The clarifiers are really passive dampers not radiators.They were used to reduce the cabinet resonance at specific bass frequencies. Each clarifier had a strap of lossy damping material fastened to the cone. The resonant freq of each clarifier corresponds to a cabinet resonant peak, so each acts a tuned trap, reducing the amplitude of the associated peak and therefore providing a smoother bass response.
