Serious Upgrade for Your Speakers

From heavy amps to full-sized PA speakers, the IsoAcoustics plus-sized ISO-Puck delivers the acclaimed acoustic isolation on a larger scale. These 3-inch-diameter, 1.5-inch-tall ISO-Puck 76 discs sit between your speaker’s feet and the floor, where they tame the transfer of vibrations between the cabinet and the floor or other surface it’s sitting on. Cupped tops let each cabinet’s foot nestle securely in place to prevent misalignment and tipped over gear. Each ISO-Puck 76 disc can handle up to 40 lbs. individually, and since they come in sets of two, it’s easy to get all the support you need.

Decoupling made simple

Decoupling is a remarkably simple concept. When your amp or speaker sits directly on a surface, it’s considered coupled with it. That coupled surface then effectively becomes part of the speaker, resonating at a lower frequency than average and creating false bass notes. In the studio, that means you’ll hear bass that isn’t really there, which will affect your ability to make good mixing decisions. Live, coupling your amps and PA speakers with hollow stages and hard floors creates booming bass that can overwhelm your venue or crank up the stage volume until the band can’t hear themselves play.

How do these things even work?

The IsoAcoustics ISO-Puck 76 is designed to sit between your speaker enclosure and whatever it’s sitting on. A sandwich of sophisticated polymers allows your speaker cabinet and the surface it’s sitting on to move independently, minimizing the amount of vibration that can pass from one to the other — whether that’s the elimination of false lows to pass from your speaker to the floor/stand or rumble in the floor from traveling up your mic stand and into your mic.

Isolation where you need it most

Everyone can look at an IsoAcoustics ISO-Puck 76 and know it’s meant to go under the feet of amps and speakers, but that’s not all they’re good for. Here at Sweetwater, we’ve gotten great results putting ISO-Puck 76 discs to use in less conventional ways. For instance, we’ve gotten great results by placing standard ISO-Pucks under regular mic stands, and ISO-Puck 76s are perfect under the feet of large studio booms. So look around and get creative. However you put your ISO-Puck 76s to work, we’re sure you’ll love them.
