Indicative average supply lead time: 3 weeks
Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 18-inch trasducer wtihin its application range.
Features :
4-inch, fiberglass inside/outside copper voice coil
2000W continuous program power handling
97.5 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
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 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.
Applications :
The L18P400 is ideal for use in applications where incredible power handling,long excursion and perfect control is required.
Ideal for high quality professional bass reflex and bass-horn system.
The transducer's low frequency extension, coupled with its extremely low generation of harmonic distortion,also makes it ideal for use within critical listening applications such as studio monitoring subwoofer system.
