The unique AIR technology impressively demonstrates what high-end cables can achieve in terms of sound. For entry into this class, the sophisticated AIR technology is now available for the first time in a flat "ribbon" design for self-assembly. The Reference LS-804 AIR speaker cable has four wires running flat next to each other. The wires in this model are also held in position by specially developed clips and cross-connected at both ends of the speaker cable. In this way, the electrical parameters of capacitance and inductance are finely tuned to each other. The division into several smaller, separate conductors also reduces the skin effect. This is supported by the specially developed Cross Link Super Speed waveguide. In conjunction with the Air technology, i.e. the "omission" of insulation material, which would "soak up" some of the energy like a sponge, the Reference LS-804 AIR is able to follow very fast impulses. The sophisticated details counteract unwanted electrical effects and make this cable an exceptional loudspeaker connection.

The LS-404 Micro AIR is a further installment in the success story of the Micro AIR technology: As with the already legendary AIR Helix cables, air is also a central component of the insulation concept in the Referenz Micro AIR technology. Due to the low speaker impedances, however, low line resistances and a low inductance are also very important for speaker cables. For this reason, the Referenz LS-404 Micro AIR uses a total of 8 concentric copper conductors in addition to the air dielectric. Thanks to this multicore architecture, the magnetic fields of the positive and negative conductors overlap and neutralize each other. This significantly reduces the inductance of the cable, which guarantees unaltered transmission of the audio signal over a broad frequency spectrum. Due to our approach, the LS-404 has an extremely balanced sound character with precise timing, on top of a solidly controlled foundation. This cable is primarily designed for full-size floorstanding loudspeakers. The impression sound makes on the listener is always subjective, of course, and depends in no small part on the overall constellation of a hi-fi system. In the end, the decisive factor is your own personal listening impression.
Click here and discover the exciting detailsBecause the speaker cable carries the largest current in the entire device chain, a suitable conductor cross-section is required to transport it with as little loss as possible. This current generates correspondingly strong magnetic fields and, since it is alternating current, there is a frequency-dependent resistance in the inductance of the cable.
Low inductance is therefore particularly important for speaker cables - and this is precisely what has been achieved with the LS-1205 Air: The cable's inductance value has been reduced by a particularly ingenious arrangement of the conductors, the 4-fold "multicore" structure, enabling it to behave in a completely sound-neutral way over a wide frequency range. In addition, the magnetic fields generated around the individual conductors overlap and neutralize each other. This means that all frequencies are transported unhindered and without any time delay, enabling a fabulously open and detailed musical presentation. At the end of the air helix, the LS-1205 Air’s four conductors are separated into so-called aluminum splitters for the receiving connector.
In the area between the splitters and plug, in-akustik uses highly flexible molded parts made of a special elastomer. These parts are fixed inside the splitter using a specifically designed plastic plug. This means that the cable remains reliably flexible in the connection area as well. The molded parts run right to the front of the connectors and enclose their inner workings - which underscores the sleek yet attractive design of the LS-1205 Air.

AIR-Ribbon technology
With the so-called air ribbon cable, four wires run flat and not helically next to each other as with the LS-1205, 2405 and 4005 AIR air helix cables. The cores of the LS-804 AIR are also held in position by specially developed clips and cross-connected at both ends of the speaker cable. In this way, the electrical parameters of capacitance and inductance are finely tuned to each other. The division into several smaller, separate conductors also reduces the skin effect. This means that the entire conductor cross-section remains usable even at high transmission frequencies. In conjunction with the Air technology, i.e. the "omission" of insulation material, which would "soak up" part of the energy like a sponge, the Reference LS-804 AIR is already able to follow very fast impulses. The sophisticated details of the Air technology counteract unwanted electrical effects and make it an exceptional loudspeaker cable. The LS-804 AIR harmonizes particularly well with less monumental amplifiers and ensures relaxed music enjoyment.
Electrostatics and capacity
Everyone knows this effect when you take off a sweater with a high synthetic content and it crackles and sparks. The reason for this is that the incorporated synthetic material stores electrical charge, which discharges again. The same thing happens in the dielectric, the insulating material of a cable. It "soaks up" electrical energy like a sponge and then releases it again later. In the case of an audio cable, however, this is part of the audio signal. One measure of this is the cable capacitance, i.e. the unwanted storage capacity of the cable. While capacitors should store energy and have a correspondingly high capacitance, the capacitance of the cable should be as low as possible. It significantly influences the transmission properties due to losses and also leads to interactions with the connected electronics. Air insulation, as realized with Air technology, is therefore ideal as it reduces the capacitance to a minimum.
Cross Link Super Speed waveguide
The conductor material also plays a major role. As with the Air Helix models, the Reference LS-804 AIR consists of high-purity copper wires braided onto a PE core. A wafer-thin layer of lacquer on the wires prevents eddy currents within this conductor and also protects the copper from oxidation. Another sound-relevant advantage is the bifilar structure of the conductors, which is also used in Air-Ribbon technology. It ensures that the magnetic fields generated by the current are partially compensated. This proven design ensures that the conductor behaves neutrally over a particularly wide frequency spectrum.
