I would be concerned about speaker movement.....
A lot of bass may make them sway while giving no bass at all.
Commercially, many clubs use "all thread" to hang speakers. This is a giant threaded pole about 3/8" in diameter that will mount to the ceiling and speaker with basic plumbing or electrical brackets or with countersunk nuts. If you use several pieces per speaker, it will eliminate the sway.
I would also use a sub to keep the hanging speakers from trying to produce bass.
