Reference Sensible Speaker WiresDesigned to deliver full bandwidth and maximum conductivity without coloration or compromise, ELAC Reference Sensible Speaker Cables are one of the most cost-effective improvements you can make to your system! Multi-gaugeIndividually insulated conductors for maximum flexibility. There’s nothing worse than heavy gauge cables that won’t bend, stay put or lie flat. Reference Sensible Speaker Cables utilize multiple-gauge individually insulated conductors to maximize flexibility without compromising performance. Oxygen free12 AWG 99.99% oxygen free copper conductors for superior sound quality. Deliver maximum conductivity to your loudspeakers and maximum purity in your sound. Gold Plated beryllium copperHigh-conductivity beryllium copper contacts for maximum signal transfer.The 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. Precision-formulated PolyethyleneIt 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.
