I don't know whether it was on here or another audio site but I was inspired by the DIY sub riser someone built with slabs of granite. By a stroke of dumb luck a new employee at my store has a part time job at a marble and granite shop. With this, he said they throw away plenty of scrap in the size I need to put under my sub 12s. The place I saw the original riser with the granite sheet used hockey pucks as the feet and I was thinking of doing the same. However, via parts express there are plenty of rubber cabinet feet to choose from at little cost 60-75 cents per.
With these options in mind does anyone have recommendations as to which would be better? I think the hockey pucks would possibly work better but look worse. The rubber would be thicker, heavier, and have a flatter surface for supporting the 3cm heavy sheet of rock compared to the other feet available. However, the option of very cheap rubber feet from parts express would allow me to buy more of them and place them in say 6 different pressure points.
The last part of all of this is attaching either the pucks or feet to the granite. Any suggestions for an adhesive to use on either one of these things?
Thanks for the help.
