No such thing. Syntor was capable of 10 watts of audio, same as the
amplified speakers. Horn speakers were often used for outside speakers. If
you want more, use the PA function on Siren or separate siren module.
Better to use noise canceling headsets / intercom system in cab to save
hearing on runs. Avoids issues with OSHA.
