Hello highend666. Granite/Quartz countertops are frequently broken during transportation and installation. Broken bits can be had for very low prices and the shops that have them will cut them for you. I have made seven cabinets out of broken counter tops. You can make the fronts out of any kind of wood product you like, the backs too. Glue the countertop pieces together with construction adhesive or silicone rubber. Heavy, but acoustically inert.

Could concrete speaker enclosures give us the most realistic sound ?
