Very long excursion 18” woofer with 1400W power handling for subwoofer
application where excellent reproduction of the lowest frequencies is
mandatory. A special 4" voice coil using proprietary high temperature
adhesives and an optimized magnet assembly guarantee very good LF
dynamic range, low power compression and a very low distortion figure. A
double spider with optimized compliance ensures excellent mechanical
stability even in the hardest working conditions.

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 2000Hz.
4 Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-
ditioning test.
