Celestion FTR18-4080FDX Pro DJ/Club 18" Ferrite Subwoofer Sub 800W RMS
Features:
-
18" ferrite woofer provides 800Wrms power handling (AES standard) and 96dB sensitivity
-
4" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
-
FEA optimised magnet assembly provides low harmonic distortion and very high motor strength
-
Ribbed, straight-sided, glass-loaded cone, with FlexirolTM surround for greater excursion control
-
Double suspension for exceptional linearity at the highest excursions
-
Smart chassis design minimises acoustic distortion
