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.
