Cardas HP Crosslink (2 x 2.5m)
Overview
The Crosslink by Cardas Audio is a speaker cable that has been on the market for about 25 years. Designed in the United States, it uses principles derived from telecommunications engineering and a geometry based on the golden ratio. Intended for entry- to mid-range stereo and home theater systems, it offers easy installation and a balanced audio presentation.
An assembly designed around the golden ratio
The Crosslink Speaker Cable is built on a four-conductor configuration of 14.5 AWG Grade 2 OFHC copper. Each of these conductors comprises 28 strands of pure copper, for a total of 108 strands in the complete cable. This multiplication of fine strands optimizes signal transfer across the entire audio spectrum, from bass to treble.
The distinctive feature of the Crosslink lies in the application of the golden ratio (1.618…) to the arrangement of its conductors. This mathematical proportion, found in spiral shells and grand concert halls, is used here to control the cable’s internal resonances. The finest strands occupy the center, while the cross-sections increase progressively toward the periphery following a precise geometric progression. This layout aims to prevent the different strands from entering common resonance, a phenomenon that can color the sound.
The so-called “Star-Quad” structure arranges the four conductors concentrically. Between them, natural cotton threads provide mechanical damping without memory effect. The insulation uses an EEA (ethylene acrylic acid) dielectric and cotton, chosen for their favorable electrical properties. Everything is protected by a supple PVC outer jacket 9.27 mm in diameter, giving the cable good flexibility despite its generous gauge.
Position within the Cardas range
The Crosslink occupies the second rung of the Cardas hierarchy, just above the 101 Speaker. Above it are the Iridium and Parsec ranges, then the Clear cables (Sky, Cygnus, Reflection, Clear, and Clear Beyond). This entry-level position is not misleading: unlike the higher models that employ Cardas’s ultra-pure Grade 1 copper, the Crosslink uses Grade 2 copper while benefiting from the same golden ratio-based design philosophy.
Cardas’s entry-level cables are specifically designed to accommodate the typical shortcomings of the systems they target. Many multichannel setups or mid-range components tend to accentuate high frequencies or present a certain aggressiveness. The Crosslink provides a natural counterbalance to these traits. Conversely, Cardas Clear cables reveal—without compromise—the strengths and weaknesses of the high-end systems they are intended for.
Versatility of use and installation
The presence of four distinct conductors makes the Crosslink particularly adaptable. For a conventional connection, the conductor pairs are twisted together, creating a cable equivalent to 10 AWG. For speakers equipped with dual binding posts, the four conductors can be split between the bass and treble terminals, enabling bi-wiring without multiplying cable runs.
Bare copper greatly simplifies preparation. No solder pot is required: simply strip the end, twist the strands, and insert them into five-way or spring-loaded binding posts. This simplicity appeals both to busy professionals and enthusiasts who want to finish their own cables. Moreover, Cardas offers the Crosslink in two versions: either factory-terminated with connectors or by the meter for custom installations.
CL2 certification authorizes in-wall runs without violating building codes. This is why the Crosslink is found in many custom home installations, where cables are routed discreetly between rooms. It is also used in professional contexts: sound reinforcement systems, concert installs, and even high-level car audio competitions.
The factory connectors reflect the care taken by Cardas. The GRS spades and CABE bananas are machined from solid copper, then silver-plated with a final touch of rhodium. This treatment ensures optimal conductivity while preventing oxidation. The cold crimping, performed by hand in Bandon, preserves the integrity of the copper by avoiding any thermal alteration. A flexible protective sleeve covers the junction between the cable and the connectors.
Sonic signature and electrical behavior
Electrical measurements of the Crosslink reveal a capacitance of 168 pF/m and an inductance of 0.54 µH/m. These moderate values allow the cable to match a wide variety of amplifiers and speakers without risking problematic electrical interaction. The Q factor of 10.6 indicates stable behavior in the face of impedance variations.
The Crosslink’s sound is characterized by overall balance without particular emphasis. The midrange retains a certain density and natural rendering, especially pleasing on vocals. The treble remains smooth, without the sometimes excessive brightness that can be generated by certain digital systems or metal-dome tweeters. The bass has body and definition, with a solidity that is sometimes lacking in cables in this category.
This balanced approach makes the Crosslink a sensible choice for calming slightly aggressive or analytical systems. It does not add pronounced coloration but brings a certain roundness that favors long listening sessions. The soundstage unfolds naturally, with good separation of layers without creating an exaggerated sense of depth. Subtle details emerge without being pushed forward: a double bass pluck reveals both the string attack and the body resonance of the instrument.

Frequently Asked Questions
Can the Crosslink work with high-power speakers?
With its total cross-section of 10 AWG (about 5 mm²), the Crosslink is suitable for most home installations up to around one hundred watts per channel. Beyond that, or for speakers with very low impedance (less than 4 ohms), it’s better to consider a larger gauge cable or to double the runs to increase current-carrying capacity.
What’s the difference between the Crosslink’s Grade 2 copper and the Grade 1 used in higher models?
Cardas’s ultra-pure Grade 1 copper has a purity of 99.9999% versus 99.99% for Grade 2. This difference results in slightly higher conductivity and an even more homogeneous crystalline structure. Cardas produces its own Grade 1 copper using a proprietary process, while Grade 2 comes from specialized high-quality OFHC suppliers.
How long does it take for the cable to reach optimal performance?
Like many cables, the Crosslink requires a break-in period during which the dielectrics stabilize. The first hours of listening may seem slightly dry or lacking cohesion. After a few dozen hours of use, the sound becomes more natural and fluid. George Cardas also notes that after moving or reconnecting a cable, you should give it a few hours to settle back into its best form.
Is the Crosslink compatible with other cables in the same system?
Cardas designs its cables to work harmoniously with each other as well as with those from other manufacturers. You can absolutely use a Crosslink for the speakers while employing interconnects from another brand or from a higher Cardas range. What matters most is the overall system coherence and the listening result.
Is the Crosslink suitable for bi-amped installations?
In a bi-amped configuration where each speaker section receives its own amplifier, the Crosslink can certainly be used. Its four-conductor structure lends itself naturally to this setup. To maximize the benefits of bi-amping, you can even consider using two complete Crosslink cables, thereby creating total separation between the bass and treble sections, similar to “shotgun” bi-wiring.
