Don't know if this has been discussed on this forum, but I would like some advice on suspending speakers on retractable poles. My 20 x 20 games room/bonus room has both RPTV and my son's desk/PC on opposite walls. I need to get speakers to the rear and sides (7.1) of the two couches that sit in the middle of the room facing the TV. I don't want the clutter of using stands and wires across the carpet, so I thought about hanging the speakers from the ceiling using threaded poles and the round enclosures that they screw into. Then I thought rather than have them permanently hanging down just above head height, it would be better if I could make them retractable. I have a spare garage door opener and some pulley blocks that I could modify and place in the attic to move the speakers up and down using a remote. I could even have them disappear into ceiling recesses when they are retracted. My question is what happens to speakers when you suspend them on the end of 4 foot poles? Would they vibrate and move too much in use? (All four rears are Yamaha 333's). Would I be better having wire cables to eyes in the top of each speaker thereby making the mountings less "rigid"? Is it even a concern given the output of the "presence" channels?
