Share your RoomFit curve

[KolegaPaweł]

Hi, if this post is stupid, then I'm sorry. But I don't know how good RoomFit curve should look like I tried to compare mine to others but it is hard to find many examples. So my idea is to open a thread where everybody can share theirs curve screen shot so others can comment on it.

I have triangle shaped room at the attic. Should I work on it or is it good enough right know based on this curve?

RoomFit does not deliver acceptable results in my setup. Applying the resulting EQ corrections everything sounds hollow and anaemic. Useless for me.

Having said that, the same applies to Lyngdorf‘s RoomPerfect. And that was in two different houses! Always the same bad result.

I really don‘t understand the hype. Both models will eliminate standing waves in the bass region but so thy do to the rest of the sound. A few manual minor tweaks using the graphic equalizer on the AmpUltra did a MUCH better job.

They don't do anything to the rest of the sound unless you choose a frequency range that extends to higher frequencies. Of course the overall sound balance will be different after the bass humps have been removed. You should try the RoomFit "Evaluate" function to see how your adjustments affect the frequency response, but only after the fixed version of the WiiM Home app is released since they managed to break that function with the last release.

Yeah, I might try again later. But really, I don‘t feel that I need it. Thanks anyway.

The ‚bass hump‘ detected by RoomFit led to a correction of -12db at 60Hz!!!!
BS, I say. Manually taking it down by -3db solved my bass problem.

Mine also has a big correction around 60Hz. At the moment I am using flat target but individual channel which boosts the bass a bit. I also have the B&K target saved depending on how I feel on the day

Welcome Pawel!
Doesn‘t look bad to me! Difficult to tell, not knowing your setup and speakers etc.
At the end of the day, your ear tells you if it’s good or not…

I also decrese the level of bass correction, but not so much!
In my case, the place where the correction happens is perfectly correct.
It is also a personal preference and maybe also a bit of habit - the ear get accustomed to that… I (also) like it a tad bass heavy…

Unfortunately, the curve showing the RoomFit result doesn't say much and is not easy to compare between systems.

RoomFit settings like e.g. target curve, lower and upper frequency limit can be totally different. Different microphones will lead to very different absolute results. Pretty much all smartphone mics show this disgusting hump around 8 kHz, while measuring microphones with calibration files do not. The dynamic range shown on the RoomFit results screen is not always the same, making visual comparisons difficult.

There might still be some value in comparing the results, but it's probably more limited than you think.

Just got my new Apollon Purifi 9040 DM amp today and set it up with the Ultra.

This is a different beast than the AmpUltra all together! It became very apparent playing around with the EQ settings. I can now completely omit the reduction at 60Hz; I can even level it up and have considerably more and tighter bass.

So appropiate EQ settings are obviously a matter of amp capabilities.

Now I‘ve got a new problem. The additional bass described above leads to a resonance of my metal low board which houses not only the hifi but also my land line phone in its loading tray. This is switched off and only occasionally turned on to load the phone.. The display of the phone is set to be off when not loading or in use.
Now it frequently comes alive from the resonance thinking it‘s been picked up .

Really surprising ...

This sounds a bit sarcastic. And I suppose, that‘s how it was meant. No problem, because you probably do know more than I do.
I would indeed have thought that the AmpUltra with its 200w into 4ohms would be capable enough. Leaving aside any other factors one amp might do better than another.
But I guess I was wrong. One cannot seem to have enough power for bass control.

You're quite right regarding the sense of irony .. I wouldn't say it's sarcasm.

Technically, power and bass control are still not related. Make sure you enjoy your new amp to the fullest (and I have no doubt it's absolutely amongst the best money can by, no irony here). But also make sure to not be taken away by initial exuberance and enthusiasm. There's simply now way that an audible peak caused by lack of bass control would no longer need correction with the new more powerful amp.

Remember you can use the WiiM Home App and RoomFit evaluation to objectively evaluate the bass response, at least with most smartphones. And this is close to how this thread started.

Point taken. My initial bass correction was indeed based on the RoomFit analysis done by the Amp Ultra.
But that only assisted me in locating the critical frequency spot. The extent of the correction was then dictated by me.

I’ll run another RoomFit analysis with the new setup tomorrow. My guess is that the result WILL be different. We‘ll see.

Did you set any crossover or speakers play full range? I think you could lower your sub volume to naturally match yellow line. What mic did you use?

 

[Jimmy]

你設定過分頻器嗎？音箱是全頻播放的嗎？我覺得你可以把重低音的音量調低一些，讓它和黃線的音量自然匹配。你用的是什麼麥克風？

I'm using the microphone on my iPhone 12 Pro Max, with the frequency breakpoint set to 80Hz.

I'm using the microphone on my iPhone 12 Pro Max, with the frequency breakpoint set to 80Hz.

When using the iPhone's built-in microphone, it may not be picking up sounds below 47Hz. (Despite having a subwoofer, you can see it rolls off below 47Hz.)

How does the sound after RoomFit? Can you hear the bass below 47Hz clearly?

Your response after correction looks pretty good (most importantly there's no nulls - good work with placement!) so IMHO nothing needs to be improved; however if you'd like to play with it more I'd suggest the following modifications:
1) Reduce subwoofer level by about -5dB
2) Enable the RoomFit "No-Boost Mode"
3) Use the "Individual Channel RoomFit" option

Here's an example of just a few threads where we guided other members through placement and RoomFit optimizations, with lots of examples:

• Wiim Amp with Polk XT15 & Polk PSW10
• RoomFit Help Guide
• How to think about room correction settings like frequency range and gain?
• Wiim Amp Ultra - Polk Audio XT20 & SVS SB 1000 Pro - Configuration

Lastly, as I wrote before:

• Speaker/sub placement is really critical, and needs to be optimized first for RoomFit to work well! This IMHO cannot be overstated. I provided some placement advice and explanations previously in this post.

This post may also be useful (note that since the time of that post RoomFit algorithm was updated and I'd now recommend to limit the upper correction range to about 200 or 300Hz, depending on the specific situation).

EDIT: In case you find it useful, here's my recent RoomFit result from a system based on Revel M16 + SVS SB-1000 Classic:

The sound below 47Hz is there, but it's a bit muffled. Should I add an external microphone to correct it?
