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.

High efficiency 15" woofer with a very flat frequency

response up to 2 kHz and high power handling (800W). Good

LF performance, smooth voice response, and compatibility

with compact bass-reflex enclosures, the 15 PK 40  achieves

perfect balance in  two-way systems.
