The Black Diamond Racing Pyramid Cones Mk3 and Mk4 are the initial interface in a vibration control system. With a crush point of over 4,500 kg, the Pyramid Cones can be used virtually anywhere. The proper placement will significantly effect the performance of the cones so the rule of thumb is the tip of the cone towards the resonant surface. For example, under a CD transport sitting on an MDF shelf, the tips of the cones should be pointing down.
How they work:
The Cones work like other brands/types of cones and spikes due to the shape, i.e. the vibrations are rejected due to the small contact area on the point. BUT, and here is where they are in a class of their own, they also absorb and convert mechanical vibrations into heat. They are extremely effective at doing this and work over a very wide frequency range.
The other BDR components work in the same way and the level of isolation increases as you fit them together with the Pyramid Cones.
They are so effective that they are equivalent to placing your item on 10 inches of granite + 2 inches of MDF !!!! They have very high damping and a very low Q.
They really do work!!!!
