QED Subwoofer 40 has been designed primarily for low capacitance, as this has been identified by QED as a major factor making for a tight sound which retains the rhythm of the original piece - vital when it comes to the 'bottom end!" Minute timing errors are ameliorated by the use of QED's Complementary Conductor TechnologyTM combined with a special floating Zn/Mn ferrite jacket to absorb very high frequency noise signals outside the audible band. The QED AnalocTM plug design helps to control eddy currents which can also affect the micro-timing of the audio signal, maintaining high- fidelity from start to finish.
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.
