Inakustik LS-404 Micro Air Bi-Wire Speaker Cables

The Inakustik LS-404 Micro Air Speaker Cables in bi-wire configuration are designed for serious Hi-Fi systems where control, transparency, and timing are critical. Created for full-size floorstanding loudspeakers, this cable combines advanced conductor geometry with a highly developed insulation concept to preserve the integrity of the audio signal across the full frequency range.

In a bi-wire setup, the cable provides separate paths for high and low frequency sections, helping to reduce interaction between bass and treble signals at the speaker terminals. This can improve clarity, enhance separation, and deliver a more open and controlled presentation.

The LS-404 is engineered to provide an extremely balanced sound character, with precise timing, strong tonal coherence, and a firm, controlled foundation that supports both musical detail and dynamic impact.

Micro AIR Technology and the Benefits of Air Dielectric

At the heart of the Inakustik LS-404 Micro Air Speaker Cables is the brand’s sophisticated Micro AIR technology, which uses air as a central part of the dielectric structure. Every cable is subject to parasitic effects, and one of the most important is capacitance, which allows the insulation material to store and release energy with a time delay.

In audio transmission, this is undesirable because it can affect signal purity and timing. Air is an ideal insulator because it contributes virtually no such effect. To maximise this benefit, the LS-404 uses a complex diamond-shaped internal structure that creates numerous tiny air chambers. This increases the air content surrounding the conductors, reduces troublesome capacitance, and helps optimise transmission characteristics for sensitive music signals.

Eight-Fold Multicore Design for Bi-Wire Control and Stability

The LS-404 is distinguished by its 8-fold multicore architecture, which is especially valuable in a bi-wire configuration. This design uses eight concentric copper conductors to achieve very low line resistance and reduced inductance, both of which are essential when driving modern loudspeakers with low impedance characteristics.

In the cable, the magnetic fields of the positive and negative conductors overlap and largely neutralise one another, significantly lowering inductive influence. In a bi-wire arrangement, this contributes to improved stability and cleaner separation between frequency ranges, helping bass remain tight and controlled while treble stays open and detailed.

The result is a cable that sounds highly composed and balanced, maintaining signal accuracy over a broad frequency spectrum and supporting a presentation that feels rhythmically precise and tonally complete.

High-Purity Concentric Copper for Precise Signal Flow

The conductors used in the Inakustik LS-404 Micro Air Speaker Cables are made from high-purity oxygen-free copper and arranged in a concentric multi-layer design. This differs from more conventional cable constructions, where individual strands can be distributed in a less controlled way. The concentric structure reduces irregular contact points between wires, harmonises signal flow, and minimises runtime differences that can blur timing and spatial cues.

This means impulses can be reproduced with greater precision, allowing music to retain its fine detail, focus, and dimensional information. A thin layer of polyethylene protects the copper from oxidation, helping preserve long-term performance. Compared with lower-grade alternatives such as copper-coated aluminium, this high-purity OFC copper construction offers superior conductivity, better mechanical resilience, and a more refined, stable listening experience.

A Sound Philosophy Based on Neutrality, Not Coloration

Inakustik’s design philosophy is based on the belief that cables should not impose their own sound on the system. Instead, they should act as discreet and efficient signal paths that minimise filtering effects and interaction with connected electronics. The LS-404 Micro Air Speaker Cables are developed with that exact goal in mind.

Through the combination of air dielectric insulation, low-inductance multicore design, and carefully controlled conductor geometry, the cable reduces losses and electrical side effects that can lead to tonal coloration or reduced clarity. In bi-wire configuration, this philosophy becomes even more effective, helping each part of the loudspeaker receive a cleaner and more stable signal. The outcome is a sound that feels unforced, transparent, and musically coherent, allowing the system’s natural character to come through.

Made in Germany with Precision Craftsmanship

The Inakustik LS-404 Micro Air Speaker Cables are manufactured in Germany in the company’s own facility, where advanced production techniques are combined with meticulous manual assembly. Every cable undergoes extensive functional and mechanical testing after production, ensuring reliable long-term performance and consistent quality.

In addition to technical checks, in-akustik also incorporates listening evaluations during product development, reflecting its commitment to both measurement accuracy and real-world musical performance. The cable is available in a range of lengths and can be fitted with premium terminations, including banana plugs, cable lugs, or Easy Plug connectors, making it well-suited to high-end bi-wire installations.

With its substantial build, precision construction, and carefully developed acoustic performance, the LS-404 stands as a serious loudspeaker cable for demanding music lovers.
