Long excursion 12" woofer with 800W power handling for subwoofer application. A special 3" copper voice coil using proprietary high temperature adhesives and an optimized magnet assembly guarantees superb LF dynamic range with a very low distortion. Due to the linear characteristics of the 12 PZ 32, exceptional results are obtained in horn loaded subwoofer applications.
