Acoustics are often the biggest influence on an audio system’s performance, no matter if it’s a home theater setup in middle America or on stage in Madison Square Garden.

Auralex‘s newly updated GRAMMA (Gig and Recording, Amp and Monitor Modulation Attenuator) line of acoustic isolation platforms can be used in residential and commercial environments to decouple speakers, subwoofers, monitors, guitar and bass cabinets from harmful vibrations and resonances that negatively affect performance.

The Indianapolis, Ind.-based company points out the V2 series utilize Ozite cover over a structural layer that “floats” a 1-inch pad of Auralex’s Platfoam material. This combination of materials allows the true sound of a speaker and amplifier to show through without resonating artifacts.
