I’ve preordered the Arc and Sub; I have a few questions;
1) I have 2 Sonos Play 1s as rear surrounds. Will these be compatible to pair with the Arc and Sub for a surround system, or are only Sonos One/One SL compatible?
2) I have an LG OLED C9; is HMDI eARC the best way to connect audio? Should I use an HDMI 2.1 for this?
3) I have a frame around my TV; if I mount the Arc directly under the frame, it covers the top of the speaker: would the acoustics be better if I mount a wood box behind the Arc, so that there are no obstructions* on top of the speaker?
