Track Audio's Solid Feet (formerly Coupled Isolation Feet) are big, heavy solid, steel spikes. They have a >150Lb rating each. A set of four holds over 630 lbs. They make a huge difference under speakers, racks, amp-stands, etc. They come standard with a set of Track's stainless cone cups. Solid Feet are the most massive adjustable after-market spikes we've ever seen. Weighing in at just under a pound each, these are not just big, they're cleverly engineered as well. Solid Feet are a stunning upgrade for any component.

Providing superior isolation and the ability to hold considerable weight, Track Audio Isolation Cups are machined from stainless steel with a Delrin insert spike cup to prevent vibrations traveling in either direction. They are finished off with soft industrial felt underneath. Isolation Cups protect your floors, isolate your gear, and let your music come alive like never before. They're most effective when used with Isolation Feet, but may also be appropriate for use with Spikes when used on a very hard surface such as concrete or marble flooring.

Track Audio Small and Large Solid Cups provide excellent coupling by siphoning away large scale vibration and channeling it to the supporting surface. The broad surface area and large amounts of stainless steel offer enormous weight handling capability. They are ideal for use under racks, subwoofers, and speakers. Large Solid Cups accommodate up to 150 pounds. Small Solid Cups provide much of the same coupling effect of their larger siblings, but in a more compact size that is less visually obtrusive and mates better with Track Audio Spikes.
