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.
