QED Reference Subwoofer 40 Cable

QED's Reference series is the penultimate range of interconnects in their extensive catalogue. Featuring an entirely new design concept, the cordage of the Reference models are designed first and foremost for low capacitance. This is because QED has identified this factor as being a significant player in the high fidelity listening experience, by retaining a low capacitance, sound signals are better looked after and allow for a more collected and detailed hifi performance.  The Reference range also utilises QED's 'Complementary Conductor Technology' to ensure a high-frequency detail, and their Analogue Technology to optimise signal integrity. All QED interconnects and cables feature a lifetime warranty, including the Reference series.

QED Reference Subwoofer is the interconnecting cable that has been designed specifically for use within your A/V set-up, allowing you to bridge the connection between the amplifier and active subwoofer.

With outstanding quality in mind, QED has brought the Reference to us with 99.999% Oxygen Free Copper conductors, 8 leaf 24K gold connectors, foamed LDPE insulation for significantly reduced dissipation and precision-engineered plugs on either end, featuring integrated user grips.

An in interconnect with quality, yet affordability in mind, QED Reference Subwoofer is a perfect addition to your A/V set-up for a dramatically increased performance from your active subwoofer component.
