Where to buy Supra
Supra Sword speaker cable

Supra have developed many ideas for their cables over the past 25+ years since the company's' founding. And now one of the results of it's investment in Research and Development is the Supra Sword cable, designed by Johnny Svard (Svard is Swedish for Sword !!).

Sword is a speaker cable made from 24 conductors - 12 are wound one way (say clockwise) and the other 12 are wound counter-clockwise. When terminated (in the factory) great care is taken to ensure that all 24 conductors are in correct electrical and mechanical contact with the terminations.

This helps to ensure that the cable has absolutely no inductance. And as you may recall from your school days, with high level signals, inductance has one of the largest effects on the "sound" of speaker cables (and how they interact between the output stages of the amplifier and the passive components on the speaker cross-over network).

By reducing the speaker cable inductance to a negligible amount, Supra can claim to have a speaker cable that introduces no effects of it's own into the sound of the system. Thereby allowing the main components of the system to work harmoniously together.

Basic features:

Cross-sectional area = 3mm (12 AWG)
Number of wires (per cable) = 12+12
Insulation: PE
Jacket: Heat/Aging resistant PVC
External Cable Size: 9.3 x 18.4 mm
Cable Connection: Gas tight crimping
Resistance: 5.2 ohms / km
Inductance: 0.25 uH / m

Sword in supplied in a superb presentation case and can be supplied in many lengths, including 2m, 3m, 4m or 5m sets.

Please see our price list for currently available lengths.

Each set is terminated with Supra CombiCon interchangeable connectors (choice of BFA, Banana or Spade connectors are supplied in each box). Alternatively, we can optionally supply Sword with FIXED spade connectors.

Please also note: Sword is a "single-wire" cable - that is, if you want to bi-wire, you'll need 2 sets.

Sword Jumpers
Sword can also be supplied as a pair of 28 cm "jumpers" to connect across bi-wire terminals (and which replace the inferior sounding gold-plated brass "jumpers" fitted to many bi-wireable speakers when used in single-wire mode).

Sword interconnects
A matching interconnect cable, terminated with either lockable phono (Sword-ISL) or XLR connectors (Sword-IXLR) is also now available.
