AudioQuest Husky Subwoofer Cable - 2.0 Meter - RCA to RCA - Single

What You Need to Know

What Is a Subwoofer Cable, and Why Use One Designed for the Job?

A subwoofer cable is an RCA interconnect — a single conductor with a shield around it and an RCA plug at each end. What makes a “subwoofer cable” different is what it has to put up with.

The signal it carries is the LFE channel — Low Frequency Effects, the dedicated low-frequency mono signal a home theater receiver, processor, or 2-channel preamp sends to a powered subwoofer. The run is usually long, and the path often passes close to AC and to the subwoofer’s own switch-mode power supply.

A cable engineered for that job uses heavier shielding and rugged connectors. Mechanically, the Husky can also be used as a regular RCA interconnect anywhere else in your system.

Where Does This Cable Belong in the AudioQuest Subwoofer Line?

The Husky sits at the top of AudioQuest’s dog-named subwoofer cable family — the line goes Black Lab, Greyhound, Irish Red, Boxer, Husky. The Husky is the only cable in the family to use Perfect-Surface Copper+, AudioQuest’s highest-purity copper grade, alongside Carbon-Based shielding and the patented 72V Dielectric-Bias System.

What’s Different About This One?

The Husky uses solid Perfect-Surface Copper+ conductors. PSC+ is AudioQuest’s highest-purity copper grade — the same surface-smoothing process used for Perfect-Surface Copper, applied to a more refined copper feedstock. Solid-core construction means a single piece of copper rather than many small strands, eliminating strand-to-strand interaction in the conductor.

The dielectric — the insulation surrounding the copper — is a polyethylene air-tube. The conductor sits suspended inside a tube of polyethylene, with air around most of its length. Air is the lowest-loss dielectric available short of vacuum.

The shield is the Carbon-Based Noise-Dissipation System (NDS) — a carbon-loaded layer that absorbs radio-frequency noise picked up by the cable instead of letting that noise drain back into the audio circuit’s ground. Critical for a long cable that passes close to AC and to the subwoofer’s own switch-mode power supply.

The RCA terminations are silver-plated and cold-welded. Cold-welding bonds the conductor to the connector under high pressure rather than soldering — no flux residue, no eutectic alloy in the signal path, and a mechanically stable joint that doesn’t relax over time.

Bill Low founded AudioQuest in 1980, and his “Do No Harm” philosophy still drives the line — the cable’s first job is to get out of the music’s way.

DBS Explained — The 72V Dielectric-Bias System

The Husky carries AudioQuest’s patented Dielectric-Bias System (DBS) — a small battery pack on the cable that applies a constant 72-volt electrostatic field to the dielectric (the insulation around the conductors). The idea is to polarize the dielectric so it doesn’t absorb and re-release small amounts of energy back into the signal as the audio current changes.

DBS is patented (US Patent #7,224,108). The battery pack has a test button with an LED on it, so you can confirm the battery is alive at any time — just press the button and look for the light. Battery life is rated for multiple years of normal service. AudioQuest specifies the exact rating on the Husky’s manufacturer page; verify the current rating there.

Where Does This Cable Belong in Your System?

The Husky is matched to reference and near-reference home theater systems and high-end 2.1 setups, where the chain around the subwoofer cable justifies AudioQuest’s most refined dog-named cable.

• Good fit: reference home theater systems, high-end processor LFE-out feeding a reference-grade powered subwoofer, 2-channel preamp sub-out feeding a 2.1 subwoofer in a high-end chain.
• Not ideal: entry or mid-tier systems where Boxer or Irish Red would be a better fit for the chain around the subwoofer.
• Different configuration? If your subwoofer has two RCA inputs labeled L and R, you want the Husky Y-cable version instead.

Single Sub or Dual Subs?

Most home theater subwoofers have a single RCA input labeled “LFE.” A standard single-end subwoofer cable like this one connects directly. Some subs — particularly REL models and certain 2-channel-music-focused designs — have stereo L/R RCA inputs that internally sum to mono. For those, the Y-cable version is the natural choice.

Single-End or Y-Cable — Which One Do I Need?

The answer comes down to what’s on the back of your subwoofer. Most home theater subs have a single RCA input labeled “LFE” — single-end is what you want. Some subs (REL and certain 2-channel-music subwoofers) have stereo L/R RCA inputs that internally sum to mono — for those, the Y-cable version is the right choice.

Frequently Asked Questions

What does a subwoofer cable actually do?

Carries the LFE channel from receiver/processor/preamp to powered subwoofer. Engineered for long runs in noisy AV environments.

Can I use a regular RCA interconnect instead?

A well-built regular RCA will work mechanically. The Husky adds PSC+ conductor, Carbon-Based shielding, 72V DBS, silver-plated cold-welded RCAs, and long lengths specifically for subwoofer service.

What length do I need?

Measure the actual cable route, not straight-line distance. Add slack. When in doubt, go one length up.

What if my sub has two RCA inputs (L and R)?

You want the Y-cable version of the Husky.

How long does the DBS battery last?

Multiple years of normal service. Press the test button on the battery pack — if the LED lights, the battery is alive. The pack is replaceable.

How does this compare to the Boxer below it?

Same technologies — Carbon-Based NDS, 72V DBS, PE air-tube dielectric, silver-plated cold-welded RCAs. The Husky steps the conductor up from PSC to PSC+, AudioQuest’s highest-purity copper grade.

What’s the warranty?

Non-transferable, original-owner limited lifetime warranty. Audio Advisor is an authorized AudioQuest dealer.
