CLS 4-25-40

Loudspeaker Cable Multicore flex

The multicore speaker cable CLS 4-25-40 has a total of 4 conductors, 2 of which with a cross-section of 4.0 mm2 for the bass range, and the other 2 with a cross-section of 2.5mm2 for the high-frequency range. Due to this characteristic stranding design for hi-fi applications, it generates a crystal-clear sound in the high-frequency and pure dynamic sound in the low-frequency range.
