Pyramid Cones

The Pyramid Cones are the basic building blocks of the "BDR" system.  They are, in most cases, the initial interface in a vibration control system, and should be the first pieces utilized in developing your setup. Overall results have almost always been best when an entire system has been fitted with the Pyramid Cones, rather then concentrating on a single component.  The Pyramid Cones have proven an effective means of vibration control under all types of components:   speakers, turntables, transports, CD players, preamps, DAC's, amps, crossovers, video gear, even medical and computer equipment.  With a crush point of 10,000 pounds "each" , the Pyramid Cones can be used virtually anywhere.  The best results will be obtained when the Cones are placed under or near the critical elements of the component:  drive mechanisms, power supplies, transformers, tonearm mounts, motors, etc.  The proper placement will significantly effect the performance of the Cones.  The rule of thumb is the tip of the Cone should be toward the resonant surface.  For example, under a CD transport sitting on an MDF shelf, the tips of the Cones should be pointing down.  A general guideline is to start with the Mk. 3 Cones under solid state and digital equipment, and the Mk. 4 Cones under tubes.  (Please note: this is only a suggested starting point, as we have a number of cases where people prefer the opposite Cones under the exact same component.)  Room acoustics, rack structure, personal taste and other considerations all come into play.)  In addition, the two different types of Cones may be mixed together for "in-between" results if desired.
