The Mid and Low frequency adopts a couple of 12″ LF drivers,each driver’s power handling is 450W and two units connect in series. Four 5.5″ MF drivers with high sensitivity are mounted at the rear of the LF drivers to make up a coaxial configuration. The HF section utilizes 2×1.75”(75mm voice coil) with a 90 ° exponential constant horn via plane-wave transducer to make an coherent wave front. This loudspeaker can generate 140 dB peak SPL output.
