Audioquest Boxer Subwoofer Cable

The Boxer breed originated in Germany in the late 19th century and was brought to the US after World War I. Today, Boxers are a part of the AKC’s Working Dog Group. Don’t be fooled by that “worried” look on a Boxer’s face. Boxers are known for their fun-loving, genial, and at times downright clown-like demeanor, as well as their remarkable rapport with children. However, Boxers are equally known for courage in the face of danger, or threat to family or loved ones. The Boxer’s innate intelligence, combined with its natural strength of stature, makes it a breed beloved by many.

Solid 1.25% Silver Conductors

Strand interaction is the single greatest cause of distortion in a cable. Semi-Solid Concentric Packed Conductors avoid many strand-interaction distortion mechanisms. Solid-core conductors offer a complete and compelling solution to this problem.

Conductor metal quality is critical for the best cable performance. The conductor surface is the only area of the conductor with 100% current density at all frequencies. The smoothness of the conductor surface is imperative because the surface is a guide rail for the entire energy envelope. The best copper and silver conductor metals have fewer grain boundaries and low oxygen content for low distortion and high performance.

Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated conductors are excellent for very high-frequency applications. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of high-purity silver, the performance is very close to that of a solid silver cable but priced much closer to solid copper cable. This is an incredibly cost-effective way of manufacturing very high-quality subwoofer cables.

Polyethylene Air-Tube Insulation

Insulation is necessary to keep the positive and negative conductors separate and to give stability to cable geometry. Insulation is also a "dielectric" because it is inside the conductor's magnetic field. Dielectrics absorb energy, which after a delay is then released in the signal, causing smearing and distortion. Better insulation reduces distortion by absorbing less energy.

All of Boxer’s conductors use PE Air-Tube Insulation because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. PE Air-Tube Insulation causes much less of the out-of-focus effect common to other materials.

Carbon-Based 3-Layer Noise-Dissipation System (NDS)

100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation System. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment’s ground plane.

AudioQuest’s Noise-Dissipation System (NDS) offers a compelling solution to this challenge by using metal only or alternating layers of metal and carbon-loaded synthetics to effectively “shield the shield,” absorbing and reflecting the Radio Frequency (RF) energy before it reaches the layer attached to the ground.

Boxer utilizes the Carbon-Based 3-Layer Noise-Dissipation System (NDS) to prevent most RFI from reaching the equipment’s ground plane.

Double-Balanced Geometry

Geometry is the physical relationship of the conductors to one another within a cable and determines a cable’s most basic electrical values (capacitance and inductance). Different cable applications have different/specialized geometry requirements, and so these applications do not merely follow a ‘one size fits all’ approach. Better geometry leads to lower levels of distortion.

Electrically separate shield better preserves the integrity of the negative conductor.

Directionality

AudioQuest’s understanding of conductor directionality and its effect on audio performance has steadily evolved, growing stronger and more complete. All audio cables are directional. The correct direction is determined by the arrows on the plugs or cable parts.

Cold-Welded Hanging-Silver Directly Over "Pure-Red" Copper Plugs

AudioQuest specifies materials and designs each of its own connectors from the ground up, resulting in the long-lasting quality and exceptional performance you deserve. These components are crucial to the overall performance of a cable.

To provide the best possible performance for each application, AudioQuest designs each of its connectors from the ground up. These components are crucial to the overall performance of the cable. Painstaking care is taken to evaluate the highest quality materials and design for every application.

AudioQuest pays special attention to the plating it uses over its connectors’ carefully crafted base metals. This proprietary, novel plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion instead of machine ability. Red-Copper offers a cleaner, clearer sound than the nickel-plated or OFHC metals commonly found in competing manufacturers' plugs.

This plug design enables a perfect heat-free connection between cable and plug. The connection between the plug and conductors is made using AQ’s Cold-Welded System, which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Welded System refers to a combination of high pressure at the point of contact and the use of copper- or silver-impregnated paste. (Boxer’s silver conductors get silver paste.) XLR plugs are also available.

Grounding

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.
