AudioQuest Irish Red Subwoofer Cable at Vinyl Sound Toronto Canada

The Irish Red is a dedicated subwoofer interconnect cable from AudioQuest (San Jose, California, USA), available at Vinyl Sound in Toronto, Canada. Part of AudioQuest's purpose-built subwoofer cable lineup, the Irish Red sits above the entry-level Black Lab and steps up with Solid 0.5% Silver-Plated Copper conductors for improved articulation and low-frequency definition. It combines AudioQuest's proprietary Metal-Layer Noise-Dissipation System (NDS) and Symmetrical Coax Geometry to deliver a tighter, quieter, and more controlled bass signal between an AV receiver, preamplifier, or surround processor and any powered subwoofer.

Solid 0.5% Silver-Plated Copper Conductors

The Irish Red uses solid conductors in which a precise 0.5% silver surface is applied to AudioQuest's Long-Grain Copper (LGC) base. Because high-frequency signals travel almost exclusively on the outermost surface of a conductor, the silver layer performs close to a solid silver cable in the frequency ranges that govern subwoofer articulation, transient definition, and noise-floor behavior. Solid construction eliminates strand interaction entirely, one of the most common causes of dynamic blurring and a bloated, poorly defined low end in multi-strand cable designs. The result is tighter transients, a more controlled bass presentation, and a lower noise floor without the cost of a pure solid-silver cable.

Metal-Layer Noise-Dissipation System and Symmetrical Coax Geometry

Conventional subwoofer cables capture radio-frequency interference (RFI) through their shields and drain it directly to the component ground plane, where it modulates the audio reference and introduces distortion into the bass signal. AudioQuest's Metal-Layer Noise-Dissipation System addresses this by absorbing and reflecting most RFI energy at the shield itself before it ever reaches the ground layer, keeping the ground reference clean and the subwoofer signal undistorted. The Symmetrical Coax Geometry ensures that the positive and negative conductors are identical in construction, preventing the shield from being pressed into service as an inferior audio conductor and maintaining consistent impedance throughout the full cable run.

Key Features

• Solid 0.5% Silver-Plated Copper Conductors: A solid Long-Grain Copper base with a high-purity silver surface layer delivers performance close to solid silver for subwoofer-range signals, eliminating strand-interaction distortion for tighter, more articulate bass.
• Metal-Layer Noise-Dissipation System (NDS): Absorbs and reflects RFI at the shield before it reaches the ground layer, preventing noise contamination of the subwoofer's ground reference and lowering the system noise floor.
• Foamed-Polyethylene Insulation: The high air content of Foamed-PE minimizes dielectric energy absorption and its associated distortion, preserving the dynamic impact and timing accuracy of low-frequency transients.
• Symmetrical Coax Geometry: Identical positive and negative conductors maintain consistent impedance throughout the cable run and prevent the shield from acting as a secondary audio conductor, which degrades signal purity.
• Cold-Welded, Gold-Plated RCA Plugs: High-pressure cold-welding eliminates solder at the termination point, removing a common source of distortion and corrosion. Gold plating ensures a low-resistance, reliable connection that remains consistent over time.
• RF-Noise Direction Control: All internal conductors are direction-controlled to further minimize RF noise contribution from the cable into the system.
• Built-In Grounding Tail with Spade Lugs: A dedicated ground wire with spade-lug terminations is included to eliminate hum caused by ground loops between the subwoofer amplifier and the sending component.
• Braided Textile Jacket: The red-and-black braided jacket covers lengths of 5 meters and under, providing durability and a clean appearance. Lengths of 8 meters and above use a smooth PVC jacket rated for in-wall installation (CL3/FT4).

Frequently Asked Questions

What is the AudioQuest Irish Red subwoofer cable?

The AudioQuest Irish Red is a dedicated single-ended subwoofer interconnect cable that connects the LFE or subwoofer output of an AV receiver or preamplifier to a powered subwoofer via RCA. It uses Solid 0.5% Silver-Plated Long-Grain Copper conductors, Symmetrical Coax Geometry, and a Metal-Layer Noise-Dissipation System to deliver tighter, lower-distortion bass with a quieter noise floor than generic subwoofer cables.

How does the AudioQuest Irish Red compare to the Black Lab and Boxer subwoofer cables?

The AudioQuest subwoofer lineup progresses from the Black Lab through the Irish Red to the Boxer, with each model adding increasing silver content to the conductor. The Black Lab uses Solid Long-Grain Copper (LGC) conductors with no silver layer, making it an excellent entry-level choice. The Irish Red steps up to a 0.5% silver-plated surface on the same LGC base, improving articulation and transient definition at the subwoofer's operating frequencies. The Boxer takes silver content further and adds a more advanced noise-dissipation implementation. For most home theatre and stereo subwoofer applications, the Irish Red represents a strong mid-tier balance of materials quality and sonic performance.

Can the AudioQuest Irish Red eliminate subwoofer hum?

Yes, the Irish Red includes a built-in grounding tail with spade-lug terminations specifically designed to resolve ground-loop hum between a subwoofer amplifier and the sending component. Attaching the spade lugs to the metal chassis of both the subwoofer and the AV receiver or preamplifier provides a dedicated ground path that prevents the hum without affecting the audio signal. This feature is not present on most generic subwoofer cables.

What is AudioQuest's Metal-Layer Noise-Dissipation System?

AudioQuest's Metal-Layer Noise-Dissipation System (NDS) is a shielding technology that goes beyond standard 100% shield coverage. Conventional cable shields capture radio-frequency interference and route it to ground, where it contaminates the audio reference and raises the noise floor. The NDS absorbs and reflects most of that RFI energy at the metal layer itself before it reaches the ground plane, keeping the subwoofer's signal path and ground reference cleaner for lower distortion and blacker backgrounds.

What subwoofers and receivers is the AudioQuest Irish Red compatible with?

The Irish Red is compatible with any powered subwoofer and any AV receiver, stereo preamplifier, or integrated amplifier that uses standard RCA connectors for its LFE or subwoofer output. This includes subwoofers from SVS, REL, JL Audio, Paradigm, Velodyne, Klipsch, MartinLogan, and Sonance, and receivers and processors from Denon, Marantz, Yamaha, Anthem, and Arcam, among others.

Where can I buy the AudioQuest Irish Red subwoofer cable in Toronto or Canada?

The AudioQuest Irish Red subwoofer cable is available at Vinyl Sound, an authorized AudioQuest dealer in Toronto, Canada. Vinyl Sound carries multiple lengths of the Irish Red and can assist with system matching and cable length recommendations for customers throughout the Greater Toronto Area and across Canada.

Does the AudioQuest Irish Red work for in-wall subwoofer installations?

Yes, the Irish Red is available in longer lengths of 8 meters and above with a smooth PVC jacket rated CL3/FT4 for in-wall installation. Lengths of 5 meters and under use the standard red-and-black braided textile jacket suited for exposed runs. For custom installation projects in the Toronto area, Vinyl Sound can advise on the appropriate length and jacket type for your room layout.

Is the AudioQuest Irish Red suitable for both stereo and home theatre subwoofer setups?

Yes, the Irish Red is equally effective in stereo two-channel systems and full home theatre configurations. In a stereo system it connects the subwoofer output of an integrated amplifier or stereo preamplifier to a powered sub. In a home theatre setup it carries the LFE channel from an AV receiver or surround processor to one or two subwoofers. For dual-subwoofer home theatre installations, two Irish Red cables are recommended for individual, independent subwoofer control.
