QED XT40i Speaker Cable Packed – 2x2m

As befits a company rapidly closing on its fifth decades at the forefront of speaker cable design, QED’s brand new XR40i speaker cable build the formadable reputation of the XR40 cable it replaces and offers a decisive step up in sound quality.




By Increasing the separation of the conductors inside the cable, and therefore the amount of ait between them, QED has created a low-loss Air Gap Dielectric. This technologu halves the dissipation and capacitance charatecristics of the cable, and result in numerous improvements – particulary where timing and thythmic accuracy are concerned

Forming the cable conductors into a tube-like shape around a hollow insulating rod in the centre of the cable equalises current densities, delivers very low indutance and presents a consistent, event load to an amplifier. The result is a cable that retains more of the finest musical detail, that handles rhytms and tempos in the most and musically satisfying way and the outpeform rival design costing far more.
