Clearlight Audio - Isolation - RDC 4 Cones

RDC stands for Resonance Dampening Compound. We know that acoustic waves, resonance, spreads within a homogeneous material at a constant speed and direction. If we introduce another material, speed and direction are effected, resonance is influenced and cannot pass without being affected by the physical change in material. Therefore inhomogeneous materials do not conduct resonance well.

RDC has been created from micro-granules of materials at each end of the elasticity module with the same mass. The result is a very high mechanically stable inhomogeneous material that offers equal treatment of resonance frequencies across the audible range. Resonance is dampened equally.

RDC cones are now more than ever in demand as contemporary, apartment style, living, hard floors, and glass furniture/shelves in particular create a greater need for damping of resonance. Loud speakers, speaker stands, hi-fi components and now combination gaming/hd/blu-ray machines alike, can all benefit, not to mention taming the sub woofer!(There are 100’s of uses – even non hi-fi) Please see below to see where and how RDC cones can be used. RDC will last a lifetime and is, as has been quoted many times, the only accessory upgrade that enhances your system without taking anything away. In fact if anything it will expose areas of the system to be improved upon which may have been masked previously.

The RDC 4 cone is a two-part cone measuring 55mm in diameter and 25mm tall, load capacity 35kg per cone. The Clearlight Audio RDC4 cone has a flat base section which incorporates 8 Sorbothane pads and a domed top section which rests on these pads. The effect of this construction is to further isolate electronic components from whatever support or shelf system you may use and this in turn affords your system a more neutral environment in which to perform. Ideal as a platform support bearing high end turntables.
