Love the hockey pucks. Muck like @insearchofprat, I am using balls - albeit street hockey balls. (when in Canada...) One on each corner, I cut "donuts" out of MDF, plopped the bright orange street hockey balls into them, put speakers on top and they work quite well! Was concerned about using tennis balls as the speakers are just over 100lbs. Thought about a LOT of racket ball balls, but didn't feel like having to cut out all those holes for them
Next, I'm going to try a spring loaded platform to see what if any benefit can be had.
