Supra Quadrax 4×2 mm² – High-End Bi-Wire Loudspeaker Cable for Superior Sound Clarity

Unleash the full potential of your audio system with the Supra Quadrax 4×2 mm² Bi-Wire Loudspeaker Cable. Engineered with precision and crafted for audiophiles, this premium Star Quad (2>4) bi-wire cable combines Supra’s advanced Tube Conductor Technology with robust CombiCon crimp connectors to deliver an unparalleled listening experience. At an extraordinary value, it redefines what’s possible in high-end audio performance.

Innovative Design for Flawless Sound Transmission

Quadrax’s unique tube conductor design ensures that each of the 120 individually tin-plated strands forms a tubular braid around a durable PP plastic core, creating a conductor that accommodates frequencies with incredible precision. This sophisticated design allows high frequencies to travel along the outer edges while lower frequencies remain stable, resulting in an even cross-sectional area for all signals. With the Star Quad configuration, RFI pickup and magnetic interference are nearly eliminated, preserving pure sound clarity and exceptional frequency response.

Uncompromised Audio Quality for Enthusiasts

Ideal for high-power amplifiers and quality speaker systems, this bi-wire version of the Quadrax is perfect for those seeking to experience music with heightened dynamic range, vivid transparency, and fast transients. Users consistently describe it as “explosively dynamic” and “straightforward” in sound—true to Supra’s reputation for no-nonsense, precision-engineered cables that allow you to hear every note exactly as intended.

Built to Last with Optimal Performance

The Quadrax is crafted with a high-grade Polypropylene (PP) insulation that is both chemically and physically stable, offering exceptionally low capacitance to prevent unwanted phase shifts or treble roll-off. Every cable is pre-terminated with Supra’s expertly crimped CombiCon connectors, forming a secure, air-tight seal for optimized signal transfer and durability, giving you a seamless, long-lasting connection.

Versatile and Future-Ready Connection Options with CombiCon M6 Connectors

This cable is equipped with CombiCon Crimp M6 connectors, which feature an M6 threaded adaptor for quick and easy switching between spade and banana connectors. The set includes both options to accommodate today’s most common connections, providing a future-ready solution that adapts as your setup evolves.

Upgrade to Supra Quadrax 4×2 mm² for an elevated audio experience. Designed to captivate audiophiles, this cable combines dynamic sound and precision engineering to deliver music the way it was meant to be heard—authentic, clear, and powerfully engaging.

Supra Quadrax Bi-wire cables

I recently had to move my components away from between the speakers which meant I needed a 9m set of speaker cables. I had read good things about Supra cables so decided to give them a go.
I rang Mark ( yes, that's right, I was actually able to speak to the person who was going to make my cables! ) and we had a brief discussion about the Rondo cables and I emailed him later for a quote. After seeing my system, Mark suggested that the Quadrax cables would probably be more appropriate and offered me a very good price so I took the plunge.
As part of the service Mark burned in my cables which took 4 days. They duly arrived about a week after I ordered them and I have to say that first impressions were very favourable. Each set came in its own bag and were beautifully made. These are substantial cables! I plugged them in between my Williamson KT66 amps and the Tannoy 15" Monitor Golds and away I went.
I haven't had them long but initial listening suggests an improvement in imaging and detail which is saying something because the Tannoys were no slouches in that department before! Needless to say I am very happy with my purchase.
All through the process, Mark and his wife Charmayne have communicated very well and have been a pleasure to deal with. I couldn't recommend them more highly.
