Hyper Achromatic Z Bi-wire

The bi-wire variation of our Hyper cable family. Bi-wire cables can offer performance benefits when the two halves of the loudspeaker's crossover are electrically ‘separated’ to allow bi-wiring) (and bi-amping, if so desired). Available in 2–4 and 4–4 connector configurations.

A sophisticated bi-wire cable engineered to offer a high level of transparency and wide dynamic range.

The cable employs conductors comprising 72 0.25mm² high-purity OFC (Oxygen Free Copper) strands encapsulated within a carefully selected high-efficiency PTFE (Teflon™) dielectric coating. The resultant conductor is embedded within an anti-vibration filler and finished in the Hyper gloss black sleeve.

Our latest-generation Achromatic Z-plug is a proprietary low-mass, self-cleaning, precision-crimped (cold-weld) speaker connector fitted as standard. These cables are also available terminated with our cold-weld high quality OFC spades or our Transpose Modular Termination System. Transpose options include Z-plugs, expanding 4mm plugs or OFC spades in gold or silver.
