X-tube technology – as used in the award-winning XT40
Conventional cables can fail to conduct high frequencies uniformly across the entire conductor area. QED's X-Tube cable technology allows a near-linear signal transfer at treble frequencies for greater detail and realism of sound - especially at higher frequencies.
Pure copper for a detailed sound
Using 99.999% oxygen-free copper cable, there's very low resistance, which makes it easier for your amplifier to drive your speaker as well as delivering a purer sound. It also makes the cable suitable for longer cable runs, with far less quality loss over longer lengths.
Connect up with QED’s Airlock plugs and enjoy one of the best-sounding speaker cables in its class.
Low-Loss Dielectric
Music signals in a loudspeaker cable move back and forth many times every second. The insulating material used to separate the send and return conductors from each other (the dielectric) has to be charged and discharged every time. Not all of the energy stored in the dielectric during each charge cycle is completely returned during each discharge cycle which has a detrimental effect on the fidelity of the sound you hear. That’s why at QED we use low-loss dielectric materials such as Polyethylene (PE) or Teflon™ (PTFE) in preference to cheaper PVC alternatives found in inferior unbranded cables.
