) 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.

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

conditioning test.

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.
