Measuring just 0.34 tall and slightly less than 2 round, the Black Diamond Racing LM Disc is surprisingly effective. It improves bass weight and control, extends and smooths treble response, and greatly enhances midrange clarity and presence.
Just slip a set under the stock feet of any piece of gear to hear an instant difference. We recommend using them under the BDR Cones for an incredible upgrade. The LM Discs can be used under speaker spikes or under any equipment rack, as each LM Disc can handle over 400 pounds.
