RECOMMANDATION FOR SPEAKER CABLES
Cable quality and resistance
Only use high-quality fully insulated speaker cables made of stranded copper wire.
Use cables of gauge offering low resistance per unit length and keep the cables as short as possible.
The following table provides the recommended maximum length depending on the cable cross-section and on the
impedance load connected to the amplifier.
