SUPRA Quadrax Cables - Manufactured in Sweden -

Really affordable High-End Loudspeaker Cable featuring Tube Conductors of 4 x 2.0 mm2.

By spinning a multi-strand layer on an insulating core, Supra has increased the conductor cross-section - resulting in inductance of a vanishingly low 0.28 mH/meter. (Inductance robs your system of high frequencies.)

With high-grade polypropylene insulation and individually shielded conductors, Quadrax rejects noise as well as the most expensive speaker cables on the planet - at a fraction of their stratospheric prices. This is state-of-the-art performance - that the average guy can afford!

The tube conductor design means that 120 individually tin plated strands in a braid forms a tube around a PP plastic core. It forces the music signal to meet the same crossection area irrespective of frequency.

The CombiCon Connector

Quadrax comes with crimped M6 threaded adaptors and a set of connectors with corresponding threads. The picture shows the 24K Gold plated spade and banana/BFA connectors, The set includes all connectors for the absolute majority of todays connection options and most likely also your future preferences.

The transition between the cable and connectors is critical. In order to maintain the superior cable and contact properties, we crimp the unit together at high pressure, making a perfect, air tight, joint. Contact mounting is performed by trained professional using Supra contacts and tools.

If configured in a Star Quad conductor formation (single wire/full range) RFI pickup and outgoing magnetic fields (lowered inductance) are almost completely cancelled out, thanks to the symmetry of current in the opposite conductor pairs.

Finally the strand tin plating will counteract any current jumps tendencies between the strands.
