14 AWG 99.99% oxygen-free copper conductors for superior sound quality. Oxygen. It’s the third most abundant element in the universe. That’s OK for the universe, but not for your speaker cables. That’s why our engineers specified four-nines (99.99%) oxygen-free copper to deliver maximum conductivity to your loudspeakers and maximum purity in your sound. Premium, high-temperature, nylon-braided PVC jacket for easy handling. There’s nothing worse than cables that won’t bend, stay put or lie flat. Sensible Speaker Cables have a durable braided jacket that withstands high-traffic environments and repeated handling. The sophisticated pattern makes these speaker cables a welcome addition to the best-looking systems. Precision-formulated polyethylene dielectric for minimal signal interference. It isn’t just wire metallurgy that affects your sound what covers the wire matters too. ELAC’s polyethylene dielectric not only provides superior insulation, but it has a low dielectric constant as well as offering low dielectric loss. So your speakers receive the purest, cleanest-sounding signal imaginable. Machined, high-conductivity beryllium copper contacts for maximum signal transfer. While most affordable cables use inferior plated zinc connectors, ELAC insists on brass. Then those connectors are fitted with 24K gold-plated beryllium copper contacts for maximum conductivity and reliability of contact, while threaded anodized barrels won’t come unscrewed during use.
