Detailed Description
Award-winning Heritage
QED, with its numerous What Hi-fi Awards, leverages its extensive experience in cable technology to deliver uncompromised performance through the Reference Subwoofer 40. This product embodies the pinnacle of musical performance.
Floating Internal Ferrite Jacket
The Zn/Mn ferrite jacket absorbs high-frequency noise signals outside the audible band, ensuring a cleaner and tighter signal pattern. This significantly improves audio signal micro-timing and overall sound quality.
Just Listen
Silver-plated signal carriers, effective shielding, and low eddy current plugs combine to enhance sonic performance. QED encourages comparison with other cables, emphasizing the audible improvements provided by these technologies.
All-new Analoc2™ Connector Design
The Analoc2™ connectors feature low bulk, high-purity copper alongside high rigidity thermoplastic materials to eliminate eddy currents. This results in reduced distortions and improved fidelity of the audio signal.
Complementary Conductor Technology
This technology uses two silver-plated 99.999% Oxygen Free Copper conductors of different diameters to carry the same audio signal. This method retains the rhythm and detail of the original piece, vital for subwoofer performance. The Reference Subwoofer 40 has a smaller diameter than its counterparts, making it more convenient for long runs around a room.
