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.

SPECIFICATION
12” neodymium woofer offers 300Wrms (AES) continuous power handling and 98dB sensitivity
3” high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
M-roll surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range
Extremely lightweight design combined with a highly efficient magnet assembly results in exceptional power-to-weight ratio
Intelligent heat management in both chassis and magnet assembly design further minimizes distortion
