RCF LF15X401

Very linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 18-inch transducer within its application range.
SKU: LF15X401
Availability: 29 in stock
Manufacturer: RCF

* 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 transducer's 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.
