RCF LF12X401 - 12" 1000W 8 Ohm
THIS ITEM IS END-OF-LINE AND DUE TO BE PHASED OUT
If it is not showing in-stock, please email us to double-check the availability.
Very linear frequency response characteristics, extremely high power handling while generating the lowest harmonic distortion of any comparable 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 60 mm. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling.
The LF12X401 is ideal for use in applications where sizeable amounts of low frequency, long excursion and low distortion acoustic power are desired. The robust yet compact mechanical design and optimised weight of the device make it desirable for use in fixed installation or touring professional loudspeaker systems.
The transducer's superb 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.
