Hi.  It seems extremely unlikely to me.  I cannot think which wireless protocol it would use.  But obviously that doesn’t mean it cannot be done…. maybe I have missed something.

Generally speaking, the answer to any question that comes down to “Can I use Sonos speakers that are not designed for AV use as AV speakers?” is either:

“No, use a Sonos device that is designed for AV use”, or

“Yes, but it’s a bad idea, use a Sonos device that is designed for AV use”

I believe the first of these answers applies to your question. If it doesn’t, then the second answer applies.

Hi John

thank you. I think you may well be right. I have a play bar too but wanted to Crete this wirelessly. Is there a way to pair the two moves via blue tooth to the projector? 1 move pairs perfectly and gives great sound but wanted a better cinema experience. 

There may be some third party software that allows you to play to two Bluetooth devices but that would be a job for Google - it isn’t something I know much about.

What source(s) are you playing and how do they connect to your projector?

Hi john

at the moment I have an Amazon fire stick in the hdmi port on the projector and blue toothing sound to the move. It works well but just want it boosted. I understand from Epson that the projector won’t accept 2 bluetooth speakers at the same time even though their tech sheet shows 2 speakers communicating with the projector… 

On android phones, you have the ability to send audio via bluetooth to two separate speakers/headphones.  I’ve done this with a pair of Roams.  However, it’s not a stereo pair, each speaker is playing mono.

There are a lot of ‘bluetooth splitters’ available on Amazon, that appear to take audio from a headphone connection and send it via bluetooth to 2 or more speakers.  Again though, it does not look like it can send left and right channels independently, but I didn’t take a look at many of the options.
