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.

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 preconditioning
test.
