AudioQuest Boxer Subwoofer Cable - 2.0 Meter - RCA

AudioQuest Boxer Subwoofer Cable — 2.0 Meter — RCA

What It Does in Your System

Built for the One Job Most Cables Treat as an Afterthought

The cable from your receiver or preamp to your subwoofer usually gets the least attention in the system. It often runs along a wall, near power cords, and it carries a signal that has to stay clean and well timed to keep bass sounding tight.

Boxer is AudioQuest's subwoofer cable built specifically for that run. At 2 meters — about 6.5 feet — it suits a subwoofer placed near the rack or beside the front speakers.

Silver-Plated Copper Conductors

Boxer uses solid copper conductors plated with 1.25% silver. Solid wire avoids the strand interaction that AudioQuest identifies as a distortion source in ordinary stranded cable.

AudioQuest is unusually direct about why silver plating suits this application. They describe the effect as sharpening articulation — helpful for a subwoofer, where you want to hear the shape of a bass note rather than a general rumble.

Air-Tube Insulation and Carbon Shielding

Any material touching a conductor absorbs a little energy and releases it late, which smears timing. AudioQuest addresses this with Polyethylene Air-Tube insulation, which surrounds each conductor mostly with air.

Around that sits a Carbon-Based 3-Layer Noise-Dissipation System. Full shield coverage is easy to achieve; what AudioQuest works on is draining the noise it collects away from where it would cause trouble.

Is This Right for You?

Check these before ordering:

• Your subwoofer has a single LFE input. This is a single RCA cable, one plug at each end. If your subwoofer has two inputs labeled L and R, you want the Y-cable version instead.
• Measure the real route. Two meters is about 6.5 feet, and cable follows walls and furniture rather than straight lines. Add slack, and when you are between two lengths, take the longer one.
• Match it to your system. Boxer suits a good home theater or a serious 2.1 setup feeding a quality powered subwoofer. In an entry-level system, the money is usually better spent elsewhere first.

Setup & Installation

Connect one end to the subwoofer output on your receiver, processor, or preamp — often labeled SUB OUT or LFE. Connect the other to the LFE or line input on the subwoofer.

Route the cable away from power cords where you can. If they must meet, cross them at a right angle rather than running them side by side, which picks up less noise. Leave a little slack at each end so nothing pulls on the connector.

Features & Specifications

Solid 1.25% Silver-Plated Copper Conductors
Solid rather than stranded wire, plated with silver to sharpen articulation in the bass region.

Polyethylene Air-Tube Insulation
Surrounds each conductor largely with air, which absorbs and releases far less energy than solid insulation.

Carbon-Based 3-Layer Noise-Dissipation System
Three layers of shielding designed to drain radio-frequency noise away from the signal path.

Cold-Welded RCA Plugs
Silver over pure copper, joined without solder, so there is no second metal in the signal path at the connection.

Frequently Asked Questions

Do I need one cable or a Y-cable?
Look at your subwoofer's inputs. A single jack marked LFE takes this cable. Two jacks marked L and R take the Y-cable version, which splits one plug into two. Using a Y-cable on a single LFE input gains you nothing.

Does cable quality matter for bass?
Bass frequencies are low, but the signal still passes through a long unbalanced run next to power wiring, where it can pick up hum and noise. Shielding is the part that earns its keep here. The conductor and insulation choices affect how cleanly the timing of a note comes through.

What if 2 meters is not quite enough?
Boxer comes in several longer lengths. Rather than stretching a cable tight or adding a coupler, order the next size up — a taut cable at the connector is the most common cause of an intermittent subwoofer.
