2000 Watt continuous program power handling 97. 5 dB Sensitivity
4-inch, fibreglass inside-outside copper voice coil 2000 Watt continuous program power handling 97. 5 dB Sensitivity
25 Hz - 1 kHz Frequency range Aluminum demodulation ring Forced air ventilation and 14 mm top plate for minimum power compression
Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry
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 L18P400 uses a fiber loaded cone assembly along with a high excursion triple roll, constant geometry surround. A fully optimized T-pole design generates the minimum amount of flux modulation. The T-pole also features RCF Precision's spaced gap demodulation technology, progressively breaking the voice coil, providing a much smoother transition for the moving mass as it reaches its maximum excursion limits. Forced air venting system.
