About 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.
Product highlights:
- three silver-plated solid copper conductors (silver layer is 2.5% of total conductor)
- PE Air Tubes minimize information smearing
- 100% coverage shield for noise-free signal transfer
- cold-welded silver-plated RCA connectors
- textile braid cable cover

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.

This sub cable is a great improvement over a cable I had been using for about 10 years. The bass is a lot more tight and much more tuneful than the old cable. This sub cable was worth the price for me.
