Sub isolation platform dilenma. DIY?

[selkec]

SO I just bought the Craig Sub 18.1 "The Mono" It is 20x20 20
The Auralex great Gramma is only 19" wide
The Subdude is only 15x15 So neither will work. What do you all suggest? Get 2 of either of them? or is there a cheaper alternative. Maybe a diy route as I like to try to make things anyways.

Even though the sub is 20" wide, the feet may be spaced less than that. If so, you may still be able to use the gramma but the sub will just overhang 1/2" on each side.

So, I rested a thirty pound gray paving stone on a 14 yellow tennis balls to create my own vibration isolation platform and I did indeed notice a pleasurable change.

Imagine setting a gallon of milk on top of a carton of eggs. Incongruous perhaps, but the result is solid and stabile – it does not shake or sway.

I set an 18” by 18” Yorkstone slab ($3.50 at Home Depot) on top of new tennis balls ($10 at Wal-Mart). The balls rest on a thin sheet of foam board (old poster board) to form the bottom of the platform. The board, or a sheet of plastic, makes the platform easy to slide around on my entertainment center. A simple 1 ¼” wood frame corrals the balls. Although constructed for a dozen balls, there is room within the frame for 1 or 2 more balls.

Each ball is a small rubber air bladder. Tennis balls are larger and cost less than racquetballs – though racquetballs may hold up better in the long run. A low box would do as well as the simple wood frame; as long as the paving tile does not touch the box. The dense slab must float out and above the tray of balls like the elegant cantilever of a Frank Lloyd Wright house.

Slab of granite with hockey pucks as feet

I have a wood floor so the hockey pucks probably wont be a good idea. I found one from the elemental designs site that will fit.

Hockey pucks are just hard rubber so they shouldn't damage a hardwood floor.
