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.

Long excursion 15" woofer with 1400W power handling for

subwoofer application. A special 4" voice coil using

proprietary high temperature adhesives and an optimized

magnet assembly guarantees a very good LF dynamic range

with a very low distortion figure. Recommended for

compact bass-reflex enclosures.
