In my opinion, after using wiim ultra for a few weeks, if you want good sound, you should use room fit to measure the room's acoustics and use the graph results as a standard. Next, I set the db and Q, Gain of roomfit to default because I prioritize EQ first, I adjust the EQ until I hear the clear sound with all the bass, mid or treble frequencies that I like, then I adjust the EQ of room fit to compensate for the frequencies where the sound has not reached the purity, vividness and sparkle, and here are some of my wiim home settings to share with you to experience!
