AudioQuest's SUB-1 cable delivers clean, clear bass to your high-performance powered subwoofer. This triple-balanced cable features three identical conductors for clean signal transfer. Each conductor is a single, unbroken strand of 2.5% silver. Solid conductors eliminate electrical and magnetic interference that can add brittleness to the sound with multi-strand conductor cables.
Air tube insulation and shielding
Each conductor has its own insulating air tube, which prevents information smearing better than foam insulation. An additional layer of shielding virtually eliminates electronic noise, for the cleanest signal possible.
High-quality connectors eliminate the weakest link
The SUB-1 features RCA connectors made of silver-plated copper. Although this same material can sometimes cause high frequencies to sound edgy with full-range analog audio signals, it actually improves bass articulation when used in subwoofer cables. The connectors are fastened by cold welding — a process that uses high pressure and silver paste to minimize signal loss. By contrast, solder tends to impede the signal, and heating the copper conductor can negatively affect its performance.
