QED Reference Subwoofer 40 Cable – 6.0m

The QED Reference Subwoofer 40 sets a new benchmark in timing, accuracy, and rhythm, making it ideal for high-fidelity subwoofer connections. Designed primarily to minimize capacitance, this cable ensures tight, rhythmically accurate bass performance—a crucial feature for audio systems focused on the low end. It incorporates QED’s Complementary Conductor Technology™, which uses two conductors of differing diameters to deliver enhanced micro-timing and detail. Additionally, a floating Zn/Mn ferrite jacket helps suppress high-frequency noise beyond the audible range, while the updated Analoc2™ RCA plug design minimizes eddy currents and maintains signal integrity throughout. The Reference Subwoofer 40 is part of QED’s award-winning lineup, offering a premium construction that includes silver-plated oxygen-free copper, high-purity connectors, and full electromagnetic shielding. With a reduced diameter compared to other reference models, it is also more flexible and easier to route during setup.
