RCF L18P400 18" 1000 Watt Subwoofer

WOOFER

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.

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.
