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.

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.
