Following on from the universal approval of our Heavy Duty Speaker Cables we are proud to introduce our Extra Heavy Duty Speaker Cables. These cables are specially designed to be the perfect interface between your Amp and Loudspeaker Cabinet, and to transfer the signal without losses or tonal change over the longer distances sometimes required when amps and cabs are in different areas (IE: Amp off-stage/ Cab on-stage).
The connectors used are Switchcraft Heavy Duty 1/4 inch jacks, which are all personally signed and sleeved by Pete Cornish after successfully completing our rigorous tests, The cable used is Ultra Pure Annealed Copper of very generous dimensions: each conductor has a total area of 2.5 Sq.mm. The insulator is a specially designed RNF Tough Rubber which maximizes the flexibility, heat and stress resistance to ensure long life after many years of professional use.
The cable jacket is constructed from an EMI Rubber which is exceptionally robust and is high pressure extruded over the insulated and twisted conductors. The "coil-ability" of these cables is excellent even at low temperatures.
We over-sleeve the cable with a woven gray Polyamide Braid that has excellent abrasion resistance and allows immediate identification of the XHD SPK Cables.
The tests carried out on every cable consist of :
1) Conductor resistance, Tip to Tip, must be less than 0.1 Ohms and we regularly achieve less that 0.05 Ohm in practice.
2) Conductor resistance, Sleeve to Sleeve, must be less than 0.1 Ohms and we regularly achieve less that 0.05 Ohm in practice.
3) Insulation resistance between conductors is measured at an applied voltage of 500VDC and must exceed 200 MegOhms.
