Speaker cables carry the highest currents in the entire setup, they require an adequate wire size to ensure low-loss transmission. The current generates correspondingly strong magnetic fields. In addition, the cable inductance constitutes a frequency-dependent resistance to the (alternating) current. Therefore, speaker cables are required to be low-inductance. Exactly this has been systematically implemented with the LS-1204 Air: A highly sophisticated wire layout – the “fourfold multicore” design – lowers the inductance, thus producing a fully neutral sound over a wide frequency range. Moreover, the design leads to a neutralization of overlapping magnetic fields around the individual conductors. All frequencies are transmitted freely and without any latency, allowing for producing an incredibly open sound with unprecedented detail. At the end of the Air Helix, the four conductors inside the LS-1204 run into so-called aluminum splitters arranging them for the receiving connector. Between the splitter and the connector, in-akustik implements ultra-flexible parts molded from a special elastomer. These parts are fixed inside the splitter using a specifically designed plastic plug, thus ensuring maximum cable flexibility even in the connector region. The molded parts extend to the connector front and enclose the inner connector components, which underlines the plain yet charming appearance of the LS-1204 Air.

Just like all speaker and audio cables from our Reference series, the LS-1204 Air and NF-1204Air are entirely manufactured in Germany. The clips are meticulously assembled by hand at on-site factory in Germany. The resulting Air Helix design then receives a PE network jacket before the finish cable is subjected to a thorough and final inspection. We have opted for Tellurium copper as the conductor base material rather than brass. This is because Tellurium copper offers almost twice the conductivity. Than using custom made machine strips, a complex technique with lacquer coating on the highly pure copper wires of the Cross Link Super Speed waveguide is formed. Afterward the bare wires are crimped with a 1.5-t pressure directly on the connector. This technique prevents the occurrence of contact resistance that often occurs with the use of additional materials such as solder, wire and sleeves. The connector surfaces are rhodium coated because this is an extremely robust material that insures optimum contact.
