About This Product

Auralex GRAMMA v2 Modulation Attenuator

The GRAMMA v2 (Gig and Recording, Amp and Monitor, Modulation Attenuator) 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!

  • A tighter, more focused low-end.
  • Hear the true sound of your amp, loudspeaker or subwoofer.
  • Instantly improve your sound on-stage or in the studio.
