Inakustik LS-404 Micro Air Speaker Cables

The Inakustik LS-404 Micro Air Speaker Cables are designed for demanding audio systems where precision, balance, and control are essential. Positioned within the Referenz range, these cables build on the success of in-akustik’s advanced Micro AIR concept and are intended for full-size floorstanding loudspeakers and high-performance amplification.

Their engineering focuses on preserving the integrity of the music signal while reducing the unwanted electrical effects that can limit performance. With an extremely balanced sonic character, precise timing, and a solid, controlled foundation, the LS-404 is built to let a system perform at its full potential.

Rather than adding coloration, it aims to pass the signal as cleanly and naturally as possible, making it an ideal choice for listeners who value transparency and musical coherence.

Micro AIR Technology with Air as the Ideal Insulator

A defining feature of the Inakustik LS-404 Micro Air Speaker Cables is the use of Micro AIR technology, where air forms a central part of the cable’s insulation concept. In audio cables, capacitance is an unavoidable physical effect that can store electrical energy and release it with a delay, negatively affecting signal accuracy.

Because air has extremely favourable dielectric properties, it is the ideal material for reducing this problem. To make this possible, in-akustik uses a sophisticated internal structure with tiny diamond-shaped chambers that increase the air content surrounding the conductors.

This enlarges the distance between them and significantly reduces troublesome capacitance. The result is improved transmission behaviour, helping delicate audio signals travel with greater speed, lower distortion, and better overall precision.

Eight-Fold Multicore Architecture for Low Inductance

The LS-404 uses an advanced 8-fold multicore architecture with a total of eight concentric copper conductors. This design is not only about lowering resistance, but also about reducing inductance, which is especially important in loudspeaker cables connected to low-impedance speakers.

By arranging the positive and negative conductors so their magnetic fields overlap and largely neutralise one another, the cable significantly lowers inductive effects that can otherwise influence signal transmission across the frequency range. This helps preserve the original character of the music, maintaining timing accuracy and tonal consistency.

The result is a cable with excellent control, a stable and balanced presentation, and the ability to support a wide spectrum of music with authority, clarity, and natural flow.

Concentric OFC Copper for Accurate Signal Transmission

The conductor system in the Inakustik LS-404 Micro Air Speaker Cables is based on high-purity oxygen-free copper arranged in a carefully controlled concentric structure. Unlike conventional cable designs, where conductor strands can be distributed in a more chaotic way, this multi-layer pattern reduces irregular contact points and minimises runtime differences in the signal path.

That means impulses can be reproduced more accurately, preserving transient precision and maintaining the spatial information contained in the recording. A thin polyethylene layer protects the high-purity copper from oxygen and oxidation, ensuring long-term stability and consistent performance. Because copper remains one of the best practical conductor materials available, the use of OFC copper in this highly organised architecture plays a major role in the cable’s clean, articulate, and controlled sound.

Designed for Neutrality, Not Colouration

Inakustik’s design philosophy is based on the idea that cables should not create a sound of their own. Instead, they should behave as discreetly as possible, avoiding tonal colouration and minimising interactions with connected components. The LS-404 follows this principle throughout its design.

Through its low-capacitance air dielectric, low-inductance multicore layout, and carefully selected materials, it reduces the filter effects that can alter the original signal. The aim is not to impress with an artificial character at first listen, but to provide a more faithful and less intrusive connection that supports long-term musical enjoyment.

This results in a presentation that feels open, natural, and refined, allowing the recording and the quality of the equipment around it to take centre stage.

German Manufacturing with Precision and Care

The Inakustik LS-404 Micro Air Speaker Cables are manufactured in Germany in the company’s own facility, where advanced production processes are combined with detailed manual assembly and rigorous quality control. Every cable is tested after production, both mechanically and electrically, to ensure consistent performance and long-term reliability.

During product development, in-akustik also evaluates live musical performance, reflecting its commitment to combining technical excellence with real-world listening results. The LS-404 is available in a range of lengths and with high-quality terminations, including banana plugs, cable lugs, and Easy Plug connectors.

With its substantial 16 mm diameter, premium materials, and carefully executed build quality, the LS-404 is a serious high-end speaker cable designed to deliver precision, durability, and uncompromised musical performance.
