Acoustic ceiling panel help

[simplyme]

How have you guys with panels on the ceiling hung them?

I have been recommended Beau Clips but wanted to check if anyone has any other suggestions?
My panels are made out of 9mm plywood, 2" foam, faux leather cover and are 23.5" x 40"
The ceiling is plasterboard

Thanks

I used spray adhesive to stick mine to a 4x8 sheet of 1/4 inch plywood and then screwed the sheet to the ceiling through the drywall and into the studs.

I used mounting plates at the front into the studs and French cleat system at the back and for the side panels in the end, solid as a rock without breaking the leather
