I have an issue with R-10B.
I used to play the audio over Bluetooth, but for some reason it would skip/freeze every once in a while. Especially when someone walks past the soundbar (large adult). I figured it was due to bluetooth being week, so resolved to putting my phone right next to the soundbar to get uninterrupted play. However, when I got fed up with that, I've gotten a fiber cable and plugged it in to play the sound. And still i'm getting strange stutter/freezes.
As soon as I moved the subwoofer away from the fridge, it stopped skipping.
