We currently have 2 QS8s being used for rear speakers, M60ti for fronts and a VP150 for center. We want to add 2 surrounds but the problem is the room is part of an open floor plan so the wiring is on the ceiling. We don't want "in-ceiling" but we need "on-ceiling" mounting. There is no way to wall mount the surrounds since there aren't "walls" available.

Unfortunately, I don't know how close to studs the wiring is since it was done prior to us moving in but I suspect there will be suitable mounting options for brackets of some type.

Suggestions?
