QED Performance XT25 Pre-Terminated Speaker Cable
This 2.5 meter pair of XT25 Cable is terminated with QED Airloc Banana Plugs.
The QED speaker cable story began in 1973, with the launch of the world's first specialist speaker cables, QED 42 and 79 strand. Building on this longstanding British speaker cable heritage, QED embarked on an exhaustive research program into cable parameters which began in 1995 and continues into 2017 with the release of "The Sound of Science", distilling the research published since 1973 by QED.
These reports set out the "top down" design-principles that have resulted most recently in the development of QED XT25 loudspeaker cable - the new class leading standard in budget to mid-range speaker cables.
QED has won more What Hi-fi? Awards than any other single brand and with XT25 this heritage is delivered at a sensible price. Unlike most other manufacturers. 2. X-Tube™ Technology....but with a twist
In loudspeaker cables high pitched sounds are forced to travel towards the outside of the conductor and so are able to use less and less of the available cross-sectional area as the pitch increases. This is called the “Skin Effect”. The XT25 variation of QED X-Tu Insulation LDPE jacket with 100% coverage of Aluminium Mylar tape wrap Plugs and spades QED Airloc Forte banana plugs Technology solves these problems by creating a hollow tubular conductor geometry out of individual conductor bunches through which each frequency can pass with equal ease when compared to traditional solid or stranded conductors.
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.
Speaker cables need to have a large current carrying capacity. If the electrical resistance of the cable is too large, part of the music signal will be lost, causing a detrimental effect on the sound you hear. To stop this from happening we make the resistance of our speaker cables as small as possible. We do this by using the largest practical area of copper within the size constraints of each cable. In order to squeeze the last drop of performance from the conductors we make sure that there are no impurities in the copper which would defeat the object of making them so large. That’s why we use 99.999% oxygen-free copper exclusively.
Unique proprietary technology and trademarked geometries plus our award winning heritage all combine to create audible sonic improvements when compared to other loudspeaker cables.
Come in for a listen, we will be happy to let you hear the difference.
