B&C Speakers 12 PL 32 Folheto

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.

4 

Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-

ditioning test.
