18" ferrite magnet, cast aluminium chassis LF driver delivering 1200Wrms (AES Standard) power handling and 98dB sensitivity
4" high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing sensitivity loss through thermal compression
FEA optimized magnet assembly and suspension deliver highly symmetrical cone movement, leading to exceptionally low harmonic distortion
Vented magnet assembly increases airflow to provide enhanced cooling
Twin demodulation rings reduce flux modulation, minimizing electromagnetic distortion
Double suspension and "multi-roll" surround provide exceptional linearity at extremes of cone excursion
