Features

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 cable.

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 the subwoofer.
