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.
A smaller cone measuring 30mm in diameter and only 10mm tall. The Clearlight Audio RDC 5 cone is ideal where a more discrete means of isolation is preferred and can be used under electronic components, on the top of loudspeaker stands to isolate the loudspeaker cabinet. The RDC5 is ideal for use with the RDC Cone Cups and Combi-Bases, to further enhance the dissipation of unwanted resonance or vibration.
