Know before you buy
Perfect Surface Copper (PSC+) undergoes a specialized drawing process that creates an ultra-smooth surface. This minimizes grain boundaries and impurities within the metal, which helps reduce signal distortion and allows for cleaner, more detailed bass reproduction.
Silver is an exceptionally conductive material. Plating the RCA-800 connectors with silver ensures a low-resistance connection between your subwoofer and receiver, helping to maintain signal integrity across the entire length of the cable.
Yes, this cable is 20 meters long, making it an excellent choice for large home theater setups where the subwoofer is placed a significant distance from the audio source. The high-quality conductors are designed to maintain signal strength over this extended length.
Beyond its aesthetic appeal, the nylon braided jacket provides a durable, protective layer for the cable. It helps prevent kinking and protects the internal conductors from physical wear and tear during installation.
Custom-termination means that each cable is hand-assembled and finished by a technician rather than being mass-produced on an automated line. This ensures a precise, high-quality connection at the plug that is built to last.
