Designed to Keep Music Moving   A speaker cable has a straightforward job: transfer the signal from amplifier to loudspeaker as accurately as possible.   The challenge is doing that consistently across the entire audio range, without adding resistance, distortion or unwanted losses along the way.   That's exactly what Performance Speaker Cable is designed to do.   Low Resistance. Greater Control.   Performance Speaker Cable uses large 2.5 mm² conductors made from 99.999% oxygen-free copper to deliver exceptionally low resistance.   This allows your amplifier to maintain better control of your loudspeakers, helping preserve dynamics, detail and musical accuracy across the frequency range.   Consistent Performance Across the Audio Band   At higher frequencies, conventional speaker cables can suffer from skin and proximity effects that increase resistance and affect performance.   QED's proven X-Tube Plus™ Technology is designed to address this by promoting a more even current distribution throughout the conductor, helping maintain a more consistent electrical path from bass to treble.   The result is a cable engineered to perform consistently, regardless of what you're listening to.   Built to Last   A speaker cable only performs as well as the connections at either end.   That's why pre-terminated versions are fitted with QED Airloc™ plugs and spades. Using a proprietary cold-weld termination process, Airloc™ creates a high-conductivity connection that's protected against oxidation for long-term reliability.   It's the sort of detail that's easy to overlook. It's also the sort of detail that helps a system keep performing properly year after year.
