15 HPL 76W Woofer

High efficiency 15" woofer using a FEA computer designed high energy Neodymium magnet assembly, extremely lightweight (only

3.5kg). 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.
