Auralex Gramma Amp Isolation Pad

Musicians spend good money on amps/cabinets/monitors but sometimes the floor itself works against them. Speaker cabinets can interact with the floor, resulting in a loss of intelligibility. The GRAMMA is an incredibly effective device that's used to float an amp or loudspeaker and yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed! GRAMMA comes complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath) and hi-density PlatFoam. 1 or 2 GRAMMAs (23 x 15 inch) will support most amps, speaker cabinets, subwoofers & monitors weighing up to 300 lbs.

The GRAMMA is an incredibly effective device that's used to float an amp, loudspeaker or subwoofer and yields nearly total acoustic isolation. The result - a purity of tone that has to be heard to be believed!

zZounds is an authorized dealer of Auralex products.
Dimensions (L x W x H): 23 x 15 x 2.75"

Weight Limitations: 300 lbs.

Customer Reviews
4.5 out of 5 (19 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Best $50 Investment for Your Bass Sound"
Sound: Tightens up the lows in my bass rig. All the low-end tone is there, but the boominess is gone. Feature: N/A Ease of Use: Set your speakers on it -- that's it. The size works great for my GK Neo cabs, but traditional-sized 4x10 cabs will need two or the larger unit. Quality: Seems good, but we'll see how it travels. Value: Sems pricey for what it is. But I looked into making it myself, and I came up with about $30 in materials. Manufacturer Support: N/A The Wow Factor: There is no "I want it" appeal about this other than the great sound. Overall: Great bass sound.
Style of Music: Alternative

zZounds has verified that this customer bought this product from us. "This really helped!"
Quality: This is very well built. I bought mainly to stop the sound vibrations from my amp from going to the apartment below me. It works great! As a bonus it makes my amp sound much better too. Value: Great value for the increase in sound quality and vibration limiting. Manufacturer Support: Have not had to contact company, but I know Zzounds has awesome support. Overall: I expect to have this item for a long time. If it was stolen I would buy a new one. It really helps keep the vibrations from going through the floor and it helps the sound of my amp.
Style of Music: Rock, Blues.

1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today. While our competitors might offer house credit cards that require you to fill out an application and pass a credit check, our payment plans are easy to get, simple to use, and, best of all, accrue zero interest. Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
