Get Cleaner Sound from Your Amps and Speakers The Auralex GRAMMA (Gig and Recording, Amp and Monitor, Modulation Attenuator) is an incredibly effective patented device that's used to float an amp or loudspeaker. The GRAMMA yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed. When speakers or amps sit directly on the floor, they create structural vibrations that travel back through them. This can cause the output from the speaker to sound muddy and lack definition. View larger . Floating the amp or speaker on the GRAMMA eliminates these vibrations, which helps improve the overall frequency response and clarity of output. The result is tightened response across the board, especially in the lows and low-mids. Once you use the Auralex GRAMMA, you will never put your amp on the floor again. Auralex GRAMMA Features at a Glance Rugged design for studio or live use Decouple your amps and speakers from the floor Supports most amps, speaker cabinets, subs, and monitors Dimensions: 23 x 15 x 2.75 (Inches L x W x H) Get Amps and Speakers Off the Floor The GRAMMA amp and speaker isolation riser is fabricated using patented Auralex PlatFoam. PlatFoam is a thicker, denser variation of our industry standard Studiofoam that is very effective at controlling low-frequency vibrations. With this material between your amp and the floor, you can achieve almost total acoustic isolation. This translates into a tighter frequency response across the entire broadband range, and is most noticeable in the low and low mid ranges. View larger . Rugged Design for Studio or Live Use The GRAMMA platform is covered in rugged Ozite, making it able to stand up to the wear-and-tear associated with touring and regular gigging. View larger . Supports Most Amps, Speaker Cabinets, and Monitors With dimensions of 23-inches long, 15-inches wide and weight limit of 300 pounds, the GRAMMA is sturdy enough to support most 2x12 and 4x12 amp cabinets. The dimensions are also ideal to isolate dual-15-inch speakers and most wedge monitors. GRAMMA comes complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath) and PlatFoam (underneath).
