Our take on the AudioQuest SUB-1
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.

Sub-1 Series Subwoofer Cable: The AudioQuest CinemaQuest SUB-1
subwoofer cable uses three solid 2.5% Silver conductors inside PE Air Tubes. The
solid conductors eliminate any strand-interaction distortion. The PE Air Tubes
minimize information smearing caused by any solid or foam insulation. The
subwoofer cable uses single-ended (RCA plugs) that are silver-plated and
cold-welded to the cable's three conductors to insure optimum performance. The
subwoofer cable's 100% coverage shield insures noise-free performance.
Silver-Plated Copper (SPC): Silver-Plated Copper (SPC) provides
superior performance for subwoofer audio frequencies. SPC enhances the
articulation and intelligibility of low frequency information from your
amplifier to your subwoofer.
Note: Do not use the Sub-1 subwoofer cable as a full range audio
Ground Connections: If you hear noticeable hum in your system after
connecting your subwoofer, please attach the Sub-1 cable's ground leads to your
audio gear. Some
audio equipment have a ground (GND) connection on the back-panel, if not, attach the
ground spade lugs to any screw on the equipment chassis of both the source and
