12 PZ 32 | Woofer
Le
Long excursion 12" woofer with 800W power handling for
subwoofer application. A special 3" copper voice coil using
proprietary high temperature adhesives and an optimized
magnet assembly guarantees superb LF dynamic range with a
very low distortion. Due to the linear characteristics of the 12
PZ 32, exceptional results are obtained in horn loaded
subwoofer applications.

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