Low-Distortion & Low-Noise Star-Quad Speaker Cables

The speaker cable model Type 4 was first introduced about 1983. It wasn’t the prettiest cable, but the performance advantage of its polypropylene insulation was dramatic and much appreciated. Several evolutionary steps later, the current version of Type 4 was introduced in 1995—a design whose foundation is so well balanced that it hasn’t changed since then—and still isn’t changing.

Types 9+DBS Low-Distortion & Low-Noise speaker cable is essentially Type 4 with better metal, added layers and techniques of Noise-Dissipation for more effective noise control and AQ's patented Dialectric-Bias System (DBS).

In addition, Type-9+DBS conductors are a little bigger than previous 4-series cables. The conductors are a little farther apart, reducing interaction between adjacent conductors by 35%.

High Purity Conductors - Solid Perfect-Surface Copper+ (PSC+)

Solid Perfect-Surface Copper+ (PSC+) conductors prevent strand interaction, a major source of ear fatiguing transient intermodulation distortion. The astonishingly smooth and pure Perfect-Surface Copper+ eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers. The superior purity of PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor. The astonishingly smooth and pure Perfect-Surface Copper further eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers.

Solid Conductors

Solid Conductors eliminate harshness and confusion due to strand-interaction.

Multi-Layer Carbon-Based Noise-Dissipation

Multi-Layer carbon-based Noise-Dissipation plus Direction-Controlled conductors and shielding significantly lower noise-floor and reduce amplifier Transient-Intermodulation Distortion (TIM).

72V Dielectric-Bias System with CARBON-Level Radio-Frequency Trap (DBS)

All insulation is also a dielectric whose electrical properties affect the integrity of the signal. When the insulation is unbiased, dielectric-involvement (absorption and non-linear release of energy back into the signal flow) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a significant problem for very time-sensitive multi-octave audio. AudioQuest’s multi-patented DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes the nonlinear time delays, resulting in clearer sound emerging from a “blacker” background. The inclusion of an RF Trap (a technology developed for AudioQuest’s Niagara Series of power products) in the DBS battery pack further reduces radio-frequency noise. The DBS battery packs will last for many years. A test button and LED allow for the occasional battery check.

Star-Quad Geometry

Balanced Star-Quad Geometry reduces time-smearing while preserving dynamics, and clarity.


  • Featuring a black & red braid, terminated with SureGrip 1000 connectors
  • 72V Dielectric-Bias System for black backgrounds and reduced noise
  • 100% Solid Perfect-Surface Copper+ for optimized smooth, natural sound
  • Superior Noise-Dissipation using Multiple Carbon Layers plus Direction-Controlled conductors and shielding—significantly lowering the noise floor and reducing Transient Intermodulation Distortion (TIM)

Built on a 39-Year Foundation of AudioQuest 4-Conductor Star-Quad Speaker Cables

C-4, AudioQuest's first Star-Quad design, was introduced in 1980. A couple of years later, the original strange-looking polypropylene-insulated Type 4 was first introduced. Several important evolutionary steps later, the most recent version of Type 4 was introduced in 1995--a design whose fundamentals are so well balanced that it hasn't changed since then--and still isn't changing.

However, since AudioQuest first started using superior-to-OFHC metals in 1985, better metal has always been an option. Models CV-4, GO-4, KE-4, and AG-4 all used the Type 4 design, but with Perfect-Surface metals. These models also featured the added benefit of AudioQuest's Dielectric-Bias System (DBS).

Type 5 is fundamentally Type 4 with better metal. Type 9 ups the game with more PSC+ and added layers and techniques of Noise-Dissipation for more effective noise control than any previous Type 4 iteration. And, Type 9+DBS adds the black background and preservation of natural beauty that AQ's Dielectric-Bias System (DBS) enables.

Also, the new models are a little bigger than previous 4-Series cables, the conductors are a little farther apart, and interaction between adjacent conductors is reduced by 35%.

Applying and now finally naming a technique AudioQuest has used for decades, Type 5 uses a finessed combination of Perfect-Surface Copper+ (PSC+) in Type 5's grainless-sounding Sonic-Signature conductors, plus Long-Grain Copper (LGC) in the larger carry-the-weight conductors.

No, AQ hasn't gone bonkers. We are not claiming different audio frequencies go down different conductors! However, in a manner similar to bypass capacitors in a speaker crossover or in electronics, the smallest conductors in AQ's multi-conductor-size cables set the "information envelope" or Sonic-Signature.The larger conductors, even though compromised above 10kHz due to skin-effect, do the also-important heavy lifting--keeping cable impedance to a minimum.

Types 5, 9, and 9+DBS are full-range cables, but are of course superb when used in a Double-BiWire combination. Very effective Double-BiWire (DBW) options include double Type 5, double Type 9, and the especially cost-effective options of Types 9 or 9+DBS on treble with Types 5 or 9 on bass (the importance of metal and of DBS is proportional to frequency).

Higher up in the AQ range, the Robin Hood models use the same 4 conductors (same size, same metal) as Types 9 and 9+DBS. This means a Robin Hood ZERO cable on treble can be combined with any model of AQ Star-Quad cable on bass (CV-4, GO-4, etc.)--all a very cost-effective step along the way to a Robin Hood Double-BiWire.
