After buying Beam and sub mini from SMS I was undecided if to go with the 100s or 300s. My lounge is about 20 sq meters so after many weeks of research and speaking with SHS customer services, I decided to go with the 100s. I’m really pleased with the choice, the sound quality is better than I thought it would be from such a small speaker. I have them set up on the wall either side of the settee and hid the cables behind the wall. Overall customer service and quality of the sonos product is excellent.
