RCF LF15X401 Speaker Woofer 4 Inch 8 Ohm 3000 Watt
Speaker Woofer 4 Inch 3000 Watt 30 Hz – 1.5 kHz
Description
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. The LF15X401 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.
