Key item features

The LF15X401 is ideal for use in applications where sizable amounts of low frequency, long excursion & low distortion acoustic power is desired
The robust mechanical design & optimised weight of the device make it desirable for use in fixed installation or touring professional loudspeaker systems.
The transducers low frequency extension, coupled w/its extremely low generation of harmonic distortion, also makes it ideal for use within critical listening applications such as studio monitoring subwoofer systems. 34 1500
