You are foing quite off topic guys

..This thread is to gather user feedback on Ultra's beta firmware feature "Subwoofer Calibration". I am afraid
@WiiM Support @WiiM Team will need to struggle to find among dozens of messages the 3 or 4 messages which really provided the feedback this thread was intended to collect...
On the other hand i am starting to doubt they really read the thread since no messages posted, no responses/clarificarions provided to users who already tested and wrote results/feedback posts. Maybe they just gather user logs from the wiim home app from those users thar have the beta installed... Although i would enjoy and probably would be more productive to have some more interaction with them.
