AUDIOQUEST Irish Red RCA Subwoofer Cable

The AudioQuest Irish Red RCA subwoofer cable is engineered for outstanding low-frequency performance, designed to connect amplifiers, AVRs, soundbars, and receivers to a variety of subwoofers. The combination of Solid 0.5% Silver conductors minimizes distortion while Foamed-Polyethylene insulation ensures dynamic contrasts are preserved. The Metal-Layer Noise-Dissipation technology works to reduce high-frequency noise, resulting in a clear, vibrant, and immersive listening experience with every deep, powerful bass note.

Solid 0.5% Silver Conductors
The use of 0.5% silver-plated copper conductors provides a significant performance boost for subwoofers by enhancing the clarity and detail of the audio. Silver, being one of the best conductors of electricity, allows for higher-frequency signals to travel more effectively along the conductor’s surface, reducing distortion and improving the overall sharpness of the sound. This subtle enhancement is especially beneficial for subwoofers, as it adds precision to the low-frequency response, ensuring better articulation and intelligibility in bass-heavy tracks. With a relatively small percentage of silver, the cost-to-performance ratio is optimized, making it an excellent choice for those seeking high-quality sound without breaking the bank.

Metal-Layer Noise-Dissipation
Traditional shield systems are designed to absorb and drain radio-frequency interference (RFI) to the ground, but this process can inadvertently distort the signal. AudioQuest’s Noise-Dissipation technology takes a different approach. Instead of simply absorbing the RFI and sending it to ground, this system “shields the shield,” using alternating layers of metal and carbon-loaded materials. These layers absorb and reflect the majority of the RFI energy, preventing it from ever reaching the ground reference. By maintaining the integrity of the ground plane and reducing distortion, Noise-Dissipation ensures that the subwoofer receives a cleaner, more accurate signal for enhanced bass performance and clarity.

Foamed-Polyethylene Insulation
Foamed-Polyethylene (Foamed-PE) insulation is a highly effective solution for minimizing distortion in audio cables. Unlike traditional insulation materials, which can absorb energy and release it as unwanted distortion, Foamed-PE features a high air content that significantly reduces this effect. The minimal energy absorption of air ensures that the signal remains as pure and unaltered as possible. Polyethylene itself is low-loss and has a benign distortion profile, allowing for more natural and focused sound reproduction. In subwoofer applications, this means that dynamic contrasts are preserved, and the low frequencies are delivered with greater clarity and impact, without the muddiness or loss of definition that can occur with inferior insulation materials.

Symmetrical Coax Geometry
Symmetrical Coax Geometry ensures balanced signal transmission by using identical positive (+) and negative (-) conductors. This design eliminates the need for the shield to carry any signal, ensuring that it doesn't become an inferior conductor, which could degrade the audio quality. By treating the positive and negative conductors equally, this geometry reduces the risk of imbalance or distortion, allowing for a cleaner, more accurate signal transfer. The result is enhanced signal integrity, reduced noise, and overall superior performance, especially when dealing with high-frequency audio signals that require precise delivery to the subwoofer.

Cold-Welded, Gold-Plated Terminations
The terminations on this cable utilize a cold-welding process, ensuring a connection free of solder, which can often introduce distortion into the audio signal. This advanced method uses high pressure to create a solid bond between the conductor and the plug, preserving the integrity of the signal path. Unlike traditional connectors, where the metal is often chosen for ease of machining, the stamped ground shells in this design allow for the selection of metals that are optimized for low distortion, resulting in cleaner, more precise audio performance. The gold plating enhances corrosion resistance, ensuring the long-term reliability and consistent performance of the connection, while reducing the potential for signal degradation over time.
