The conductors of the LS-20 are made of high-purity copper. Under normal conditions, copper is the next-best electrical conductor after silver. Compared to cheap CCA (Copper Coated Aluminum) in particular, copper has a significantly better conductivity and is also mechanically more resilient. The stranded wire design is a tried and tested conductor design in the hi-fi sector. Each conductor consists of 50 x 0.25 mm strands that are "twisted" together. The advantage of this design lies in the economical production and the mechanical flexibility, which increases with smaller diameters of the individual wires.The conductor cross-section of 2x2.5 mm² forms the foundation for a dynamic and powerful sound. The polyethylene (PE) insulation of the LS-40 has very good electrical properties. Compared to PVC, it halves the annoying battery-like capacitance of cables. The reproduction gains in brilliance and spatial quality. The PE network jacket protects against mechanical damage and serves as additional insulation.

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-40, reduce this effect and bring more precision and punch to the sound. The conductors of the LS-40 are made of high-purity copper.

The LS-Atmos AIR speaker cable uses Atmos AIR technology to create optimal conditions for precise signal transmission. The design aims to utilize air - an ideal dielectric—as extensively as possible between the signal conductors. At the center of the electric field between the conductors, a defined air chamber is integrated into the cable structure. This reduces capacitance and dielectric losses and helps preserve the integrity of the audio signal. Another key feature is the Concentric Copper conductor design. Each individual copper strand is positioned in a precisely defined location within the conductor. Unlike conventional stranded constructions, where the relative position of the strands continuously changes, this geometry remains stable. The result is consistent electrical properties and controlled signal transmission. The combination of air insulation and a precisely defined conductor geometry supports transparent, detailed sound reproduction with excellent dynamics and natural tonal balance. The LS-Atmos AIR speaker cable is designed for demanding hi-fi enthusiasts who value high-quality materials, thoughtful engineering, and accurate signal transmission.

The LS‑MSR speaker cable is part of in‑akustik’s excellence series and uses the classic MSR technology, based on proven designs from the 1990s. The cable features a twin‑line construction with generous conductor cross-sections, providing a solid foundation for powerful and controlled signal transmission. The conductors are made of high‑purity copper, which offers excellent conductivity and mechanical resilience compared to copper-clad aluminum (CCA) alternatives. This ensures consistent electrical performance and long-term reliability. The fine-stranded conductors 651 x 0,07 mm - speaker cable 2,5 mm² 1050 x 0,07 mm - speaker cable 4,0 mm² 1575 x 0,07 mm - speaker cable 6,0 mm² give the cable high flexibility, making installation and routing easier. Clear plus/minus identification via color coding allows for straightforward connection. The LS‑MSR is sold as metered cable and can be fitted with connectors according to system requirements. The LS‑MSR speaker cable is suitable for hi-fi setups where solid electrical fundamentals, flexibility, and reliable signal transmission are a priority.

The S25 Speaker 425 is the most powerful model in the series, designed for audiophile setups with high power reserves and long cable runs. The large conductor cross-section and low-inductance multicore design ensure exceptionally low-loss transmission – even under high load or long cable lengths. The sound benefits from a particularly controlled, deep-reaching bass with precise punch, clearly defined mids, and an open, detailed high-frequency reproduction. The spatial presentation is stable and wide. Thanks to high-quality materials such as fine-stranded OFC copper, solid crimp contacts, and gold-plated connectors, the signal remains unaltered along the entire length. Its discreet, functionally elegant design and surprisingly high flexibility despite the large cross-section allow for neat, unobtrusive installation – even in complex rack setups or close to walls.
