QED's multi-award-winning XT400 speaker cable features silver-plated oxygen-free copper conductors arranged in a tubular geometry using X-Tube™ technology. Designed for use in top-tier hi-fi and home theatre systems, the XT400 delivers superior audio performance by eliminating the skin effect and providing a massive cross-sectional area in a convenient "figure of 8" format. At low frequencies, both X-Tube™ and standard cables perform similarly, but at higher frequencies, X-Tube™ maintains consistent signal transfer across the conductor, whereas standard cables fail to conduct uniformly. This leads to reduced distortion and enhanced high-frequency detail. Additionally, the polycore design of X-Tube™ significantly reduces loop inductance, improving clarity and fidelity without the cost and complexity of more advanced cables. |
