The M4 is a 2-way high performance stage monitor employing an integrated 15" LF and 1.3" exit horn loaded HF coaxial driver design that utilizes neodymium magnets. The constant directivity dispersion of 50° x 70° (h x v), which this unique horn provides,delivers an accurately defined coverage area on stage. The M4 can also be operated in 2-Way Active mode.
When the cabinet is used in an upright position the M4 serves as a powerful PA loudspeaker with a 70° x 50° dispersion suitable for a variety of applications. For dedicated installation applications the dispersion characteristics of the M4 driver assembly can be rotated in 45° increments.
M4 cabinet is constructed from marine plywood, which incorporates the handles, has an impact resistant paint finish,M10 threaded inserts and a socket to accept loudspeaker stands.The front of the loudspeaker cabinet is protected by a rigid metal grill backed with an acoustically transparent foam. Two runners recessed in the bottom panel protect the cabinet from scratching and prevents movement.
