Subwoofer cable QED - Reference Subwoofer 40, 2x RCA, 3 m, black

The QED Subwoofer 40 is designed primarily for low capacitance, as this is a key factor in creating a tight sound. The used Complementary Conductor Technology™ is combined with a special zinc-magnesium ferrite shell to absorb very high frequency noise signals outside the sound band.

The design of QED Analoc2™ jacks helps control eddy currents, which can also affect the micro-timing of the audio signal, maintaining high accuracy from start to finish.

Main highlights:

• Conductor technology with 99.99% silver oxygen-free copper;
• Zinc-magnesium ferrite shell to absorb high-frequency noise signals;
• Low-loss polyethylene (PE) dielectric;
• 99.999% oxygen-free copper braid for 100% electromagnetic shielding coverage in coaxial geometry;
• Gold-plated QED Analoc2™ RCA jacks featuring high-purity copper contacts, a hollow center pin, and a low eddy current design.

Additional features:

• Wire cross-section: 0.30 mm ² ;
• Parallel capacitance: 124 pF/m;
• Loop resistance: 0.076 Ohm/m;
• Loop inductance: 0.33 μH;
• Dissipation coefficient at 10 kHz: 0.0210;
• Outer diameter: 6 mm.
