>>I guess you could always use bungey chords or duct tape.

Bungee cords seem to be more "politically acceptable" -- you can always say "it's a Jolly Jumper". Using duct tape to keep your kids away from the speakers is frowned on in some states.

Oh wait, maybe you were talking about fastening the speakers to the stands. Never mind.
