LS-1205 AIR
High-end speaker cable Quality: Referenz AIR Helix Point-to-Point | Multicore
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.

LS-8005 AIR
High-end speaker cable Quality: Referenz AIR Helix Point-to-Point | Multicore
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.

LS-1205 AIR Pure Silver
High-end speaker cable Quality: Referenz AIR Helix Point-to-Point | Multicore | Pure Silver
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

LS-2405 AIR Pure Silver
High-end speaker cable Quality: Referenz AIR Helix Point-to-Point | Multicore | Pure Silver
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.

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.

LS-404 Micro AIR
Referenz Micro AIR Quality: Referenz Air dielectric
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.

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 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.

Buying the right speaker cable

Choosing the right speaker cable can significantly impact the sound quality of your HiFi system. In addition to the conductor cross-section, the cable's inductance, or the construction of the cable, and other factors also play a role.

Conductor cross-section

The conductor cross-section should be large enough so that the current flowing through the cable can be transported with as little loss as possible. The higher the power of the amplifier and the longer the cable run, the larger the conductor cross-section should be.

Rule of thumb:

Standard: between 2.5 mm² to 4mm² for normal HiFi systems with cable lengths up to 5 meters.

Better Sound: 4 mm² or more for longer cables, powerful amplifiers, or an even better audiophile sound experience.

High-End: In audiophile music reproduction, special requirements are placed on signal transmission. Besides the cross-section, especially the cable architecture or the construction of the cable plays a crucial role.

What matters:

Higher Power: High-end speakers often need to be supplied with significantly more power than ordinary HiFi speakers.

Longer Cable Routes: In event technology, studios, or home cinema, cable routes of 10 meters or more are not uncommon.

Loss-Free Signal Transmission: To minimize sound losses and distortions, among other things, a thicker cross-section is necessary.

High-Quality Music Reproduction: Cross-sections up to 10 mm² for high power, long cable routes, and loss-free signal transmission.

Expanded Sound Spectrum: Thicker cables can transmit a wider frequency spectrum, revealing more details and nuances in the sound.

Dynamics and Precision: Improved dynamics and precision in the bass range as well as a clearer and finer resolution in the high-frequency range.

Future-Proof: A higher cross-section provides reserves for future upgrades of your HiFi system.

Cable inductance

The cable's inductance acts like a frequency-dependent resistance, which can dampen the high-frequency range. Therefore, a cable with low inductance is advantageous. This is achieved by a special construction of the cable, for example, through a multicore structure. The clever arrangement of conductors in the multi-layered multicore structures creates overlapping areas of magnetic fields that significantly reduce inductance. The entire frequency spectrum, including high tone frequencies and dynamic pulse sequences, are transmitted unhindered and without time delay. Music sounds more detailed. The sound is more dynamic. All details are worked out precisely and harmonically.

The construction of our audiophile AIR speaker cables is based on the multicore principle and thus reduces inductance.

Cable capacity

Particularly problematic for as loss-free signal transmission as possible is the capacity, since every cable has an electrical capacity. This behaves similarly to a battery that must be continuously charged and discharged by the components in the cable. These processes burden the audio signal, cause phase shifts, and influence the sound quality of the system. The capacity is influenced by various factors, such as the material with which the conductors are insulated (usually PVC, known as dielectric) and the distance between the conductors. Depending on which insulating material is used and how far the conductors are from each other, the capacity of the cable varies.

The AIR-Helix construction of our high-end speaker cables allows for the use of air as a dielectric (besides vacuum, the best possible dielectric) to keep the conductors at a consistent distance from each other throughout the entire length of the cable.

Experiment: Here you can learn how insulation and conductor distance affect capacity.

In summary

  • The construction of the cable: The multicore construction reduces inductance.
  • The insulation of the cable: Air as insulation (dielectric) minimizes the capacity
  • The quality of the connectors: The connectors should be coated with very hard materials (e.g., Rhodium) to prevent corrosion.
  • The material of the conductor: Copper is the most commonly used conductor material and achieves excellent sound properties depending on the degree of purity. Pure silver conductor is the best but also by far the most expensive conductor material. Not to be confused with silver-plated conductors, which tend to emphasize the high-frequency range!

Are losses on speaker cables measurable?

To get to the bottom of this question, we take you to our lab in an exciting webinar. In this webinar, we analyze the results of a measurement setup and consider what relationship might exist between sound and cable. In addition to the actual measurements, we also show you a very astonishing experiment.

Buying high-quality speaker cables

Many HiFi enthusiasts wonder whether it's worth investing in high-quality speaker cables. The answer is not simple, as it depends on various factors. In addition to optimizing room acoustics, the correct placement of speakers, and the finely tuned selection of electronics, the appropriate cabling of your HiFi chain also holds significant potential.

Basically:

The higher the quality of the cable, the lower the losses. This means that more of the amplifier's signal reaches the speaker, making the music sound more detailed and powerful.

First-rate cables can also improve the spatiality of the sound image. The individual instruments and voices are more locatable, and the overall sound impression appears more natural.

High-Quality Accessories for Speaker Cables

In addition to the speaker cables themselves, there are several useful accessories that can facilitate installation and use and can improve sound quality.

Here are some examples:

Banana plugs:

Banana plugs allow for a quick and easy connection between the speaker cable and speaker.
They are available in various designs, e.g., as straight or angled plugs.
For high-end systems, we recommend rhodium-coated plugs to prevent corrosion and contact resistance.

Spade connectors:

Spade connectors are also available in various designs. Our high-end versions are rhodium-coated and feature a slotted contact fork. The contact spring created by the slot deforms concavely when tightened, thus preventing the spade connectors from slipping out.

Cable bases:

The cable bases consistently keep the cable at a distance from the ground. This reduces unwanted capacities and relieves the electronics.
