Product Description

We all spend good money on our amps/cabinets/monitors but sometimes the floor itself works against us. 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.

The GRAMMA is an incredibly effective device that's used to float an amp, loudspeaker or subwoofer and yields nearly total acoustic isolation. The result - a purity of tone that has to be heard to be believed!

What are people saying about the new GRAMMA?
Auralex products are unchallenged both live and in the studio. I love Auralex's new GRAMMA. Onstage it really smooths all my guitar tones. In clubs, theaters and even outdoors, the GRAMMA really makes a huge difference... The production crew of Tower of Power was so impressed, they started using them underneath the horn section monitors, the keyboardist's LESLIE speaker and several drum mics... FANTASTIC results all the way around.
Jeff Tamelier, Guitarist, Tower of Power

...Low end much more focused. I was able to dial in exactly what I wanted, w/out room resonance's.

My two recording amps stay on the stands. If we switch amps, they go right back on the stands.

All the little buzzes & rattles normally in a room go away immediately.
Lee Roy Parnell, Vanguard Recording Artist

Awesome... made all the difference in playing small rooms... Cleaned up my sound... I now enjoy my full volume tone at lower volumes.
Benito DiBartoli, Blues guitarist

Low Frequency Drum Resonance Isolation... What a concept! I recommend the PlatFoam for any drummer who needs to eliminate complaints from the neighbors or family members. I would also highly recommend it for studios that want to prevent low frequency resonance bleed. The PlatFoam is simple to use, simple in concept and is simply amazing!
Dendy Jarrett, Nashville Drummer/ MusicPlayer.com's Drum Channel Editor

Your general opinion of this product.
I could not get the tone I wanted from my Marshall combo amp at church. Then I started reading about bass amp coupling, where the sub-frequencies get absorbed by the floor in some settings like a hollow stage. Bought the GRAMMA, slipped it under my amp, and WOW! My amp sounds like it should. Stop fiddling with knobs and changing strings, your problem is not your gear, it is the floor!
