The most powerful 18" in our product range, 2000 W continuous program
power handling, defines the "state of the art" about LF reproduction. A
four inch copper wire voice coil with very high thermal capability and a
ventilated magnet assembly allows a low power compression. A very low
distortion figure is obtained using a double spider design and dual
demodulation rings in the magnetic path. Proprietary water-proof cone
treatment for safe use in adverse climatic conditions.
