B&C Speakers Woofer 12 PL 32 User manual

High efficiency 12" woofer with a very flat frequency response
up to 2 kHz and high power handling (700W). Where good LF
performance in compact bass-reflex enclosure is required, the
12 PL 32 represents an optimal choice for a two-way system.

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 3500 Hz.
Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-
ditioning test.
