most of the filters are under crossover frequency. Maybe it would be possible to have separate set of filters for subwoofer? Or more than 10 PEQ filters?
Another good option would be to have expanded filter limit beyond +12db -12db, especially the low range, since we can limit max boost in REW, bot not max reduction. I could use the same filter two times to get lower value, but then comes a problem of not enough filters.

Your posting implies experience with RC and REW but I still have to ask what that sentence means. You can change the centre frequency of each PEQ filter, are you aware of that?

WiiM have already announced that they think about adding a separate EQ to the subwoofer out, but personally I don't think there's much to be gained. I prefer the flexibility of placing PEQ filters wherever I want, be it in the sub or mains band.

WiiM have also removed the option to use independent L/R room correction when the subwoofer is included in the room correction. I suppose having separate RC EQ for the subwoofer is meant to improve subwoofer integration with independent L/R RC of the main speakers.

Let's wait and see in which order these features will come (back).

I still see no real advantage in PEQ filters reserved for sub out, only.

I think they need to measure the subwoofer separately. When independent L/R RC was possible with the subwoofer my experience was that the result was too much bass due to the correlated signals in the subwoofer. You are right, no point in reserving PEQ filters, just get the level of the subwoofer to match the main speakers.

Not so much experience, just a beginner. What I mean is when I tried to set filters in 20-250hz range, REW suggests 14 filters, most of which are under 80hz. This way I run out of available filters to set for main speakers. With separate sub EQ I could set 10 for sub and 10 for L/R.

REW is an excellent tool, but that doesn't make much sense.

If I remember correctly you can limit the maximum number of filters, depending on the choice of DSP.

With separate sub EQ I could set 10 for sub and 10 for L/R.

20 PEQ filters to use over the entire frequency range would still be more useful. WiiM support sub crossover frequcies between 30 Hz and 250 Hz. In real live a single monophonic sub might be crossed anywhere between 50 an 150 Hz. Why limiting a fixed number of filters to such variable band?

Wiim stated they will expand the peq band. They also mention separate peq for sub. This is still under development so we won’t see this till next year.

I will try to find the option to limit number of filters then, thanks. 20 PEQ filters for entire range would be fine for me too, but setting separate L and R for subwoofer range is a little confusing since it is mono. Should I set them both to be the same?

Sorry, I missed the announcement. If that's the case then great, will wait for this.

Still I think that increasing the number of filters is more helpful than reserving a number of them for the sub out. Reasons given above.

Maybe if they can somewhat replicate how Dirac works which other consider the gold standard of room correction. I have no experience on Dirac because its license fee is expensive and if I did not like it I can’t get refund.

As mentioned earlier, the current room correction (RC) operates differently based on your setup:

• Without a subwoofer: RC uses independent EQ adjustments for the left and right channels.
• With a subwoofer: RC automatically switches to stereo EQ for improved stability during calibration.

Our team is actively exploring ways to enhance this process:

1. Level Matching: Matching the levels of the main speakers and subwoofer before applying independent EQ adjustments for the left and right channels.
2. Expanded Bands: Adding more EQ bands and using separate bands for the main speakers and subwoofer.

This requires extensive testing with various microphones, especially on Android devices, which takes time. We appreciate your patience as we work on these improvements, and we’re confident the updates will significantly enhance your experience. Thank you for your understanding!

Independent L/R peq rc is not included on official.

In REW what are you setting for the accuracy of the response? If you set +/-1dB you get a lot more filters than choosing 2 or 3dB

 

[harkpabst]

I don't see WiiM, being a software driven company, ever licensing 3rd party RC software. I would surely love to see them expanding their own RC software into the realm of multiple in-room measurements. But I'm willing to give them quite some time for that. The current solution is an improvement in most cases already.

Correcting from 20 to 20khz on 10 band is lacking. I think 20 band would be more beneficial.

I think 3db but I will try decreasing accuracy and limit number of filters. I have untreated room so a lot of variance in frequency response.

Correcting 20 Hz to 20 kHz isn't really a good idea with one single measurement taken in the MLP anyway.
