The new Reference LS-2404 AIR loudspeaker cable combines the outstanding qualities of its predecessor – the LS-2404 – and the almost legendary NF-2404 audio cable. This has resulted in a loudspeaker cable that not only has the all-important low inductivity necessary for its application, but also low capacity values and low dielectrical losses. Interdependencies have been reduced and the amplifier can function in a more detached manner. Even if this may seem paradoxical: Thanks to the innovative air insulation, high fidelity becomes a simply breath-taking sound experience with this cable.

Air Helix Structure

The air-helix construction is wholly unique. We have developed a special clip to ensure air insulation that is as close to perfection as possible. A large number of these clips form the supporting structure on the inside of the cable. This holds the signal conductor free in the air in a helix form and guides it through the cable at defined intervals. The flexibility of this construction is attained with two bridges that hold the clips together evenly and at exact intervals. The Cross Link Super Speed waveguides are threaded and fitted with clips by hand with extreme care in our own manufacturing unit. Afterwards the air-helix created in this manner is given its PE network jacket – again by hand. Finally the rhodium-coated plugs are fitted and the cable function is tested.

Cross Link Super Speed Waveguides The conductors themselves of course also play a major role. The LS-2404 is made of 24 highly pure copper wires braided on a PE core. An exceedingly thin coating layer on the wires prevents eddy currents inside this Cross Link Super-Speed Waveguide – the rigorous further development of the super-speed waveguide. This conductor is also used in the NF-2404, but it is considerably more effective in the LS-2404 AIR. The reason for this is that by far the largest currents in the entire audio chain flow through the loudspeaker cables. Part of the correspondingly strong magnetic fields are already compensated by the eight wires on their own. This is ensured by the braided and therefore opposed stranding of the individual wires. Their wafer-thin lacquer coating insulates the wires from each other. The structure ensures greater stability and “peace” in the conductor.

Double Layer Multicore The finding that the loudspeaker cable should primarily have a low inductivity has been optimally implemented in the LS-2404 AIR: The two-layer arrangement of the double-layer multicore allows the conductors to overlap and neutralise the magnetic fields that arise around the individual conductors. This considerably reduces the inductivity of the cable and also allows the high sound frequencies to be transferred without hindrance or time delays.

PE-Network Jaket Every additional type of material used (such as PVC insulation) impairs the electrical characteristics of a cable. Therefore the Reference cables are braided with the PE network jacket using a sophisticated technique. This means the cables consist of only two materials: copper and polyethylene.

Hand made by in-akustik

Just like all speaker and audio cables from the Referenz series, the LS-2404 AIR is entirely made in Germany. The clips are meticulously assembled by hand at the on-site factory and then threaded into the Cross Link Super Speed waveguide. The resulting Air Helix then receives a PE network jacket and rhodium-plated plugs before the finished cable is subject to thorough final inspection.
