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 wires of the Premium LS-CU speaker cable are made of particularly high-purity copper. A conductor cross-section of up to 4 mm² provides the basis for a powerful and dynamic sound. Stranded wire is a tried-and-tested conductor design. In the Premium LS-CU, the strands consist of 84 x 0.30 mm (4.0 mm²) wires "braided" together. The advantage of this design lies in the mechanical flexibility, which increases with smaller diameters of the individual wires. For cost reasons, many loudspeaker cables use the same stranded wire with the same stranding direction for both the positive and negative conductors. However, these cables are not easy to lay and tend to get tangled due to the torsional forces acting on the strands in the same direction. This can be remedied by using stranded wires with different stranding directions for the positive and negative conductors. The opposing torsional forces cancel each other out and the cable can be laid more easily and smoothly.

The Premium LS-CU Flat speaker cable is the ideal solution for anyone seeking high-quality audio performance without visible cable clutter. With its extremely flat design of just 4 mm thick, it can be effortlessly routed under carpets, behind baseboards, or along wall edges – invisible and space-saving. The highly flexible conductors consist of the finest braided strands with a 0.7 mm² cross-section per core (total 2 x 2.5 mm²). Unlike rigid stranded constructions, this design offers exceptional flexibility that masters even tight curves and complex routing paths without compromising performance. Perfect for home cinema applications: Whether 5.1-, 7.1-, or even Atmos setups – the LS-CU Flat supplies all speakers with ample power and delivers precise, powerful sound. The high-quality pure copper construction ensures minimal signal loss and natural reproduction that holds up even in demanding scenes. This cable combines functionality with HiFi quality: discreet in use, convincing in sound – the smart choice for modern living spaces and ambitious home cinema builders.

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.
