I'm in the kitchen business, and we do our granite counter tops "in house", with NC equipment. Over a period of time, we accumulate lots of material left over, and it suddenly dawned on me that it might make a great material for mounting speakers. The material we use is 3cm, and can easily be cut to any size with hole drillings for speaker mounting screws (with threaded inserts), along with any specified radius, etc. Would there be any interest in this?
