The LS-1603 SILVER controls all facets of the sound spectrum: from the subtle symbol clash of a jazz percussionist to the sententious voice of a female soul singer to the roaring final chord of a symphony orchestra. The basis for this is the specially developed high-speed waveguide technology. Oxygen-free copper (OFC) wires are wrapped around a polyethylene core and provided with the proven DUO-PE II insulation. The LS-1603 has 16 of these high-speed waveguides, which are finely tuned to each other and stranded in groups around a Polyethylene support (16-fold multicore). To augment the high-speed waveguide conductor design, the surface of each individual copper wire is silver-plated. This is a more conductive material for high frequencies that are carried on the conductor surface due to the skin effect, and the complex music signal is carried with less loss. This is yet another fine-tuning for crystal clear sound.
