Questions about room compensation

[Miguelón]

Hello everybody!

I use routinely the automatic Roomfit algorithm from my WiiM Ultra to help within 30 - 300 Hz (this is the low range of my setup), but have some doubts about the adequacy of boosting some deeps.

Here are the filters:

Is the 6 - 7 dB boost above average line at 116 - 117 Hz acoustically correct?
Should I reduce to a couple dBs or even suppress it?

Are any other automatism that is introducing artifacts instead of correcting room response?

Thanks!

I would skip the boost. Usually such dips are caused by cancelation which cannot be fixed by EQ.

6dB boosts down low can make even strong amps cry.
This 4dB at 32Hz is especially painful if playback has content down there.


I would leave them alone.

Thanks, I didn’t consider that one because mainly listen to classical and jazz, but I will take it away.

What about the 4 dB one at 139 Hz between those 2 spikes?

The fact that the amp is strongly lowered at close frequencies can justify to let it as it is?

Yes. As long as the resulting filter curve stays at 0 dB or below all is fine.

Thanks, all the answers were very helpful!

I suppose the WiiM algorithm is just trying to stick as possible the FR to target curve.

It has a Non-Boost mode, which I didn’t activate. I will run the calibration again with this option, to see if it refuse to go over the baseline.

Yep, it was the Non Boost option, I feel like an idiot.

But at least I learned something about the positive gain boosts… thanks again.
