Auralex GreatGRAMMA Speaker Isolation Riser

The GRAMMA (Gig and Recording, Amp and Monitor, Modulation Attenuator) is an incredibly effective patented device that's used to float an amp or loudspeaker. GRAMMA yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed!

Built on the success of GRAMMA, the Great GRAMMA is almost 30% bigger to float large speaker cabinets.

Now 4x12s, 15" or 18" speaker cabinets will benefit from the awesome Great GRAMMA.

Comes complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath) and PlatFoam (underneath).
