QED Reference Subwoofer 40

Reference Subwoofer 40, the new standard for timing, accuracy and rhyth 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 improved by 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 Analoc2™ 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.
