Bipolar cable for connecting acoustic loudspeakers in tinned copper OFC. Unshielded version
The cable is supplied in a single piece of the quantity purchased in multiples of 1m.
The standard Ply 3.4 cable offers some interesting features; the geometry is designed to minimise inductance, which helps improve transient response. The designer has tried to optimise many of the parameters that are considered fundamental for good audio reproduction.
The conductors consist of 192 individually tinned (with pure tin) OFC copper threads in such a way as to minimise the skin effect by acting as a semi-Litz-type cable.
Furthermore, this tinning process (not silver plating!) helps to limit conductor jumps, thus transforming the multi-strand cable into a kind of solidcore (single conductor).
Supra claims that the advantage of pure tin over silver lies in the fact that copper and tin ‘mix’ together rather than creating a kind of diodic ‘barrier’ like that between copper and silver. Furthermore, pure tin protects OFC copper from oxidation.
Finally, the rectangular cross-section allows easier interfacing with most speaker (or banana) connectors.
The technical specifications of Ply 3.4 (3.4 is the mm2 cross-sectional area) claim a resistance of 5.1 Ohms per km (kilometre!) and an inductance of 0.2 µH per metre.
Square profile cable of 7mm per side.
The SUPRA PLY 3.4 (loudspeaker cable) was named 'OUTSTANDING PRODUCT' by the British hi-finews magazine. SUPRA Ply 3.4: No NonSense
