Product information "LS-CU | Reel"

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.

Description

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 classic speaker cable for all applications, with remarkable electrical properties. Suitable for the home hi-fi, car hi-fi, DJ and home cinema sectors. The compact design brings remarkable performance in a minimum of space, with an optimum price/performance ratio. Perfect for laying - it is extremely flexible and easy to install thanks to conductors with diametrically opposed twist (S/Z). Plus/minus coding for orientation purposes.

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.

LS-Atmos Air
HiFi speaker cable Quality: Exzellenz Atmos AIR

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.
