RCF L18P400
2000W Transducer

OUR PART #  L18P400


RCF's L18P400 offers incredibly linear frequency response characteristics and extreme high power handling while generating the lowest harmonic distortion of any comparable 18" transducer wtihin its application range.

The L18P400 uses a fiber loaded cone assembly along with a high excursion triple roll, constant geometry surround.  A fully optimized 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 reachees its maximum excursion limits.  Forced air venting system.
