IsoAcoustics ISO-PUCK 76 Isolation Feet - Pair

The Heavy ISO-PUCK for Big Monitors, Subwoofers and Amp Cabinets

The IsoAcoustics ISO-PUCK 76 is sold in a box of two. Each puck carries up to 40 pounds. IsoAcoustics calls for at least three under every speaker, so one large monitor or subwoofer needs two boxes. Three pucks carry 120 pounds and four carry 160.

A big cabinet puts real energy into whatever it stands on. The floor or console takes it, then hands it straight back into the box. IsoAcoustics designs the ISO-PUCK 76 to manage that energy inside the puck. The cabinet rides on the isolator instead of the surface.

Fit, Load and Materials

Each ISO-PUCK 76 carries up to 40 pounds. Three handle 120 pounds and four handle 160. IsoAcoustics says to stay 10 percent under those limits to allow for uneven weight. No minimum is published, but a puck loaded far under its rating never reaches its working range. A 40-pound monitor belongs on the standard ISO-PUCK.

The 76 in the name is its width in millimeters. Each puck is 3 inches across and 1.5 inches tall, so it raises a cabinet about an inch and a half. IsoAcoustics describes an upper flange that adheres to the underside of the cabinet and a lower isolator that anchors to the surface below.

All the energy is managed in the core of the puck, and nothing is bolted to the speaker. The puck is made for floor stands, consoles, soffits, stages and hard floors. Set each one with the logo facing forward, in line with the drivers. The IsoAcoustics online weight selector confirms the count.

Who Is the ISO-PUCK 76 Best For?

• You run large monitors of 60 to 120 pounds each — three pucks per cabinet carry them inside their working range
• You want a subwoofer off the floor without a stand — an inch and a half of lift decouples it, and four pucks carry up to 160 pounds
• You gig with a bass or guitar cabinet — IsoAcoustics rates the puck for amps on a stage or hard floor, and the pucks pack flat
• Your speakers sit in soffits or on a console bridge — nothing is screwed in, so the pucks lift out when the room changes
• Your speakers weigh less than about 40 pounds each — the standard ISO-PUCK, rated 20 pounds a puck, keeps a lighter monitor inside its working range

How Do You Set Them Up?

Set three pucks under each cabinet, two in front and one centered at the back, or four at the corners for a wide or deep box. Face the logo forward. Lower the cabinet onto them and press so the flanges seat. Level a subwoofer afterward if the floor is uneven.

Pairs Well With

What most ISO-PUCK 76 owners shop next.

• Speaker stands — get the tweeters to ear height before you isolate
• Floor and carpet protection discs — a firm footing on carpet or a soft floor
• Speaker cables — the next link in the chain after the speakers are settled
• Speakers — the bookshelf and desktop models these are made to sit under

Frequently Asked Questions

How many do I need?

IsoAcoustics requires at least three pucks under each speaker or subwoofer, and four for a wide cabinet. Each box holds two. One cabinet needs two boxes and a stereo pair needs at least three.

Which ISO-PUCK model fits my speakers?

Choose by weight per cabinet: mini 6 pounds a puck, ISO-PUCK 20, ISO-PUCK 76 40. Stay 10 percent under the limit, and use the IsoAcoustics online weight selector if a cabinet sits near a line.

Will it work under a subwoofer?

Yes. IsoAcoustics lists subwoofers among the uses for the ISO-PUCK series. Use three or four pucks with the logo facing forward. Keep the total weight under the combined rating.

How much height does it add?

Each puck is 1.5 inches tall and 3 inches across. The cabinet sits on the pucks rather than on its own feet, so it rises about an inch and a half. Check the clearance to any shelf above.
