Room correction

And it clearly does. The result still doesn't look good, but that's another story.

The Diamond 12.2 are pretty tiny speakers, but I'd expect them to go lower than what you measured. It's not too unlikely that the problem simply is the iPad Pro mic or the way the WiiM Home app handles its frequency response.

RC adds a massive bass correction in your case. If your setup doesn't sound bass shy (as the measurements imply) it should really sound rather bass heavy (due to the ammount of bass boost, caused by wrong measurements).

Thanks mate ! Tiny but mighty The resulting sound is definitely not very bass heavy - actually considering add a subwoofer. Then I'm also asking myself why I didn't get floor speakers directly, if that makes sense?

Small speakers plus sub can actually be better than floor standers if the amp.offers proper bass management.

The key is that the optimal placement for best low bass response is not ecessarily identical to the best placement for the main speakers. In particular, you can place the sub close to a wall or even to a corner and use EQ or room correction to tame any bass boom that might occur with such placement. This saves amplifier power for the sub and can provide a more equal pressurisation if the room.

WiiM's built-in digital crossover will relieve the small Diamond 12.2 from what they cannot do well, heavy bass duties. So, less thermal stress and less cone movement for their tiny woofers. This lowers the distortion, resulting in better sound.

If you ask me, go for a sub, not bigger speakers.

Cool - thanks mate! I was hesitating due to the relative high cost of the sub-woofer (Wharfedale WH-D10) compared to the speakers themselves, but maybe it is the way to go.

I am also considering adding standers so I have a slightly better stereo separation, as in my current setup the speakers are barely 1m apart. Again room restrictions are playing an important role here. Ahhhh.. it's not easy, but definitely a good challenge

Thanks to the great support from this community and @harkpabst to help me get out of the rabbit hole and proceed to enjoy music

TLDR: Also got the subwoofer, speaker stands and re-arranged my office for much improved placement (but overall office looks less "clean")

My room is weird indeed but I’m trying to make the best of it.

I was expecting the correction to bring the measurements closer to the target line?

I do not think your room is strange, it’s just that speakers are almost never made to measure good in rooms, they are made to have a good frequency response in ”open air” or anechoic chambers.

They then assume that you as a customer will make sure that the speaker you buy ”fits” in your room or that you make it work using absorbents and diffusers if you are not satisfied, or DSP.

Thats why you should always try a pair of speakers at home before you buy if at all possible, they will sound very different to how they sound at the store/dealer.

I had the option of try before you buy, and it was s relief that I got a setup that I enjoy. Now focusing on spending time finding great recordings to enjoy and get a feeling for what I enjoy as a sound.

I’m very thankful for the helpful comments and suggestions. Cheers mate

A little update with Room Correction with my updated setup that now includes speaker stands and a subwoofer that pairs well with my speakers. No matter how I set the cross over, I still get a strange dip just after 50 Hz.

Any idea or suggestion is very welcome.

I’ve attached the reports

What delay settings have you tried?

Which microphone are you using?

 

[FunkeyMunky]

I have used the Wiim to calculate the delay and output latency for the speakers is 4ms and for the sub 5ms

My iPad Pro with the Wiim Amp Pro

I don't think you can have both. It's either or.

My iPad Pro with the Wiim Amp Pro

That probably rolls off at lower frequencies making the dip look worse than it is.

 

[FunkeyMunky]

so 1 ms delay on the sub is the result

Why do you think that? The last one you set will be active.

That could be due to your room, perhaps a large piece of furniture like a couch or similar.

Also what is your cross-over frequency for the sub set to?

In my case, highly unorthodox most likely, I set a "lower" crossover in the Wiim for the sub (70Hz) and enabled full range out to sub, and a slightly "higher" in my sub (80Hz), In my opinion this makes for a smoother transition and it "filled" in some voids without having it "high" enough in the sub to get any sounds that could be positioned (voices or etc.)

It's worth a try, I did before and after measurements with "Housecurve" and it both looks better and sounds better.

I don't know what is causing the 50hz, but I was concerned about the reduction below 160hz. If you are crossing the sub around 150hz, you may need to increase the sub volume a bit more. (Or phase switching.)

I’m all for untraditional approaches. I’ve set the Wiim sub to 78Hz and adjusted the knob on the sub for slightly higher than 78 (guesstimate).
Trying to listen to a few tracks now to assess the updated sound.

What do you mean with “enable full range out to sub” ?

 

[harkpabst]

What do you mean with “enable full range out to sub” ?

Subwoofer bypass mode.

I’ve set the Wiim sub to 78Hz and adjusted the knob on the sub for slightly higher than 78 (guesstimate).

That's unconventional, indeed. The resulting low pass filter slope will most likely be something between 36 and 48 dB/octave then. Unless you enable subwoofer bypass mode.

If you care about that sixty-something Hz dip and it remains, no matter what crossover frequency you pick, then probably the only way to really change this is to relocate the speakers and/or the sub and/or your main listening position. Playing with different filter settings might help, but it's all hit and miss.
