Forty-three years since Kimber Kable launched its first speaker cable the 4PR, Russ Andrews has introduced entirely new versions of its woven geometry 4PR and bigger 8PR cables to the UK audio market.

The new 4PR and 8PR cables feature eight and 16 conductors per channel respectively, which now benefit from VariStrand conductors, comprised of purposely arranged different diameter copper strands within each conductor. These variable thickness wires claim an even response by not favouring any particular frequency.

Proven history

The woven design was developed by Ray Kimber back in 1979 when working in LA and noticing lighting rigs he was installing were generating RF noise, which was being picked up by speaker cables. After many hours of theorising and experimentation he managed to cancel this noise by weaving the cable.

Each of the woven conductors within 4PR and 8PR contain seven VariStrand wires, made from Kimber’s own high-purity oxygen free electrolytic copper, which claims a significant upgrade over the original models and has industry leading conductivity of 102% IACS, along with very low induction. 4PR’s positive and negative conductors are each 13AWG / 2.6mm2 and 8PR has 2 x 10AWG / 6mm2. Overall cable diameters are 9mm and 11.5mm respectively.

Clad in red and black finishes as a nod to the cable’s original colour scheme, example prices are £145 for a 2.5m pair of 4PR and £290 for 8PR in the same length, while a 4.5m pair of 4PR costs £221 or £442 for 8PR.
