RCF L18P400 1000W AES 18″ Driver 8 Ohm Four Pack

PRODUCT CODE: RCFL18P400_4PK

Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of anycomparable 18-inch trasducer wtihin 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 RCf Precisions 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 transducers 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.

Main Features:
