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 Combi Bases is an RDC cup with a Sorbothane pad insert (blue or red) and is designed to support either the RDC 2 or 5 cones, or the RDC Cone Cups. The RDC Combi-Base improves the dispersion of harmful resonance within your audio system and over a wider frequency range. When used as a loudspeaker support on suspended floors, the Combi-Base significantly reduces the transmission of bass frequencies to the room below. |
