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 Clearlight Audio RDC 3 cones are large diameter cone measuring 50mm in diameter, but only 23mm tall, load capacity 25kg per cone. The larger flat surface area of the RDC 3 cone provides a better, more stable support for electronic components. Its composition and shape offer improved dissipation of vibrations of a lower modulation, which can adversely affect the performance of electronic circuitry.
