QED Reference Subwoofer

QED Subwoofer 40 has been designed primarily for low capacitance, as this has been identified by QED as a major factor contributing to a tight sound that retains the rhythm of the original piece, which is vital for the bottom end. Minute timing errors are improved through 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 control eddy currents that can also affect the micro-timing of the audio signal, maintaining high fidelity from start to finish.
