Excellent Web-Based Parametric EQ Tool for WiiM Ultra

In your latest measurement there is still quite a big spike at 8k that I would try to tame. Next step would be to establish what is causing all that energy >3K. If it’s how the the speakers are designed, I would personally be looking to replace them but it could be their positions, room reflections or other factors.

Tommy Emmanuel's tone sounds perfect, but when I switch to rock or metal, something's missing, that full bodied, heavy riff sound you want from metal. Jaco Pastorius sounds good though.

You have a few dips in the mid-bass region which could be due to positioning and a possible remedy would be to move the speakers so that their backs are closer to the wall. Look into something known as speaker boundary interference Response (SBIR) which would help give more body to the mid-bass. To sum it up, having your speakers too far away from the wall can cause issues in the bass regions.

Another thing worth trying is to change the Target Curve to Harman, which will provide more bass. As I’ve said many times now, the biggest issue to my eyes is above 3K, you may well like it but it hurts my ears to even look at it lol.
 
Wow, 4k onwards looks painful to my eyes. That must be quite harsh on the ears!
This is typical when using a smartphone (Android) and running the room correction on the WiiM Ultra.
Used a UMIK-1 attached to iPad Pro and the results where very different.
Try to make correction only in the lower regions, you will be amazed what a difference it is maken to the whole spectrum when listening

Ahh yes, I use a UMIK 1 myself and didn’t consider that the smartphone mic could be responsible for FR issues. That >3K region needs further investigation though.

My speakers are in opposite corners of the room, and I sit in the middle forming a triangle.
I only used RoomFit to fix the bass (20-500 Hz), leaving everything else natural.
The sound is amazing.
Nick Johnston's guitar is super clear and sharp, and I can hear the music floating in the air between the speakers, not just coming from the speakers themselves.

The wide setup gives incredible stereo though.
 
I've found the Dayton iMM-6 microphone on Audiophonics.fr. Would this be adequate for room calibration? The UMIK-1 costs €100, and since I'll only be using it once, I'm hesitant to spend that much.

Yes the iMM-6C should work just fine. Just make sure you load the calibration file.

An Amazon.us review states that when using the Dayton iMM-6C, the 8kHz peak typical of smartphone microphones disappears.

Oh...you've been using your phones mic? All results are meaningless then.
 
The Dayton iMM-6C measurement microphone has arrived.
I've completed a new RoomFit calibration using its calibration file.
Could I get some opinions on these measurement results, please?

PEQ room correction has the highest potential below ~400Hz, and when applied to minimally smoothed data.

Above ~400Hz, the distinction been direct and reflected sound becomes significant, which your ears can make but the iMM-6C cannot (easily).

Above 400Hz, it is therefore smarter to correct not based on in-room frequency response, but based on anechoic speaker data, or in its absence on gated near field measurements (guide).

Here's a PEQ correction which follows these guidelines:

(Green: raw, Blue: corrected)

Notice how much more detail there is than in your WiiM graph:
Screenshot_20251231_121019_Gallery.jpg

Note also how in the bass, peaks are reduced but valleys are not filled in.

Try to emulate this as close as possible in WiiM Home:

-set Smoothing to the lowest available value

-use the Moving Mic Measurement to filter out irrelevant, hyper local room modes. (For MMM, move the mic slowly to avoid wind noise, attach the pop filter if your mic came with one)

-limit the Equalize range to ~400-500Hz upper, lower depends on speakers' LFX.

-Experiment with different Max gain values to avoid the algorithm boosting bass valleys.

I’ve updated my settings based on your suggestions and tried to interpret the technical steps as best as I could.

Here is what I did:

- Limited the range: I set the equalization to 50Hz - 500Hz

- Smoothing & Mic: I changed smoothing to 1/12 Octave and turned on Moving Mic Measurement (MMM)

- Gain Settings: I lowered Max Gain to 5dB and kept Non-Boost Mode ON

I did the Tidal's sound tests and I have discovered why my WiiM Ultra RoomFit was struggling and why my left Teufel Ultima 40 sounded "flat" and "lifeless".

It wasn't the room or the settings. The tweeter (second driver from the top) is completely dead.

The Proof:
  • WiiM Data: The RoomFit graph showed a total signal loss above 2.5kHz on the left.
  • Isolation: I swapped all RCA and speaker cables; the silence followed the speaker, not the amp or cables.
The speaker has zero physical damage, so it's an internal crossover or driver failure.

I will contact Teufel.de technical support.

Nice troubleshooting. The sudden drop above 2.5kHz was indeed unusual and that would perfectly explain it.
 
Hi everyone and Happy New Year,

I wanted to update you on my search for a new set of speakers.

I’ve officially sent the Teufel Ultima 40 Mk4 back today.

I want to mention that my experience with Teufel’s customer service was excellent so far.

They were cordial and professional in every email. They even offered to send a replacement for a tweeter issue I encountered, but after spending some time with the speakers, I realized I was looking for a different sonic presentation.

They were very understanding and agreed to a full refund.

Now that the return is settled, I am looking for help finding my next pair. I am searching for a "Best Buy" for the buck, strictly under €1,000.

My Setup:
Source: WiiM Ultra
Amp: Audiophonics AP300-S250NC (Hypex NC250NC)

What I am looking for:

I want speakers that are accurate, detailed, and revealing. I am particularly interested in that "holographic" 3D presence where the speakers disappear and you get a deep soundstage with pinpoint imaging. I prefer something with authority and scale, but it must be precise.

I am currently considering:

ELAC Uni-Fi Reference UBR62: I’ve heard great things about the concentric driver's ability to create that holographic image.
( they are currently available on Amazon.it for €755, with the option of 5 interest-free monthly installments.)

I’d love to hear your thoughts on these speakers or any other suggestions (KEF, Wharfedale, etc.) that would pair well with the Hypex's clean power to give me that transparent, 3D experience.

My main listening consists of Jazz, Acoustic Jazz, Jazz Fusion, and Metal.

Thanks!
 
So, I’ve found the ASR recommendations for passive speakers:

 
I'm considering pulling the trigger on the ASCILAB C6B.

I’d rather hear the 'don't do it' arguments or any potential deal-breakers now before the purchase is finalized.

I'm looking for maximum transparency and transient speed, detail and revealing sound.

Specifically, for those who have lived with them: is the 85dB sensitivity a real-world bottleneck for dynamics, and does the 2.6Ω dip pose any actual stability issues for an NCore amp during complex, high-SPL passages?"
