Sub-X uses two identical solid 1.25% Silver-Plated Long-Grain Copper conductors for positive and negative. Solid conductors eliminate strand-interaction distortion. Foamed-PE insulation minimizes signal smearing. A 100% coverage shield ensures noise-free performance. Gold-plated high-conductivity brass plugs are attached with specially-formulated AQ Silver Solder.
SOLID 1.25% 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.
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. Sub-X uses air-filled Foamed-Polyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials.
Sub-X has identical conductors for the positive and ground connections. Underneath the 100% coverage foil shield is a bare conductor, exactly the same as the insulated center conductor. The conductor under the shield does double duty as a low distortion audio connection, and as the drain wire connecting the shield to ground.
Precision gold-plated plugs are carefully attached with the very best solder. Through choice of flux and metallurgy, AQ solder has been optimized to make a low-distortion connection. All solder, including "silver solder," is a lousy conductor. The difference you hear between solders is a result of connection quality. AQ solder does not have a high silver content because the more silver there is in solder, the more difficult it is to make a good connection.
Sometimes there is a hum problem unless the subwoofer and AV receiver (or surround-sound processor) are attached to each other using a separate wire. If your system has a hum problem, try attaching the little spade-lug tails to the metal chassis of the subwoofer amplifier and to the chassis of the sending component. Usually, this extra wire will not be needed.

Pretty satisfied with these!
I bought these along with another subwoofer cable from here, and both of them were very well made and much better than some of the other ones in the market. In fact, I purchased this one to replace one that broke after just 1 month of use.
However, I've been using these for 3 months now, and absolutely no signs of wear and tear! Amazing.
Great quality and sound!
I purchased these a while back on Amazon to replace my older cables that I must've lost while packing to move to a new place. They work great and look sturdy enough to last me for at least another ten years.
