Speaker Pro A Bi-Wiring cable for wiring acoustic devices to amplifier unit, designed as Bi/Tri- wiring in addition to Speaker Pro A mk2. The cable may be referred to as a tweeter-cable for its reduced cross-section (2.5 mm²) of the multicore OFC conductor in comparison to the standard model. Recommended to use together with standard cross-section cable only for high-frequency register connection (tweeter or super tweeter bands). Outer insulation: cotton, dyed with black natural dyes.

The cable has been fitted with tight spring-loaded banana connectors at the both ends. Natural gold plating provides good wear resistance of connectors.
