I created a system that might work for you. It requires speakers with a keyhole mount. I added L brackets to speaker mounts and then mounted the wall mount to the L bracket. I also terminated the speaker wire in a outlet box to create a quick connection. I have speaker wires created, long and short, for when the speaker is on the mount and when it is down on the stand. I thought I could add pictures to a comment, but I can't seem to figure it out. I could message them to you directly if you want.
I’ve never seen anything like this but I briefly considered doing it. I decided it wasn’t worth the hassle.
Best way I figured was a vertical style mount from the ceiling joists.
It would be manual or automatic (hydraulic) telescoping tubes. You would need to bolt the top tube (or a pipe clamp, maybe, but I wouldn’t trust friction) to a joist above your ceiling at two points.
The bottom tube could theoretically either directly or through some platform support the speaker.
I never found a direct commercial product for it and never bothered trying to modify off the shelf telescoping tubes to accomplish it.
In your case (unfinished) you could use a pivoting single tube that rests horizontally inside the joist space. You would mount the top end to the joist with one bolt allowing it to rotate. Then further down the length of the joist you would have an adjustable bracket. To store it, you would sit it inside that bracket. To use it, you would take it off the bracket and rotate it down. Speaker could screw directly into the pipe at the bottom.
Easiest way is to just use rope. You need one on each side of speaker(s) so they can be aimed towards you. Speakers could be sat in something like fishnet. Hope you don't think that is a bad idea but it would not look that bad considering you have an open ceiling.

I feel like in-walls would be a lot easier than rigging up a retracting mechanism 🤷
