QED Reference Subwoofer 40 Lead

The QED Reference Subwoofer 40 Lead is a top-of-the-line cable designed to connect your subwoofer to an audio system. It guarantees the best lower-frequency sound results for home theatre or music configurations, enabling crystal-clear and powerful performance. The product’s progressive design prevents noise and distortion, thus giving the user exceptional bass reproduction.

The QED Reference Subwoofer 40 Lead is primarily for low capacitance. QED has identified this as a significant factor in producing a tight sound that retains the rhythm of the original piece, which is vital to the bottom end.

QED’s Complementary Conductor Technology, combined with a special floating Zn/Mn ferrite jacket to absorb very high-frequency noise signals outside the audible band, improves minute timing errors. The QED Analoc2 plug design helps control eddy currents, which can also affect the micro-timing of the audio signal, maintaining high fidelity from start to finish.

Award Winning Heritage

QED has won more What Hi-fi Awards than any other brand. With the Reference cable range, this heritage delivers directly and without compromise. All QED cables use the top-down principle, with Reference Subwoofer 40 representing the pinnacle of musical performance.

Floating Internal Ferrite Jacket

Absorbs high-frequency noise signal components outside the audio band. When measured using high-frequency measurement equipment, Audio 40 products convey a comparably cleaner and tighter signal pattern when their special Zn/Mn ferrite jacket is present. This benefits audio signal micro-timing and may account for the clear preference expressed for the ferrite jacket in listening tests.

Enhanced Bass for Immersive Sound

Silver-plated signal carriers, effective high-quality shielding, and low-eddy current plugs all combine to create audible sonic improvements. We urge you to compare it not only to your favourite cable but also to alternative brands and models at any price!

All-new Analoc2 connector design

The Reference Subwoofer 40 Analoc2 design still features low-bulk, high-purity copper connectors alongside low-mass metal barrels, but it now cleverly substitutes high-rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the detrimental effects of eddy currents.

Although already smaller than in traditional bulk brass plugs, these unfavourable currents could still circulate weakly in the isolated metal body of the previous plug design.  To complete the RCA plug’s Analoc2 upgrade and help combat the skin effect. The hollow, gold-plated, high-purity copper signal pins are retained.

Complementary Conductor Technology

Improves timing and detail, retaining the rhythm of the original piece—vital when it comes to the “bottom end.” Unlike conventional analogue interconnects, Reference Audio 40 uses two silver-plated 99.999% Oxygen-Free Copper conductors of different diameters to carry the same audio signal.

This provides an alternative signal path for more subtle audio components that might otherwise become time-smeared in a single audio pathway. Reference Subwoofer 40 further optimises by having a 25% smaller diameter than Reference Audio 40, making it more convenient for those long runs around the room.

Extremely Clear Bass Performance

The QED Reference Subwoofer 40 Lead was formatted to reproduce accurate and deep bass. This tremendously affects the subwoofer’s ability to generate low-frequency sounds with precision and clarity, making the listener experience a loud sound. Each time you play music or watch a movie, you will get loud sound.

Features and Benefits

Summary of the QED Reference Subwoofer 40 Lead

The QED Reference Subwoofer 40 Lead guarantees high-quality bass performance. Its innovative design makes your subwoofer the perfect device for providing the best sound for movies, music, and home theatre.

Unimpeded Performance

The most up-to-date shielding of the subwoofer link is used. It keeps the signal clean and transmits it noiselessly, which is how the subwoofer shows its true nature.

Trustworthy design and construction

In this case, the product’s initial condition assures that the cable is equipped with impregnable construction, multi-purpose contacts, and rust-proofing. This gives healthy and long-lasting performance and ensures product reliability. The substantial return will come eventually.
