I have not, but according to Google, it should be pretty seamless. If you already have this speaker and can see it in the WiiM Home App, you should be able to see the bass management options now, which should be similar to - if not the exact same as - this functionality for other WiiM devices, which I found to be mostly intuitive. Definitely easy to set up and tweak to get a perfect balance. I don’t know how the bass response is on the C10, but I’ve yet to see any speaker that hasn’t benefitted from adding even a small sub. I had a pair of Alesis 3” powered monitors that I ran off a Cerwin Vega 8” sub for my digital piano, and the sub really woke up those little cubes. I’ll bet you’ll see some nice results, but I’ll defer to someone who’s actually added one.
