Iso-Pucks are round acoustic isolator pads made from a flexible but sturdy, hard rubber material. A little smaller than a hockey puck, they measure 1.18 inches (28mm) tall by 2.4 inches (60mm) in diameter. They are useful anywhere isolation is required to decouple vibrational sources from shelves, floors or furniture. You can use them under: speakers, turntables, subwoofers, instrument amplifiers or DJ rigs.
Decoupling vibrating loudspeaker cabinets from the floor will prevent sympathetic vibrations, buzzes and creaks when certain frequencies (notes) are played.
Their round shape makes them flexible enough to be positioned easily in the narrow spaces atop a recording studio’s console meter bridge or on a home studio monitor speaker shelf. A single Iso-Puck is rated at a maximum load of 20lbs (9kg) and three or more can be combined to support the heaviest of monitors or equipment racks.
Like IsoAcoustics’ Aperta 200 Speaker Stands, the Iso-Pucks use a flange suction cup on their top surface that adheres to the bottom of the monitor’s cabinet to resist lateral side-to-side movement.
I’ve deployed four Iso-Pucks under my subwoofer that’s placed on a hardwood floor. The sub weighs 27.3 pounds and, before isolation, certain low frequency bass notes caused a couple of the planks in the floor to vibrate and buzz. Now with the sub resting on only the four Iso-Pucks, the buzzing is totally gone plus the subwoofer seems to stick to the floor and doesn’t easily slide around anymore.
IsoAcoustics’ Iso-Pucks come in 2-Packs that sell for $59 MSRP.
