The special composite cone is built with non-pressed paper for reduced break-up and treated to be water resistant, delivering a smooth frequency response and a low moving mass, increasing the efficiency of the speaker, with a generous 1.65″ peak-to-peak excursion before damage. Extensive motor venting cools the voice coil enabling high power handling with low power compression. The large 3″ voice coil allows for 1200 Watts of Amplifier RMS Power, and warrants the outstanding cooling system implemented into the motor.
