High-End Speaker Cables

Because 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.

High-end loudspeakers need power – and a lot of it, quickly and precisely. For the perfect sound the power must correspond one hundred percent with the analog image of the original sound source, be it an A cappella soloist or a stomping rock concert. A few technical tricks that help to skillfully circumvent physical influences are required to deliver this power to the loudspeaker right on time and holistically. Line resistance and line inductance play an important role with speaker cables. The powerful Referenz LS-8005 AIR has impressive 32 Cross Link Super Speed waveguides with an enormous total cross-section of 38 mm². The cross-section alone, however, does not make a good cable. The smart nesting of the conductors almost completely eliminates magnetic fields, paving the way for the finest sound facets and powerful pressure in equal measure. Good sound needs air! In developing our Air technology, we have proven that an audio cable’s insulation plays a key role and has a significant influence on the sound. This is due to dielectric losses and the electrostatic properties of the insulating materials, which burden the hi-fi system like heavy luggage and make it sluggish. By “omitting” this strain we then help the entire hi-fi chain to achieve top performance. We do this with special clips that guide the signal conductors through the cable in a row and freely suspended. Grounding option: The number of cell phones, WiFi routers, Bluetooth devices, PV systems and charging stations etc., is constantly increasing. This also increases the potential for electromagnetic interferences, which can affect hi-fi and high-end systems. Cables act like antennae and can transfer the interferences to the devices, where they overlay the audio signal in sensitive circuit areas, resulting in a “washed out” sound. Effective shielding and grounding concepts are crucial to protect the sound. The grounding cable of a record player is a very well-known example of this. The LS- 8005 AIR is equipped with a grounding option, which, depending on the configuration, can be connected to the amplifier’s earth, the protective conductor or earth or a grounding box, to divert disturbances.

Experts have already been impressed by the LS-1204 AIR (copper). This is how AUDIO summed it up: "A stroke of genius that shows competitors how it should be done – in terms of sound, too. This was wonderfully dynamic, with the most fabulous drive reaching the speaker cones. Admittedly, the price is not low, but the acoustic yield is truly world class. What's more, everything was made by hand. You can feel the love for the product." With the LS-1205 AIR Pure Silver, the currently most filigree model in AIR technology is now also available as a pure silver cable. The structure, dimensions and conductor arrangement of this cable correspond to the copper version of the LS-1205 AIR. As with the LS-4005 AIR Pure Silver and LS-2405 AIR Pure Silver, the conductors have been optimized. Pure silver is used as the conductor material for the LS-1205 AIR Pure Silver too. Under realistic conditions, silver is currently the most conductive material. At 61.35 S/m (Siemens pro Meter), its conductivity is approximately six percent superior to that of copper. The electrons move 1.5 times faster than in a copper conductor! Click here and discover the exciting details

AIR technology is a milestone in our more than 46-year company history and is causing a sensation in the hi-fi industry worldwide. The approach itself sounds relatively banal: The physically induced losses must be minimized in order to transmit the original music signal as authentically and neutrally as possible. And, thanks to the AIR technology, loss-free transmission is closer than ever before. It leads to a significantly better reproduction, which is not only subjectively audible, but also objectively measurable. The insulation (or dielectric) of the AIR cables is practically perfect thanks to the air insulation, and hardly affects the sound at all. The structure, dimensions and arrangement of the conductors are optimized, and approach the limits of what is physically possible. Adding another highlight to this perfect audiophile foundation, we then focused on the conductor material of the cables. Copper in the appropriate purity is already a very good conductor. A superconductor, where electrical resistance is zero, would be perfect, of course. Unfortunately, superconducting materials require temperatures of at least -70 degrees. Under realistic operating conditions, the best conducting material we have is currently silver. At 61.35 S/m (Siemens pro Meter), its conductivity is approximately six percent superior to that of copper. However, this precious metal is about 100 times more expensive.

We do this with special clips that guide the signal conductors through the cable in a row and freely suspended. To get closer to the pinnacle of audiophile perfection, we also carefully examined the conductor material. Copper in the right purity is itself already an excellent conductor, but a superconductor with no ohmic resistance to the current would be simply perfect. The material’s superconducting properties, however, require extremely low temperatures of at least -70 degrees. Under realistic conditions, silver is currently the most conductive material. With a conductivity of 61.35 S/m (siemens per meter), it outperforms copper by around six percent. Many manufacturers only use silver-plated conductors, which over time can seem, “bright”, “metallic” and even, “annoying”. We, on the other hand, use pure silver, which has a far more neutral sound. Due to the higher drift speed of the electrons, our pure silver cable delivers a more penetrating and sumptuous sound performance, across all frequency ranges. On the other hand of course, silver is about one hundred times more expensive than copper.

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 details

Like the flagship model, the LS-204 is also based on Micro Air technology. The difference lies in the multicore architecture. Compared to the XL version, the LS-204 has four instead of six Concentric Copper conductors. This cable boasts an agile character and was primarily developed for slim floorstanding speakers with smaller bass drivers. The Referenz LS-204 Micro AIR is available as a single-wire version with BFA bananas or spade lugs, or as an Easy Plug version. Click here and discover the exciting details

The LS-104 is an excellent entry-level model to the Micro AIR series. It already stands out clearly from standard cables and demonstrates the acoustic potential of this technology. Sensitive amplifiers in particular harmonize excellently with this cable. The Referenz LS-104 Micro AIR provides an open and relaxed sound. It is also available with BFA bananas or spade lugs and as an Easy Plug version. Click here and discover the exciting details

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 Referenz LS-603 with its 6-fold multicore design has remarkable electrical and acoustic characteristics. The large, effectively usable cable cross-section ensures excellent and controlled bass reproduction and a high level of efficiency. The in-akustik DUO PE II insulation uses foamed polyethylene to reduce the capacitance load on cables. This serves to give music reproduction greater brilliance and spatiality. In addition, a layer of solid PE protects the foamed PE from mechanical stress and the multicore design minimizes any inductance which can impede the signal current. This results in a more precise and powerful sound reproduction. The high-speed waveguide uses a polyethylene core to minimize the skin effect. This means that the effectively usable cross-section remains the same for all audio frequencies. The result is a balanced, broad sound spectrum that enriches your listening pleasure.

The Referenz LS-1102 has 6 conductors, each with 37 concentrically stranded wires. The cores are in triple symmetry and have been specifically arranged in the CC-187 design to keep the inductance low and the resistance linear. The larger cable cross-section ensures excellent and controlled bass reproduction and high efficiency. Polyethylene (PE) already boasts excellent electrical properties for audio, video and digital cables. The foaming process generates an air content in this dielectric, which further diminishes any annoying battery-like cable capacitance. The reproduction gains even greater brilliance and spatiality. A layer of solid PE protects the foamed PE from mechanical influences. Inductance is a critical behavioral feature of a cable, causing resistance to the signal flow, rising with the frequency. Multicore architectures, such as that of the LS-1102, reduce this effect and bring more precision and punch to the sound. With conventionally stranded wires, the individual strands run chaotically through the conductor. This leads to undefined contact points, which can result in degraded signal transmission. In contrast to this, each wire in the Concentric Copper structures has a precisely defined position within the conductor. This enables homogeneous signal transmission and ensures crystal-clear audio reproduction.

The Referenz LS-1002 has 4 conductors, each with 37 concentrically stranded wires. The cores are arranged in a double symmetrical fashion and specifically configured in the CC-297 design to keep the inductance low and the resistance linear. The larger cable cross-section ensures excellent and controlled bass reproduction and a high level of efficiency.
