Hello. I have wiim ulta connected with topping e70v and fosi za3 as monoblocks. From wiim i have also connected svs sb1000. Everything worked fine. Nice bass from sub perfectly adjusted to speakers loudness with crossover 100hz, I even checked that with 20-20khz sample and microphone. From today sub lost his loudness. It is not working, or maybe working a little when i put volume to max. I checked sub with yamaha amplifier and works totally fine, connected directly to fosi also works. It seems like FLE outup in wiim broke. I reset wiim and didnt help. Any suggestiosn before i sent it to warranty?
 
Welcome.

Quite possibly a silly question, but have you checked the subwoofer settings in the wiim app just in case they have changed?
I'm assuming that "I reset wiim and didnt help" most likely means you went back into the settings afterwards.

You could sent feedback via the app for wiim to check device logs in case they contain anything pertinent.

Of course I checked sub settings and everything should be working. Sub turn on in app, crossover set to 100hz and on saturday it worked well. Now sub is working a little when i set volume to 70%.

I already sent a ticket via app and waiting for feedback from wiim team but thought that somebody had similar issue.
