collapse expand iconDescription

The Auralex GRAMMA v2 (Gig and Recording, Amp and Monitor, Modulation Attenuator) isolation platform is an incredibly effective patented device that’s used to float an amp or loudspeaker. This highly effective isolation platform features an Ozite covering over an inert structural layer that floats on a 1" pad of acclaimed Auralex Platfoam. This carefully engineered studio and live performance solution allows the true sound of your amp or loudspeaker to come through by negating resonance artifacts that can muddy up the tone of your amp.

GRAMMA yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed.

    Very effective isolation and dissipation of unwanted resonances especially in the bass region which is exactly what I got it for.

    This made all the difference with a very noticeable improvement for our 1x15 bass cab. Punchier and a more defined , accurate sound was heard and felt immediately. I was skeptical but once tried I will always want this for low end cabs.

    I bought a JBL LSR310s subwoofer to compliment my studio monitors LSR308. I couldn't really get them dialed in; as I increase the output from the subwoofer. The hardwood floor it was on would resonate the frequency and frankly was diminishing my ablility to get a flat response in my listening area. I placed the GRAMMA under the subwoofer, and voila!; no more resonance, just sweet low frequencies enveloping me, instead of just my feet. It's a bit big for my subwoofer, about 2-3 inches stick out of each side, but I'm ok with that.
