Iridium Speaker twists two 11.5 AWG Cardas Litz conductors with natural cotton filler, bound in PTFE tape under an ultra-soft TPR jacket. It is hand soldered to Cardas CGMS spades or CABE bananas in Bandon.
Cardas says it suits virtually any amplifier and speaker combination, in long or short runs, and performs like a product costing much more. Jumpers are required for bi-wire speakers.
Key technologies
Ultra Pure Cardas Copper. Grade 1, 99.9999% pure oxygen-free copper, drawn and annealed slowly through silver dies, then given a single poly-nylon coat to prevent oxidation and crosstalk between strands.
Golden Ratio scaled Litz conductors. Multi-stranded conductors in which each layer of strands steps up in size by 1:1.618 from the centre outward, a Cardas patent that controls strand resonance.
Quad Eutectic solder. Hand soldered with Cardas Quad Eutectic solder and Cardas rosin flux at 800 °F irons, by the Cardas terminators in Bandon.
Made in Bandon, Oregon. Every Cardas cable is built and hand terminated at the Cardas factory on the southern Oregon coast, and carries a transferable lifetime warranty.
Choosing length and terminations
Measure along the path the cable will actually take — down the rack, along the floor, up to the speaker terminals — and round up. Cardas charges by the half metre.
Both cables in the pair are the same length. Keeping left and right equal is the normal practice, even if one speaker is closer.
Spades suit binding posts you can torque down; bananas are quicker and fit most posts. You can mix: for example, spades at the amplifier and bananas at the speakers.
This cable is not built as an internal bi-wire; for speakers with separate bass and treble terminals, add a set of Cardas jumpers.
