Auralex GRAMMA Amplifier and Monitor Isolation Platform

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

Subject:Works Great For Me
Quality: This is a really nice product. I'm surprised they can sell it for only $50.
Reliability: I set my 75 lb bass cab on it and it didn't bow, so I tried sitting on the cab (I weigh 200 lbs) and the Gramma could handle it just fine.
Overall: My recording room is sympathetic to A. That means when I played a low A note the whole room would rattle and quake. Problem solved.
Playability and Feel: Don't expect this to cure every problem, the Gramma is only one important part of the solution. Use the Gramma in conjunction with poper room treatment for best results. Don't rely on foam traps, get ones constructed from rigid fiberglass board like the Ready Acoustics Chameleon bass traps or similar for best results.
Tone: Tightened up the bass and decreased the "mud".
Finish: Looks great
Action: N/A
Skill Level: Semi-Pro

Subject:I could live without it.
Quality: The product seems well made. It looks very nice out of the box.
Reliability: I have only had it a few days but it already seems to be bowing underneath my amp. It is rated to hold up to 300 lbs but it is having trouble with my bass amp which is nowhere near 300.
Overall: Overall I am a little disappointed. I really hoped it would help when playing at slighly louder volumes to eliminate some of the room noise (as advertised). It really did nothing to help.
Playability and Feel: ?
Tone: I really did not notice a great difference in tone. I played my rig before I put it on it, then I played it after. A little (I mean little) less room-noise but nothing spectacular. I suppose it is not made specifically for basses but they advertised like it would make a great difference. I could easily do without this product.
Finish: Again, very nice.
Action: Fine.
Skill Level: Intermediate
