The Audioquest Rocket 22 cable is designed to connect an amplifier to speakers. It is sold by the meter to suit different setups. Its construction includes a specific metal assembly and a defined internal geometry to preserve the audio signal. This cable is CL3/FT4 certified, allowing its use in traditional or in-wall hi-fi installations.
A metallurgical construction where each copper plays its part
The Rocket 22 employs a conductor architecture based on a calculated balance between two types of copper with complementary properties. Long-Grain Copper (LGC), which makes up 37% of the conductors, features an optimized crystalline structure where the copper grains extend over greater lengths. This configuration minimizes internal junctions, those transition zones between grains that typically generate micro-distortions as the electrical signal passes. LGC is concentrated in the central part of the conductor bundle, forming the stable core of transmission.
The outer layer of the conductor uses Perfect-Surface Copper (PSC), representing 63% of the composition. This material benefits from a surface treatment that virtually eliminates microscopic roughness. This molecularly polished surface plays a decisive role in high-frequency transmission, where the skin effect naturally concentrates electrical current at the conductor’s periphery. PSC thus ensures a smoother, more natural rendering of treble, without harshness or artificial coloration.
The layout of these conductors follows Audioquest’s patented True-Concentric principle. Unlike conventional cables where strands run in parallel or randomly, the Rocket 22 organizes its conductors in successive concentric layers, each layer spiraled in the opposite direction to the previous one. This alternating spiral direction eliminates linear contact lines between layers and increases pressure at point contacts. This semi-solid geometry keeps the spatial relationships between strands fixed along the entire length of the cable, drastically reducing parasitic electromagnetic interactions between conductors.
A double-helix geometry to tame inductance
The Rocket 22 adopts a twisted double-pair geometry that radically transforms its electrical behavior. Each channel of the cable includes four conductors arranged in two pairs, each pair twisted around itself. This configuration contrasts with parallel-conductor cables, which have naturally high inductance, a source of temporal smearing of the signal and a confused rendering of transients.
Twisting the conductors creates a mutual cancellation effect of the magnetic fields generated by current flow. This reduction in inductance translates acoustically into a more linear extension of bandwidth, with tighter, more defined bass and airier, more natural highs. The total cross-section of 3.31 mm² per channel offers sufficiently low electrical resistance to preserve the signal’s dynamics and authority, even over long distances.
The PVC jacket with blue stripes does more than just visually identify the cable. This outer sheath protects the assembly against mechanical stress while minimizing the absorption of electromagnetic energy. The PVC dielectric was selected for its stable long-term insulation properties, avoiding progressive polarization phenomena that can degrade cable performance after several years of use.
Installation versatility and multiple configurations
The Rocket 22 stands out for its ability to adapt to various installation configurations without requiring complex preparation. In standard single-wiring configuration, the two red conductors are grouped to form the positive pole, while the other two conductors form the negative pole. This straightforward implementation allows quick installation while fully benefiting from the cable’s construction technologies.
For speakers equipped with dual binding posts, bi-wiring is possible without modifying the cable. At the amplifier end, the conductors remain grouped by color. On the speaker side, one red conductor feeds the positive high-frequency section, one black the negative high-frequency, the second red goes to the positive low-frequency, and the second black to the negative low-frequency. This physical separation of electrical paths for different frequency ranges eliminates inter-band modulation caused by strong low-frequency currents on the more delicate treble signal.
CL3/FT4 certification authorizes the installation of the Rocket 22 in walls and conduits, in compliance with North American and European fire safety standards. This approval attests to the sheath’s fire resistance and its low emission of toxic fumes in the event of combustion. Professional installers particularly appreciate this feature, which simplifies integration into custom installation projects or built-in home theater systems.
An acoustic positioning between neutrality and musicality
In listening, the Rocket 22 requires a break-in period of about a week to fully reveal its qualities. The first hours may exhibit a slightly veiled and thick character that gradually fades. Once stabilized, the cable delivers a balanced sonic signature that favors coherence and fluidity rather than a spectacular emphasis on certain frequency ranges.
Compared to the Rocket 11, the bass gains in definition and articulation, with better differentiation of bass lines and a more natural extension into the sub-bass. The midrange retains a fleshy density that gives substance to voices and acoustic instruments, without tipping into excessive coloration. The highs particularly benefit from the outer PSC, with a more refined rendering of harmonics and better resolution of ambient micro-details.
The soundstage expands noticeably, with better lateral separation of sources and increased depth of the stereophonic image. Layers of sound stand out more clearly, creating a more convincing three-dimensional sense of space. This enhanced spatialization does not come at the expense of central focus, which remains precise and stable even in complex orchestral passages.
