The ISO-PUCK 76 is the latest addition to award winning ISO-PUCK isolator series. With a weight capacity of 40 lbs (18 KG) per unit, the ISO-PUCK 76 is designed for heavier studio monitors, speakers and subwoofers. Three or more pucks can be used at a time depending on the weight of the speaker or monitor. The unique patented design of the ISO-Puck provides a high degree of isolation while resisting lateral movement and oscillations, which results in greater sound clarity and focus. This versatile isolation tool is possibly the most cost effective upgrade available for improving the performance and clarity of your speakers or monitors. The ISO-PUCK upper flange "suction cup" design adheres to the underside of the cabinet making the upper isolator live with the speaker, while the lower isolator anchors to the supporting surface. All the energy is managed within the core of the ISO-PUCK isolators which are carefully tuned to provide superior isolation and control while remaining on-axis. The small, compact design makes the ISO-PUCK series the ideal speaker isolation solution to carry with you from studio to studio, session to session or anywhere you want to improve the sound clarity and provide consistent results from one location to the next for your studio monitors or speakers.
