Hi all,

First post here so hi everyone!

I’m renovating and putting in a home gym which will also double up as a cinema room & golf simulator. My room is approx 8m x 5m and I’m looking to put in Sonos speakers so that I can listen to music when using it as a gym but then also have speakers that would work well enough when using as a cinema room.

Ideal situation is that I have one speaker set up that works well for both so I was thinking one of the following options but am not sure if they would work. So I would love some feedback and I’m open to other suggestions.

1. 4 ceiling (or other type) speakers: Could this work as surround i.e. two for rear left & rear right and then two for front left, front right & centre? Does a pair of Sonos split right and left and can two Sonos also incorporate centre as well as front and right?
2. Soundbar plus 4 speakers: Whilst I’m pretty sure all cannot be used together (is this right), if I had a soundbar and 4 speakers, would I be able to use the 4 speakers e.g, for music and then for films, just switch to the soundbar and the two rear speakers?
3. Soundbar plus 2 rear speakers: Does anyone think music will sound odd with this set up when using it as a gym?

Regarding soundbar and size of room, would an Arc be overkill for a room of that size and would a Beam be sufficient?

Also, I’ll have a TV and a projector in the room so can both be connected to the same amp/soundbar (I’m actually not sure if I connect to the sound bar or amp or both) and if so, can I easily switch which device I want to connect to the speakers? 

Finally, when ceiling mounting speakers, does any sound travel up into the room above? This room will be under a bedroom and so I don’t noise spilling upwards during early morning gym sessions or late night movie watching.

Thanks all!
