Speaker Cables by the Meter

The Referenz LS-1102 has 6 conductors, each with 37 concentrically stranded wires. The cores are in triple symmetry and have been specifically arranged in the CC-187 design to keep the inductance low and the resistance linear. The larger cable cross-section ensures excellent and controlled bass reproduction and high efficiency. Polyethylene (PE) already boasts excellent electrical properties for audio, video and digital cables. The foaming process generates an air content in this dielectric, which further diminishes any annoying battery-like cable capacitance. The reproduction gains even greater brilliance and spatiality. A layer of solid PE protects the foamed PE from mechanical influences. 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-1102, reduce this effect and bring more precision and punch to the sound. With conventionally stranded wires, the individual strands run chaotically through the conductor. This leads to undefined contact points, which can result in degraded signal transmission. In contrast to this, each wire in the Concentric Copper structures has a precisely defined position within the conductor. This enables homogeneous signal transmission and ensures crystal-clear audio reproduction.

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.
