About the QED Reference Subwoofer 40 Cable
Reference Subwoofer 40 is built mainly for low capacitance, which QED link to tight bass that keeps the rhythm of the music. Complementary Conductor Technology deals with small timing errors, and a floating Zn/Mn ferrite jacket absorbs high-frequency noise outside the audible band.
It is a coaxial design with a 99.999% oxygen-free copper braid for full screening, a foamed polyethylene dielectric and twin-leaf gold-plated Analoc2 RCA plugs with a low eddy current design.
It sits in QED’s Reference range. Use it from an amplifier, AV receiver, soundbar or active speakers to an active subwoofer.
