Audioquest Irish Red RCA Low-Frequency Subwoofer Audio Cable
Connect amplifiers, receivers, soundbars, and AVRs to a broad range of subwoofers with this AudioQuest Irish Red RCA subwoofer cable. Solid 0.5% Silver conductors minimize distortion, Foamed-Polyethylene preserves dynamic contrasts, and a Metal-Layer Noise-Dissipation efficiently dissipates high-frequency noise. The result is clearer, naturally beautiful music, intelligible dialog, and thrilling sound effects.

Key Technologies
SOLID 0.5% SILVER CONDUCTORS
Solid .5% Silver-Plated Copper Conductors: A superbly cost-effective way to turn up the “sharpness” for a subwoofer, enhancing articulation and intelligibility.
Metal-Layer Noise-Dissipation
It's easy to accomplish 100% shield coverage. Preventing captured radio-frequency interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation. Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. Noise-Dissipation "shields the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
Foamed-Polyethylene Insulation
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
Symmetrical Coax Geometry
Identical positive (+) and negative (-) conductors prevent the shield from being used as an inferior audio conductor.
Cold-Welded, Gold-Plated Terminations
This plug design allows for a connection devoid of solder, which is a common source of distortion. Instead of solder, the process employs a high-pressure technique. Because the ground shells are stamped instead of machined, the metal used can be chosen for low distortion instead of machinability.
- Solid .5% Silver Conductors: Solid conductors help eliminate strand-interaction distortion and reduce jitter.
- Compatible with most subwoofers: For wide-ranging use.
- 0.5% silver-plated copper material: Helps prevent signal distortion.
- Nitrogen-injected insulation: Reduces timing errors and soundstage smearing.
- Metal-layer noise-dissipation system: Minimizes RF and EMI noise before reaching the equipment ground plane.

Q What is the Audioquest Irish Red RCA cable used for?
It's a subwoofer cable designed to connect amplifiers, receivers, soundbars, or AV receivers to a subwoofer while minimizing distortion and noise.
Q How do the Irish Red's conductors improve sound quality?
It uses solid 0.5% silver conductors, which prevent strand-interaction distortion — a common source of dynamic distortion — resulting in better articulation, intelligibility, and reduced jitter.
Q What is symmetrical coax geometry, and why is it used here?
It's a cable construction that keeps the shield from acting as an inferior secondary audio conductor, helping preserve signal integrity.
Q How does the cable's shielding protect against interference?
A metal-layer noise-dissipation system absorbs and reflects most radio-frequency interference before it reaches the ground layer, preventing it from distorting the signal.
Q What role does the insulation play in the cable's performance?
The foamed-polyethylene insulation has high air content, which minimizes energy absorption and contributes to clearer audio reproduction.
