AudioQuest Sub Series 3 Subwoofer Interconnect Cable 9M / Audioquest

Sub-3 uses three solid 6.1% Silver-Plated Long-Grain Copper conductors inside PE Air-Tubes. Solid conductors eliminate strand-interaction distortion. PE Air-Tubes minimize signal smearing caused by any solid or foam insulation. The 72V Dielectric-Bias System (DBS) almost eliminates remaining insulation-induced distortion. Three conductors ensure optimum-performance RCA plugs or XLR plugs. A 100% coverage shield ensures noise-free performance.SOLID 6.1% SILVER-PLATED LONG-GRAIN COPPER CONDUCTORS: Silver-Plated Copper always provides superior performance for video and digital audio. Unfortunately when used for full-range analog audio, the discontinuity of silver plating over copper causes high frequencies to sound edgy and harsh. However, when used only for subwoofer frequencies, Silver-Plated Copper's "artificial edge" actually enhances the articulation and intelligibility of low-frequency information. Do not use AudioQuest's Silver-Plated Copper subwoofer cables for full-range audio.POLYETHYLENE AIR-TUBE INSULATION: Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. All of Sub-3's conductors use PE Air-Tube Insulation because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. PE Air-Tube Insulation causes much less of the out-of-focus effect common to other material
