But not every speaker has removable screw-in feet. That's where the ISO-PUCKs shine. Install these tiny feet under your studio monitors, guitar amp, bookshelf speakers — any piece of gear you use to produce (or reproduce) music. Easy does it There's a lot of advanced science that goes into the construction and performance of the ISO-PUCKs. Their unique design gives you better sound by reducing vibrations and other acoustic distortions. But my favorite feature is how simple they are to use. Just place them under your speaker, and you're ready to rock. No tools required. Portable for great sound anywhere Use the ISO-PUCKs in your home studio or listening space. They're also ideal for musicians or DJs who frequently set up and break down their gear for live shows. They provide you with consistent performance, so you can take "your sound" with you on the road.
