Musicians spend good money on amps/cabinets/monitors but sometimes the floor itself works against them. Speaker cabinets can interact with the floor, resulting in a loss of intelligibility. The GRAMMA is an incredibly effective device that's used to float an amp or loudspeaker and yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed! GRAMMA comes complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath) and hi-density PlatFoam. 1 or 2 GRAMMAs (23 x 15 inch) will support most amps, speaker cabinets, subwoofers & monitors weighing up to 300 lbs.
