12-in Woofer ideal for fixed installation or touring professional loudspeaker systems

(No ratings yet)

Key item features

Applications
* The LF12X401 is ideal for use in applications where sizable amounts of low frequency, long excursion and low distortion acoustic power is desired.
* The robust mechanical design and optimised weight of the device make it desirable for use in fixed installation or touring professional loudspeaker systems.
* The transducer's low frequency extension, coupled with its extremely low generation of harmonic distortion, also makes it ideal for use within critical listening applications such as studio monitoring subwoofer systems. 45 1500
