The QED speaker cable story began in 1973, with the launch of the world’s first specialist speaker cables, QED 42 and 79 strand, now household names in the audio industry. 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”, a 40 page White Paper 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.
The mega-high-performance SuperCenter XXL is only 35” wide and includes four 5-1/4" drivers, the GoldenEar High Velocity Folded Ribbon tweeter, three planar passive radiators, and our unique linear-phase crossover, employing fully balanced technology and precision film capacitors.
QX16/2 LSZH are high performance and exceptional quality installation speaker cables with the added bonus of a fully certificated LSZH fire rated design. They deliver excellent levels of performance in all multi-room and home cinema installations.
QED Supremus loudspeaker cable is the ultimate expression of sound born of pure science. Developed without compromise, it has been 21 years in the making. The largest cross sectional area of pure copper ever incorporated into a QED loudspeaker cable, enables Supremus to deliver the ultra-low resistance required to ensure perfect fidelity of the musical signal.
