Quadrax 4x2.0 Loudspeaker cables

The Quadrax 4x2.0 sq. mm cable is based upon two specific Supra ideas:

1) The tin-plated OFC conductors themselves are based on the braided construction as used in the Ply Series, excepting that a central polypropylene dielectric is used to minimise inductance

2) The 4 conductors are arranged in a 2x2 grid, so that each conductor is "paired" with the conductor which is diagonally opposite, which reduces inline inductance and capacitance.

The resulting speaker cable is then terminated in a number of ways to suit customer needs.

We can offer factory-terminated Quadrax cables:

i) As standard, wired for bi-wiring, in "2 to 4" configuration (cables are "paired" at the amplifier end, but are terminated separately at the speaker end).

ii) We can also supply these cables for bi-amp use, with the cables configured in "4 to 4" mode, with each conductor being terminated separately at both ends.

iii) In "shotgun" configuration, (ie "2 to 2") with all of the conductors being "paired" at both ends. This effectively doubles the number of strands carrying the signal to the speaker and in some cases may be preferred to bi-wiring.

We mostly keep the bi-wired variant in stock in a range of lengths, with the other versions available "to order". Standard fittings are Supra CombiCon Crimp bodies, with either Banana/BFA tips or Spade connectors.

However, it is also available "off the reel" for those who wish to terminate the cable themselves.
