QED's multi-award winning XT400 speaker cable, utilising X-TubeTM technology
Silver-plated oxygen-free copper tubular conductor geometry. For use in the finest hi-fi and home theatre systems. This design delivers a massive cross-sectional area using X-TubeTM technology to eliminate the skin effect whilst maintaining a user friendly "figure of 8" geometry. This is QED's ultimate affordable upgrade for high end systems
X-Tube™ Technology
At low frequencies both X-TubeTM and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire conductor area. The result is that X-TubeTM delivers greater fidelity across the audio spectrum which would other wise be lost in ordinary cables.
Provides a low frequency path for the audio signal and delivers stunning high frequency detail
