The LF12X401 is ideal for use in applications where sizable amounts of low frequency, long excursion and low distortion acoustic power is desired.
4.0 - inch, fibreglass inside-outside copper voice coil
2000 Watt continuous program power handling
96.5 dB Sensitivity
45 Hz – 1.5 kHz Frequency range
26.1 T/m BL
60 mm peak-to-peak excursion
Dual-forced hyper-venting and 15mm top plate for minimum power compression
Dual spider design with silicon based dampening control
Triple-roll surround and curved cone geometry
Very linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 12-inch transducer within its application range. The LF12X401 uses a fibre loaded cone assembly along with a high excursion triple roll surround. This combination provides remarkable strength and a peak to peak maximum excursion of 50 mm. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling.
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.
