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.
