Roughly 30 by 30 feet? You could have listenable background level music with a Play 1 in each corner, if you want louder then going to Play 5s might be necessary. Adding one or two Sub systems would give you a lot more low frequency sound if you want that.



Make sure you understand how multiple users work with Sonos and Spotify (I don't but have seen it mentioned here) to make sure it meets your needs.

Hi plante 14



Taking Stanley_4's advice (a step further) you might consider BT using Sonos. Here are the scenarios:



Advantage in either scenario

1. Users do not need the Sonos app nor access to your network



Scenario 1

1. Play 1's x 4_each named separately or 2 x 2 in stereo pairs

2. Sonos Connect (named as a room)

3. Bluetooth transmitter/receiver connected to Sonos Connect RCA or Optical out

4. Group the Play 1's to Sonos Connect



Scenario 2

1. Play 5 x 2 or 4_each named separately or 2 x 2 in stereo pairs

2. Bluetooth transmitter/receiver connected to Line-in of a single Play 5

3. Group Play 5's
