Beam (Gen 2)
Compact value, but virtual Atmos and app issues.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
The Ray is very much a budget soundbar while that JBL, at least back in its day, was probably closer to a mid range bar. Without a sub the Ray will likely be underwhelming in all respects compared to what you have. Beam Gen 2 will at least give you access to newer audio codecs and simulated Atmos.
I bought and am returning the ray, the sound is awful ! Worse than a cheap refurbished Panasonic unit I had !
Personally, for what you've described, I'd go with another Move 2. That's what I use when we bring the projector out to the backyard for movie night. But Play would also be a good option. What's the source you're playing from on the projector? If you're using an Apple TV or Mac laptop, you can also use AirPlay as an option, which would allow you to use one of the soundbars (Arc Ultra, Beam gen 2, or Ray) instead. If it has to be Bluetooth, Arc Ultra would work as well.
Sonos Ray is the cheapest way to plug a TV into the system.
Yup. You can always set the Ray volume to 0 and just use the Amp, but at some point you can just use the Ray to not make that much noise. If you have home automation, you can do this automagically.
This is how I do it and I don’t notice a delay
I have an older Sonos Ray with only an optical connection. I can adjust the volume with the tv remote just fine.
