The Reference LS-1203 has the same technological basis as the LS-1603. It also features the high speed waveguides. The actually usable cross section of these circular waveguides remains constant for all sound frequencies. The result: an extremely homogeneous, balanced loudspeaker cable with a wide-ranging sound spectrum.
