Premium Speaker Cables

The in‑akustik Premium LS‑SILVER speaker cable combines high-quality materials with precise engineering to deliver dynamic, detailed, and transparent sound reproduction. The conductors are made of high-purity copper – the best electrical conductor after silver under normal conditions. Compared to copper-clad aluminum (CCA), pure copper provides not only superior conductivity but also greater mechanical durability. An additional silver plating on the conductor surface enhances high-frequency performance, providing clear, open, and nuanced detail reproduction. The strand structure is proven and precisely engineered: 30 × 0.25 mm - 1.5 mm² speaker cable 50 × 0.25 mm - 2.5 mm² speaker cable 84 × 0.30 mm - 4.0 mm² speaker cable The wires are twisted together (“stranded”), increasing mechanical flexibility, especially with smaller individual wire diameters. Another advantage of the Premium LS‑SILVER is the opposite strand twisting (S/Z twisting) of the positive and negative conductors. Conventional cables with strands twisted in the same direction can be difficult to route and may tangle. With opposite twisting, torsion forces cancel out, allowing the cable to be handled and installed smoothly and neatly. With conductor cross-sections up to 4 mm², the cable provides a solid foundation for powerful, dynamic, and detailed sound reproduction, suitable for both stereo and home theater applications. The Premium LS‑SILVER is the ideal speaker cable for audiophiles who value high-quality materials, precise construction, and uncolored signal transmission.

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 speaker cable, the strands consist of 30 x 0.25 mm - speaker cable 1.5 mm² 50 x 0.25 mm - speaker cable 2.5 mm² 84 x 0.30 mm - speaker cable 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.

Under normal conditions, copper is the second-best electrical conductor after silver. Compared to inexpensive CCA (Copper Coated Aluminum), copper offers significantly higher conductivity and also provides superior mechanical strength. The conductors of the Premium LS-CU are made from particularly high-purity copper. A conductor cross-section of up to 4 mm² forms the basis for a powerful and dynamic sound performance. Stranded wire is one of the proven conductor constructions. In the Premium LS-CU, the strands consist of 84 x 0.30 mm - Speaker cable 4.0 mm² twisted individual wires. The advantage of this construction lies in its high mechanical flexibility, which further increases as the diameter of the individual wires decreases. For cost reasons, many speaker cables use identical strands with the same stranding direction for both the positive and negative conductors. However, due to the identical torsional forces of the strands, such cables are often more difficult to route and tend to twist or tangle. This issue can be avoided by using strands with opposite stranding directions for the positive and negative conductors. The opposing torsional forces cancel each other out, allowing the cable to be routed 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-14-CU flame-retardant speaker cable has been specifically designed for permanent building installations where both fire safety requirements and reliable signal transmission are essential. Certification according to EN 50575 Class Eca complies with the Construction Products Regulation (CPR) and enables use in professional installation environments. The conductor consists of 50 individual copper strands with a diameter of 0.25 mm each, forming a total cross-section of 2 × 2.5 mm². This construction provides an excellent balance of electrical conductivity and mechanical stability for long-term installations. The talc-coated PVC jacket simplifies stripping and ensures convenient handling during installation. Clear conductor color coding (Red / Blue) allows quick polarity identification, making installation faster and more straightforward. With its robust construction, standards-compliant flame rating, and installation-friendly design, this cable is a reliable choice for speaker wiring in buildings, conference rooms, training facilities, and professional audio installations.

The LS-CU flame-retardant speaker cable is designed for professional audio installations where, in addition to high signal quality, enhanced safety requirements must be met. The flame-retardant construction according to IEC 60332-1-2 Class Eca reduces the spread of flames along the cable, making it suitable for use in buildings and technical installations. The conductors consist of stranded copper wires with 0.25 mm diameter, providing an excellent balance of flexibility and mechanical stability. Depending on the application, the cable is available with a 2 × 1.5 mm² or 2 × 2.5 mm² cross-section, making it suitable for both compact audio installations and higher-power speaker systems. The extruded PVC jacket is easy to strip and facilitates quick handling during installation. Clear red/black conductor coding simplifies correct polarity assignment when connecting speakers. With its robust construction, standards-compliant flame rating, and excellent installation properties, the LS-CU is a reliable solution for public address systems, home theater setups, or professional audio cabling in buildings.
