Get More Precise Imaging, Better Dynamics, and Improved Inner Detail from Your Music: IsoAcoustics Iso-Pucks Improve the Sound of Any Loudspeaker and Dissipate Unwanted Energy Made specifically to counteract the movements created by speakers, IsoAcoustics Iso-Pucks are designed to be placed right under the cabinet and help resist the lateral motions caused by the movement of the drivers.

Iso-Pucks yield outstanding improvements when coupled with tower and monitor speakers – as well as subwoofers. They even lend immediately audible improvements when put under turntables and CD players. You'll hear clearer, more dynamic sound, improved inner detail, and more precise imaging.

Featuring multi-part construction that dissipates vibrational energy and decouples your speakers from support surfaces, Iso-Pucks can be used in multiples to accommodate different (and heavier) masses.

Their suction-cup-like form factor means they securely attach to speakers and components, while their round shape makes placement a breeze. Each Iso-Puck supports up to 20 pounds. Sold in pairs and 100% Music Direct Guaranteed. "A side-by-side speaker test with and without Isoacoustics is a revelation.

These pucks are a relatively inexpensive and a versatile way to add the technology to your setup." – Gear Patrol, The 8 Best Vinyl Accessories
