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 GreatGRAMMA v2 is optimal for use onstage or in the studio under larger guitar and bass rigs. You get a clearer response from speakers and less low end radiating from the cabinets. It's also useful underneath a subwoofer to give you more definition from your main speakers and cleans up a room's response to low end frequencies. 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 GreatGRAMMA 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 GreatGRAMMA v2 is your key to getting tonal clarity!

GreatGramma isolation platform - I use it under a HiFi stand on wood floors

Pricey for its appearance, but worth the expense. It works quite well as an isolation platform between my HiFi component stand and my home's wood floors. Most recognize that vibration travels across wood floors, and such flooring is not always as flat as one would expect. This isolation platform does the job and can support 300lbs. I've had a micro-bearing filled, Solid Steel HiFi component stand with all components, including a very sensitive, non-suspended turntable, atop this platform over hardwood floors for years now. It isolates, provides a flat, stable surface, and avoids damage to the floors from the speaker spikes and under-spike discs that would surely leave dents if a platform was not used. I use stacked Subdudes under each of my 72 lb speakers, and they work quite well, also.
These are great for placing under musical instrument amplifiers, being flat on the top surface, and highly portable. I recommend these isolation platforms for use under anything in their weight range that needs stability and vibration isolation. These would make great Holiday gifts for musicians and HiFi fans but know the weight range and size required before ordering. Additionally, if you're a musician and live in an apartment, it is your DUTY as a responsible neighbor to isolate your amplifier in some fashion. These will really help, even though you may need to double stack them.
Rated 5/5

These really do isolate and uncouple your cab from the floor sounds much better...

I only had one of these and had my two Mesa 2/12s on the ground, you could just easily tell the cab with the gramma pad sounded better, more clear, just less mud and mush. Got a second one, and truly whether you are recording or live they make a big difference.

Don't Know Why or How, But It Just Works

Don't know how or why it works, but it does. I have all my cabinets and/or combos sitting on one of these. Reduces rumbles, tightens up bass, and just makes the gear sound better overall. It's like that pedal "that just adds something to the sound" and becomes an "always on" part of your rig.

Awesome but I'm using them a bit differently.

Okay I needed something to isolate a mic stand and these do the job perfectly. These combined with the Isovox and I am in home studio heaven.

Auralex GreatGRAMMA

Really awesome and efficient riser, even at high volumes the amp does not resonate hardly at all with the room, it makes great for gettibg rid of that "whoofy" sound when playing metal and greatly tightens up the cabinet itself!
