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.
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.

Acclaimed by What HI-FI? Magazine; this 'Five Star' award winning pure copper loudspeaker cable boasts QED's advanced X-TubeTM technology and a massive 4mm2 cross sectional area. This results in a cable that delivers clear sonic advantages over conventional cable designs by maintaining a flat frequency response within the audio band.
Like its little brother, the medium sized 3020 bookshelf speakers benefits from the advanced, low distortion, wide dispersion, new 3000 Series Concentric Ring Dome tweeter; uprated crossover and improved low resonance cabinet. In addition, it boasts a larger 5 inch drive unit, with the new Aramid Fibre/Paper cone material. This larger driver delivers an extended big bass response with fast dynamics, wonderfully open, realistic midrange and an extraordinary 'being there' three dimensional sound.
