The Real Cable SUB-1 (5m) is an audio cable specifically designed to connect a subwoofer to an amplifier or an audio-video receiver. Developed by the French brand Real Cable, this model combines exceptional sound performance and high-quality craftsmanship to deliver an optimal listening experience for low frequencies.
The SUB-1 features meticulous construction using premium materials. Its 99.99% oxygen-free copper (OFC) conductor ensures excellent conductivity and lossless audio signal transmission. The multiple shielding effectively protects against electromagnetic interference, delivering pure, noise-free sound.
The internal geometry of the cable has been optimized to preserve signal integrity in low frequencies. This results in deep, powerful, and perfectly defined bass without dragging or blurring effects. The SUB-1 allows you to fully exploit the capabilities of your subwoofer.
At the cable’s ends, high-quality gold-plated RCA connectors are used. This premium coating ensures excellent conductivity and resistance to oxidation for long-term reliability. Real Cable’s exclusive TwistLock locking system guarantees optimal contact and eliminates any risk of accidental disconnection.
A straight connector and an angled connector provide installation flexibility, allowing you to adapt the connection to your setup. The generous 5-meter length makes it easier to position the subwoofer in the room.
True to its philosophy, Real Cable designs and manufactures the SUB-1 entirely in France. Each cable is hand-assembled and tested in the brand’s workshops, ensuring impeccable quality and reliability. This local manufacturing also allows for strict control over the materials used and the production process.
The SUB-1 comes with a lifetime warranty, a testament to Real Cable’s confidence in the durability of its products. This is a significant advantage for a long-term audio investment.
Since its launch, the SUB-1 has become a benchmark in the subwoofer cable market. Praised by audiophiles and professionals alike, it is frequently cited among the best cables in its category in comparative tests.
Its ability to deliver deep, articulate bass while maintaining dynamics and definition makes it a preferred choice for high-end home theater setups as well as two-channel audio systems. The SUB-1 allows you to get the most out of even the most powerful subwoofers.
Yes, the SUB-1 uses standard RCA connectors compatible with the vast majority of active subwoofers on the market. It can be used with any model featuring an RCA line input.
The SUB-1 is optimized for low frequencies, with reinforced shielding and high-gauge conductors. This allows it to deliver better performance than a generic RCA cable, particularly in terms of bass definition and dynamics.
It is generally recommended to use the shortest cable possible to minimize signal loss. However, the high-quality construction of the SUB-1 ensures excellent performance even at a length of 5 meters, offering greater flexibility for subwoofer placement.

In addition to being beautiful, the signal transmission is excellent. It is very easy to tuck under high-quality rugs, its price is affordable. And it’s French—cocorico.

Technology is not the most important thing. No grounding cable, but the sound is good enough for me. No interference at my place. It’s white and discreetly runs along the baseboard.
