Auralex Great GRAMMA Amplifier Isolation Platform

The Auralex Great Gramma (Gig and Recording, Amp and Monitor Modulation Attenuator) is an incredibly effective patented device that's used to float an amp or loudspeaker.

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

Great Gramma yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed!

Now 4x12s, 15-inch or 18-inch speaker cabinets will benefit from the awesome Great Gramma.

The Auralex Great Gramma Story

The original Gramma solved a major problem with speaker cabinets in live and studio situations by acoustically decoupling the box from the floor or stage, effectively cleaning up the sound. Auralex developed the Great Gramma based on industry requests for a system that can handle larger cabinets. Their engineers designed the Great Gramma to provide the same isolation specifications, while offering a larger footprint for bigger speakers.

The original Gramma is 23 inches long by 15 inches wide and 2 inches high. The Great Gramma is 30 percent larger offering an isolation platform that is 30 inches long by 19 inches wide by 2inches high and exceeds the 300-pound weight limit of the original Gramma. The system comes complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath), and PlatFoam (underneath).

All gigging musicians are faced with a voicing problem between the instrument amplifier and the stage floor. When a note is played on the guitar, bass or keyboard, the speaker cabinet vibrates and, in turn, so does the stage, effectively muddying the sound of the cabinet. Worse, the stage can vibrate the mic stands and its microphones, creating feedback situations. The Great Gramma completely obviates this situation for the larger cabinet.

While the live applications are obvious, the studio applications, especially in the home or project studio, are critical candidates for Gramma treatment. In this day of extremely high quality digital recording systems available to everyone, creative tracks are routinely recorded by top professionals and hopeful stars alike in less than controlled acoustical environments.

These tracks often show up at a large studio where a project is completed. The Gramma and the Great Gramma, with their excellent isolation specifications, help artists record sonically honest tracks that reflect the true sound of their instruments without the coloration of the compromised acoustic environment of a living room or basement studio. This purity is reflected in tracks that deliver the emotional content of the performance without resorting to an equalizer to reshape the sonic quality.
