CELESTION FTR18-4080FDX Ferrite Series Professional Loudspeakers

> 18" ferrite woofer provides 600Wrms 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
