4.5M black/red subwoofer interconnect cable

You need a cable specifically for your subwoofer, but you also insist that it be constructed of high-quality, distortion-reducing materials—without breaking the bank. AudioQuest's SubX is the perfect match. And as a component, these cables will drastically improve the quality of sound and video of every other component in your home-theater quiver. Really.

AudioQuest: Invest in the best

You're looking for a speaker cable with superior signal transmission and a smooth, clear sound. But you want a high-quality cable—and there's a plethora to choose from—so what could possibly make AudioQuest cables that much more superior? Well, let me tell you. These cables are babied. They're coddled. Each cable's hand is held from its conception in Bill Low's head until it is carefully swaddled in product packaging and shipped off to your home.

For your listening pleasure

The SubX utilizes the large, 22-AW gauge conductor to ensure distortion stays at a minimum and takes performance up a notch by using a solid silver-plated copper conductor (1.25-percent silver). Silver-plated copper 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, silver-plated copper's "artificial edge" actually enhances the articulation and intelligibility of low frequency information. (Do not use SubX as a full range audio cable.)

The constancy of superb solder

Just as cable technology relies on minimizing distortion, so does solder. Using the most appropriate flux and precise metallurgy, AudioQuest solder has been optimized to make a low-distortion connection. All solder, including silver, is a poor conductor. The difference you hear between solders is a result of connection quality. AudioQuest 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. (Though quite the opposite is true when it comes to using silver conductors.)

A dielectric that would make mom proud

Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation, circuit board materials—all absorb energy (loss). Some of this energy is stored and then released as distortion. The general cable industry ranks insulating materials by loss, with little regard for distortion. AudioQuest ranks materials by damage to an audio signal. The Sub-X uses air-filled Foam Polyethylene (FPE) insulation on both conductors because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile—these are good things: thanks to all the air in FPE, it causes much less of the out-of-focus effect common to other materials.

Damage control—let's compare apples. . .

It's important to know that an audio or video signal cannot be improved upon—it's as good as it's going to get once it leaves your amp, DVD player, whatever component you're running. So why bother with a high-end cable? Simple: the signal can't be improved, but it can be damaged. Significantly. A lesser-quality cable leaves your signal wide-open to instabilities. A lesser-quality cable is constructed of bundled, twisted strands of conductive material—up to 200 to 2000 strands per bundle. And as the signal wants to travel the path of least resistance (down the outside of the bundle), all those twisted strands inhibit the signal. They draw the signal from the outside of the bundle to the inside, where it fights to get back to the outside again. What's the result? Distortion. Lost data. Poor sound quality.

. . .to oranges

AudioQuest, on the other hand, engineers their cables with the highest quality, perfectly gauged solid-core, copper and silver conductors. And each conductor strand is slowly and precisely loomed, not twisted, into the final cable bundle—and it's important to note that the maximum amount of strands AudioQuest has used in their longest cable, for flexibility requirements, is 32 (that's a few less than 200, and a lot less than 2000). Once they have constructed the conductor, AudioQuest wraps it in the dielectric (a fancy word for the insulating material) to keep the cable at peak performance levels at all times by absorbing as little energy as possible in order to avoid the reintroduction of energy (distortion) back into the conductor.

The bottom line

What AudioQuest is doing is engineering cables with conductors that have all the proper attributes, for decreased distortion. They've arranged the conductors so the signal travels down a straight path, for decreased distortion. They've wrapped the conductor metal in a non-conductive material, to decrease distortion. The result is an astonishingly pure, very stable signal. Starting to make sense? AudioQuest loathes distortion. You'll love AudioQuest.
