15 HPL 76W | Woofer
Le
High efficiency 15" woofer using a FEA computer designed high
energy Neodymium magnet assembly, extremely lightweight (only
3.5 kg). The aluminium basket is designed to effectively dissipate
heat during demanding use at full power, reducing power
compression. A special 3" copper voice coil using proprietary high
temperature adhesives guarantee a very good LF dynamic range
with a very low distortion figure. Recommended for bass-reflex
subwoofer enclosures where power is limited to 700W.

1 2 hours test made with continuous pink noise signal (6 dB crest factor) within
the specified frequency range. Power calculated on rated minimum impedance.
Loudspeaker mounted in 110 liters (3.9 cu.ft3) bass-reflex box, tuned at 45 Hz.
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 2000 Hz.
4 Thiele-Small parameters are measured after a high level 20 Hz sine wave pre-
conditioning test.
