The Ultra-Low Distortion Sub Cable
AudioQuest Sub-A subwoofer cable minimizes distortion by using identical solid Long-Grain Copper conductors for the positive and negative conductors.
Strand interaction is the greatest single source of cable distortion. Sub-A's 24 AWG solid conductors eliminate this distortion. The simpler grain structure and fewer impurities within LGC Long-Grain Copper provide significantly clearer sound than normal OFHC copper.
Gold-plated, high-conductivity plugs are attached with specially formulated AQ Solder. A foil / mylar / foil shield stops airborne noise interference.
Ground Conductor Stops Hum
While not common, sometimes there is a hum problem unless the ground of the subwoofer and ground of the receiver (or processor or preamp) are attached to each other. Sub-A includes an additional conductor with spade-lug tails at both ends of the cable. If the system has a hum problem, try attaching the lugs to the metal chassis of the subwoofer amp chassis and to the amp chassis on the sending end. Normally this extra wire will not be needed. |
