RCF L18P400 18" Woofer
Features
- 2000W continuous program power handling.
- 5 dB Sensitivity.
- 25 Hz – 1 kHz Frequency range.
- Aluminum demodulation ring.
Description
The successor to the legendary RCF L18P300, the RCF L18P400 18" Woofer subwoofer speaker is intended for use in applications where incredible power handling, long excursion, and perfect control are required. It is ideal for high-quality professional bass reflex and bass-horn speaker systems.
Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 18-inch trasducer within its application range.
The L18P400 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 the 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.
Key Features:
- 4-inch, fibreglass inside/outside copper voice coil.
- 2000W continuous program power handling.
- 5 dB Sensitivity.
- 25 Hz – 1 kHz Frequency range.
- Aluminum demodulation ring.
- Forced air ventilation and 15mm top plate for minimum power compression.
- Dual spider design with silicon-based dampening control.
- Triple roll surround and corrugated straight cone geometry.
