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. 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 four-nines (99.99%) oxygen-free copper deliver maximum conductivity to your loudspeakers and maximum purity in your sound. 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. 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.
