1 2 hours test made with continuous pink noise signal (6 dB crest factor) within
the specified range. Power calculated on rated minimum impedance.
Loudspeaker in free air.
2 Power on Continuous Program is defined as 3 dB greater than the Nominal rating.
3 Applied RMS Voltage is set to 2.83V for 8 ohms Nominal Impedance. Average
SPL from 200 to 1200Hz.
Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-
ditioning test.

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.
