Better Sound for Studio and Stage

Clarity - get it with Auralex's GRAMMA v2 series isolation risers. You've invested time and money in finding the right gear, so take a step towards getting the clarity and definition you need, be it from your studio monitoring setup or your favorite tube guitar amplifier. Using an isolation riser decouples your sound source from its surroundings, preventing low end waves from traveling through floors and walls, muddying up your sound, and masking the frequencies essential to sonic definition. Don't second guess your gear choices, get the clarity you want by putting an Auralex GRAMMA v2 isolation riser to work for you and your sound!

The GRAMMA v2 is optimal for use onstage or in the studio under guitar and bass rigs. You get a clearer response from speakers and less low end radiating from the cabinets. It's also useful underneath floor monitors to give you more definition for vocal monitoring. No matter what you put on it, isolating sound on stage means you can keep the volume lower, so you'll have less feedback and stage noise to deal with.

Auralex GRAMMA v2 Isolation Riser Features:
  • Better mid- and low-frequency definition for clarity
  • Isolates your gear from the floor to stop low end rumbles
  • Gives you nearly total acoustic isolation for better tone
  • New easy-grab handle for easy transport
  • Road-ready carpet durable and rugged for years of use
  • Lower profile for increased stability
  • Supports most amps, speaker cabinets, subs, and monitors

In the studio or on the stage, the GRAMMA v2 is your key to getting tonal clarity!

Great buy!

I bought one of these years ago at a friend's suggestion. I was in a band with six other people and no matter how my monitors were my guitar would get lost in the stage noise. PROBLEM SOLVED. I put this thing under my amp at a gig untested and heard every note I played that night and so did the band. I even noticed in small venue situations, where I needed to set up close to the drummer, it even reduced his snare wires from rattling when I was the only one playing. It solved so many sound problems onstage, in the studio, and in rehearsals. Get this thing if you like to hear your self play. Great for bassists too!

A great improvement

A bass player's friend: removes a lot of the wolf tones, boominess and inconsistency from less-than-perfect stages and rooms. I used one of these on a stage where it was provided by the sound company, and thought, wow, my rig sounds clean and defined. I went home and home-made one, using a stiff closed cell pink packing foam. It helped, really quite a lot. But I finally ordered the Auralex real deal, and it's better. The foam choice is mushier than my home-made pad, but oddly more stable. The flattening and de-mudding would surely carry to floor wedges and subs, guitar amps and oh, under keyboard amps for sure, which are famous for erasing the bass player's sound. My current rig is a Fender Rumble 200V2 and the matching 12" extension cab. The stack probably weighs 75lbs, nowhere near the pad's 300lb limit. This is a fine product... five stars. You will sound better.


This small detail piece of gear makes an amazing difference in "controllability" of the sound of the amp. Without one, you are at the mercy of the layout of the room and any surprise unwanted resonance. Think of what a clothes dresser sounds like if vibrating! This one piece of gear goes a long way to eliminate noise and vibrations from the space you are in, so important in home studio applications. Try one!!!!

It really works!

For years I would get so frustrated by my bass guitar notes disappearing on me from one room to another etc...I tried one of these and what a difference my frustration is gone for the most part. Now my band uses these under the subs for the sound system and our lead guitar player has one to. It removes the mudd and help my bass notes to ring more even. Try one for yourself

Great Quality Product!!

Amazing Acoustic Stage!! does the job exceptionally well. You can actually notice the difference in sounds with and without the stage. as always my Good Friends at Sweetwater Shipped it very quickly and like always their Quality Products and Packaging never Fails :) Special Thanks to Ryan Wiltermood!!
