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 2500 Hz.

Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-
ditioning test.
12 PS 32 | Woofer
This 12" woofer with 1400W maximum power handling is
recommended for the most demanding sound reinforcement
application. A special 4" voice coil using proprietary high
temperature adhesives and an optimized magnet assembly
guarantee a very good LF dynamic range with a very low
distortion figure Sub compact reflex systems set new standards
employing the ultra high power 12 PS 32.
