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.
