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 reaches its maximum excursion limits.
