I think I'm going to keep my ancient Pioneer HPM 900s in the exercise room after adding a bit of additional bracing and stuffing. In order to satisfy the wife, I plan to gain some floor space by suspending (or "flying") them from the ceiling beams (its in the unfinished basement, so the beams are exposed). I'd like to do so without drilling holes or otherwise damaging the speakers. They are kinda medium sized speakers, maybe around 20" deep and wide and 30" high, and maybe 40 lbs each. I'd also like to mount them so they are angled a bit downward. Any suggestions on how to approach this?
