The QED Subwoofer 40 has been designed primarily for low capacitance. QED’s exhaustive R&D has identified this as a major factor making for a tight bass response retaining the rhythm of original recordings. And minute timing errors are ameliorated by the use of QED’s Complementary Conductor Technology™ combined with a special floating Zn/Mn ferrite jacket to absorb very high frequency noise signals outside the audible band. The QED Analoc™ 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.
Complementary Conductor Technology
Unlike conventional analogue interconnects, the Reference Audio 40 uses two silver plated 99.999% Oxygen Free Copper conductors of different diameters to carry the same audio signal. This has the effect of providing an alternative signal path for more subtle audio components which might otherwise become time smeared in a single audio pathway. The Reference Sub Woofer 40 is further optimised by having a 25% smaller diameter than Reference Audio 40 making it more convenient for those long runs around the room!
Analoc™ RCA Plugs
An all new locking design features small high purity gold plated copper conductors in place of the usual large volume brass body found in ordinary “high quality” plugs. This cuts down or eliminates the tendency for the changing magnetic field in the conductor to induce eddy currents which are thought to affect the micro-timing of the audio signal. Coupled with its hollow central pin, which is designed to combat the skin effect in the same way as QED’s X-Tube speaker cables, the new QED Analoc™ plug fully maintains the fidelity of the audio signal.
