# QED Reference Subwoofer 40 Cable

The QED Reference Subwoofer 40 is a high-performance RCA cable designed to deliver deep, controlled bass between your AV receiver or amplifier and your subwoofer.

Engineered with a focus on extremely low capacitance, it helps preserve the timing and rhythm of low-frequency signals, ensuring tight, accurate bass performance in both music and home cinema systems.

Using QED’s Complementary Conductor Technology™ with silver-plated oxygen-free copper conductors, the cable is designed to minimise timing errors and maintain signal accuracy.

A floating Zn/Mn ferrite jacket absorbs unwanted high-frequency noise, while precision Analoc2™ connectors help reduce eddy currents and maintain clean signal transmission from source to subwoofer.
