The racquetball platform dates back to around 1980, I use to make them using pieces of slate I bought from a company that made pool tables. This works even better than plywood but I have no idea what it would cost today. I recently made one with a large maple cutting board and it worked well. What we always did was to deflate the racquetball by making cuts in it as it was too bouncy otherwise.
Racquetball isolation platform perfection
Racquetball isolation platform perfection ... and DIY style to boot ! Thought I'd share with you my experiment that turned out working perfectly in my system.
Basically I copied a Ginko Cloud platform using $5 worth of racquetballs from Wal Mart and some 1/2" Birch plywood. I used a specialty grinding stone from a local tool store that makes a perfect 1.5" concave in the wood. Cinched it up in my drill press and drilled it down about 1.5" in from every corner, and went down about 3/8" deep. It's allows the balls to move back and forth by about a half inch, and when the top platform is added the CD player simply " floats " on top. just like an original Ginko. This EASILY bested several different cones I have in my collection, a set of Isonodes, a set of Symposium Rollerblocks, and a innertube isolation platform.
Total cost ? $15.
The bass is the tightest and most defined I have ever had in my current system. It made amazing amounts of good things happen under my Lexicon RT-20.
Try it for yourself, it was a winner in my system.
