Sold singly, order 3 for most mid-sized components (place two at the rear corners and one front-center), or order 4 for heavier components. 

These UNI-CONE footers work with components from 10lbs all the way up to 400lbs. They work great with speakers, too. (I've added two photos showing the UNI-CONE's under smaller standmount speakers.)

The main body of the UNI-CONE has a clearance hole drilled, and you can tap this hole 8mm and use these with popular stands like the audio racks from Monoprice.

Use them for various projects, like creating your own audio platform using a hardwood shelf or butcher block.

They work great under amps, CD players, DACs, Streamers, and even turntables. In fact, the leveling screw feature is a greate way to isolate and level your turntable.

They come with a threaded spike and a threaded floor protector, the spikes sound best.Brand new. Ad is for one, order however many you need.
