PM-40
Commentary

Horn type mid-range unit.

The horn is die-cast (4 mm thick) with a precision finish and achieves uniform directional characteristics up to 13 kHz due to the structure of horn curves and fins.

The driver has a structure that cancels unwanted distortion noise caused by natural vibration and resonance of the edge, improving frequency characteristics and reducing harmonic distortion.
