STANDARD Carbon/Silver Resistors
(For Loudspeaker Cross-Overs) Non-inductive, pure silver lead-out, phenolic tube, pure graphite resistive element.
Length 65 to 135 mm / Diameter 8mm D
Resistor 0.5R-1R2 are 5 watts / 1R5-30R are 10 watts / 47R-50R are 5 watts
pcX is initally stocking a limited range of values....however, we can source any value from 0.47 ohm up to 300 ohms (non-stocked values have a 3 to 4 week lead time).
Designed by DUELUND Coherent Audio of Denmark for Loudspeaker Cross-Overs these 5 to 10 watt non-inductive (they are purely resistive, since they are a solid element and have no electrical characteristics of a coil) resistors utilizing graphite as the resistive element, and pure silver wire for the lead out material. A phenolic cylinder is used to protect the resitive element itself.
The special charcteristic about this resistor is that it displays a negative temperature coefficient. For example, when the voice coil of a speaker heats up, it's impedance rises. The DUELUND Graphite Resistor counteracts this by means of a decreasing impedance. The results are greatly improved dynamics from the driver.
Duelund VSF Caps and Graphite Resistors are used by a growing number of high-end speaker manufacturers...such as Gryphon Audio Design and Peak Consult. Peak Consult was awarded Joint Loudspeaker of the Year 2006 in Stereophile magazine.
