M4 is a two-way high performance stage monitor with a maximum sound pressure level of 134 dB. It consists of a 1.3 inch exit coaxial and one 15 inch neodymium woofer. Its constant pointing diffusion angle 50° x 70° (h x v) can accurately cover the stage area, and M4 can also serve as a powerful main expansion system. The M4 cabinet closure is made of good quality plywood and is coated with a layer of durable paint. There are two screw holes on each side panel for flexible mounting and a jack for speaker bracket mounting. Two chutes extending from the rear to the front of the box protect the bottom panel from scratching.
