Woofer
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.
