QED Reference 40 subwoofers

Reference Subwoofer 40

the new standard for timing, precision and rhythm.

The QED Subwoofer 40 has been designed primarily for low capacitance, as this has been identified by QED as an important factor contributing to a crisp sound that keeps the rhythm of the original track – fundamental when it comes to the "bottom end!" Minute timing errors are improved by QED's Complementary Conductor Technology™ combined with a special Zn/Mn ferrite floating jacket to absorb very high-frequency noise signals outside the audible band. The QED Analoc2™ plug design helps to control eddy currents that can also affect the micro-timing of the audio signal, maintaining high fidelity from start to finish.
