Hello Ed, I'm very interested in these little soundpad-buggers. I picked up a couple of pair and have been playing around by sticking them to foamboard and the walls with duct tape so far. Is there any internet wisdom for the layman out there about using these little guys as invisible home theatre speakers..? Behind the drywall.. on top of the drywall.. two pads per channel to help handle the power from a 100 x 5 receiver.. etc..? I only ask because my wife does not want to see any speakers anywhere if we can avoid it. Thanks!
