Question - is there any option now to use two WiiM sub pro:s in stereo , through WiFi ? It seems that the dsp processor in the Wiim ultra is more transparent sounding than the Minidsp hd , so if Wiim could make stereo in the bass an option through WiFi it would be great .

The best thing with this Roomfit function is that we in practice have 20 peq bands to play with, combining EQ with Roomfit, with both turned on. This gives us a very nice opportunity to fine tune everything, but also measure from psychoacoustic correct distance with the microphone. One can use...

Ah, ok then the algorithms are possible improved .

It’s fantastic how WiiM keeps developing better software . A further enhancement in soundquality could be if they would be offering 5th order LP/HP crossover ( 30/30 or 30/18dB for using with closed main speakers .) You get a slighty better power response in the room this way compared to...

Thanks for clarifying dominikz, and thanks EddNog for showing an example of use. Just tried the new roomfit correction very quickly and the sound is kind of clearer than before, even using my iPhone 14 as microphone.:) Looks like WiiM are doing the math-crunching in the cloud, possible...

It’s important to know the differences between fundamental room resonanses ( wall/wall, floor/ceiling, wall/wall ) and reflections . Many misunderstand this. The fundamental room resonances are mainly 3 of them - entirely dependent on the size of the room. They are all below 80 Hz in a normal...

As dominikz already wrote, the scale of those measurement is 300dB . Standard is to use 50dB. If the measurements of the different microphones are done at exactly the same spot ( I doubt it ) , the differences between the different microphones are huge. Best way to have better sound using the...

The option to go stereo is very interesting and will be an improvement .

The jitter performance is a little better using the Ultra. This can be verified by several measurements. With my external Rega dac R I can hear a very very small advantage with my Ultra compared to my WiiM pro. The small differences can be heard in the stereo image. The sound advantage using my...

Some unorthodox trick: Try using correction settings 100 Hz - 4000Hz . Harman target, 1/6 dB smoothing. This way , you have nice corrections at the very sensitive 100-600 Hz area ( including SBIR ) but none at all in the bass. This might give you a good result that you like with more bass. The...

Onlyoneme - can you please do measurements of 32 multitone IMD at toslink input for the WiiM Ultra measured after the inbuilt dac at the analog RCA output, test signal done with 44.1 kHz sampling . And a frequency response measurement with the same 44.1 kHz ? I would like to see if the toslink...

Lots of people don’t realize the greatness of Wiim products . They don’t do sample rate conversion . This is a great advantage for soundquality, making it sound meatier, more natural and less digital than the average audiophile streamer transport doing SRC. This soundquality advantage for the...

I have done some testing …. https://www.diyaudio.com/community/threads/wiim-ultra-who-has-it-and-who-has-already-opened-it.417905/page-9 I had to try …. USB out from the Ultra , to my DDC with precision clocks and spdif to my rega Dac R . No sound difference compared to Ultra - spdif -...

I hope they read our request :)

A 4th order crossover like the one thats already used in the Ultra for subwoofer and the main speakers are good, but a better power respons in the room below the transition area can be had with an odd order crossover like a 5th order low and highpass filter. Thats 30dB/oct slopes. If the main...
