SUB-X SUBWOOFER INTERCONNECT Chassis Ground Wire 1.25% Silver Conductors Gold-Plated, AQ Solder • 1.25% Silver Conductors • Identical +/- Conductors • Chassis Ground Wire Identical +/Conductors SUB-X uses two identical solid 1.25% Silver conductors for positive and negative. Solid conductors eliminate strand-interaction distortion. Foam PE insulation minimizes information smearing. A 100% coverage shield insures noise-free performance. Gold-plated high-conductivity brass plugs are attached with specially formulated AQ Silver Solder. Silver-Plated Copper (SPC) always provides superior performance for video and digital audio. Unfortunately, when used for full range analog audio, the discontinuity of plating silver over copper causes high frequencies to sound edgy and harsh. However, when used only for subwoofer frequencies, SPC's "artificial edge" actually enhances the articulation and intelligibility of low frequency information. Do not use Sub-X as a full range audio cable. DIRECTIONS: Sometimes there is a hum problem unless the subwoofer and receiver (or processor) are attached to each other through a separate wire. If your system has a hum problem, try attaching the little spade-lug tails to the metal chassis of the subwoofer amp and to the chassis of the sending component. Usually, this extra wire will not be needed.
