Focused Signal Transfer for Low Frequencies

At the core of the NF-B is a massive inner conductor designed specifically for transmitting subwoofer frequencies. Composed of ultra-fine OFC copper strands, this conductor ensures precise bass response without smearing or loss of definition. A surrounding dielectric insulation layer maintains signal integrity and minimizes energy loss.

Triple-Layer Shielding

The NF-B features VIABLUE™'s Triple-Shield technology, which includes two contra-rotating spiral shields made of both tinned and pure OFC copper, as well as a semiconducting LDPE layer. This configuration eliminates interference, ensures a black background, and provides effortless dynamic performance—even at high volume.

Custom Connectors and EMI Protection

The cable is terminated with VIABLUE™’s in-house engineered T8 RCA connectors, finished in 24-carat gold plating for lasting conductivity and contact stability. The integrated Ferrite Filter 9 suppresses high-frequency EMI, ensuring that your subwoofer receives only pure, unadulterated signal free from external noise.

Made in Germany

All VIABLUE™ cables are handcrafted and assembled in Germany by skilled technicians. Every NF-B Subwoofer RCA Cable undergoes rigorous quality control to ensure flawless construction, sonic transparency, and long-term reliability. From precision shielding to the immaculate termination of each connector, VIABLUE™'s German engineering ethos is evident in every detail, delivering professional-grade performance for discerning audiophiles.
