QED Silver Anniversary XT Bi-Wire Speaker Cable – 50m

The Silver Anniversary XT Bi-Wire cable has been designed to be the natural successor to the multi-award-winning Silver Anniversary speaker cable. This enhanced version combines the proven performance of its predecessor with X-Tube™ technology to minimize skin effect and ensure consistent signal transmission across all frequencies. At low frequencies, both X-Tube™ and conventional cables behave similarly, but as frequencies increase, X-Tube™ maintains near-linear signal transfer, while conventional cables suffer from uneven conduction. This results in more detail and fidelity in your audio playback. In traditional cables, higher frequency currents are concentrated at the periphery of the conductor, reducing the effective cross-sectional area and causing distortion. X-Tube™ counters this with a polycore design that minimizes inductance and maintains performance, producing clearer high-frequency detail and reduced signal loss.
