18" ferrite magnet, cast aluminium chassis LF driver delivering 1000Wrms (AES Standard) power handling and 98dB sensitivity
4" high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing performance loss through thermal compression
Triangulated coil reinforcement reduces moving mass, thereby increasing sensitivity, while maintaining a long Xmax
Finite element analysis optimised magnet assembly delivers remarkably low harmonic distortion and very high motor strength
