General presentation QED Reference Subwoofer 40 cable

The QED Subwoofer 40 has been designed for low capacitance, as this has been identified by QED as a major factor for a tight sound that keeps the rhythm of the original track - vital when it comes to the "bottom end!" Timing errors are improved by using QED's Complementary Conductor TechnologyTM combined with a special Zn/Mn ferrite cladding to absorb very high frequency noise signals outside the audible band. QED AnalocTM connectors help control eddy currents that they can also affect the micro-sync of the audio signal, maintaining high fidelity from start to finish.
