Incredibly 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 LF18X400 uses a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround. A
fully optimised T-pole design generate the minimum amount of flux modulation. The T-pole also features RCF Precision’s spaced gap demodulation technology, progressively braking the voice coil, providing a much smoother transition for the moving mass as it reaches its maximum excursion limits. Forced air venting system.
