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
