The Real Cable SUB-1 (3m) is a premium audio cable specifically designed to connect your subwoofer to your audio system. Developed by the French brand Real Cable, this subwoofer cable ensures optimal low-frequency transmission for an immersive sound experience.
The SUB-1 features a sophisticated technical design, making it a benchmark cable in its category. Its conductors are made from 99.99% oxygen-free copper (OFC), ensuring exceptional signal purity. The bi-metal technology, combining copper and silver, significantly enhances high-frequency transmission.
The cable also incorporates multi-section strands, ensuring consistent propagation time across low and high bass frequencies. This results in a noticeable improvement in precision and bass attack, which are crucial for subwoofer performance.
To ensure interference-free signal transmission, the Real Cable SUB-1 is equipped with triple shielding. This effective protection against noise guarantees a pure sound, free from unwanted disturbances.
The connectors are equally impressive, featuring 24-carat gold-plated monoblock TwistLock® metal plugs. This twist-lock system ensures optimal and durable contact. A straight plug and an angled plug provide appreciated flexibility during installation.
Using the SUB-1 leads to a significant improvement in your system’s audio quality. Low frequencies gain depth and definition, allowing you to fully experience the impact of explosions in action movies or the richness of bass notes in your favorite music tracks.
The enhanced precision of bass attacks ensures better sound articulation, avoiding the “muddy sound” effect often associated with lower-quality cables. The result is a more natural and balanced sound, where every note finds its place.
Real Cable demonstrates its confidence in the quality of its products by offering a lifetime warranty on the SUB-1. This assurance reflects the cable’s durability and reliability, designed to stand the test of time.
Investing in a cable of this quality makes perfect sense for a high-end audio setup. It allows you to fully exploit the potential of your subwoofer and your audio system as a whole.
The SUB-1 is the result of French expertise in high-end audio. Designed and developed in France, it benefits from a rigorous manufacturing process, including hand-soldering to ensure impeccable finishing.
This attention to detail is evident in every aspect of the cable, from the quality of the materials used to the precision of the assembly. This excellence has enabled Real Cable to establish itself as a reference in the audio cable market in less than a decade.
The 3-meter length of the SUB-1 is suitable for most home setups. It provides enough flexibility to optimally position the subwoofer in the room without being excessively long, which could risk signal degradation.
Yes, the SUB-1 is equipped with standard RCA connectors, making it compatible with the vast majority of subwoofers and amplifiers on the market.
While the cable is designed to work in both directions, it is recommended to follow the direction indicated on the sheath for the best possible performance.
Avoid excessive bending or subjecting the cable to tension. Occasionally cleaning the connectors with a soft cloth is usually sufficient to maintain good performance over the long term.
Although the SUB-1 is designed for high-end systems, it can bring noticeable improvements even to more modest setups, particularly in terms of bass frequency precision.

Quality product at an attractive price.
It’s nice and white, so it’s quite visible.

Bought a pair to connect a Kef xq60b subwoofer, replacing a temporary setup of 6 excellent RCA cables joined with adapters.
Designed in France but made in China, a bit disappointed about that. Nice quality for these white cables (better for sound). Didn’t notice any particular improvement compared to my DIY setup, but no loss either.
Good product.
