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.
