The compact Electro-Voice FM-12C is a 200-watt, two-way, medium-to-high efficiency, constant-directivity stage vocal monitor. Possible system orientations are at 35°, 45° and 50° to the floor. Its unique coaxial design provides wide-range response and exceptionally small size.

The enclosure is one-piece molded black textured polyethylene utilizing a special molding technique. This technique yields a wall thickness similar to wood cabinets, a rigid structure that is virtually indestructible and a finish that is impervious to nearly all chemicals. The small size (1.25 cubic feet), light weight (29.5 Ib) and convenient molded-in handle at the cabinet's center of gravity make it ideal to carry or set up.

The high-frequency section of the FM-12C utilizes a beamwidth-stabilizing DirektorTM coupled to EV's exclusive high-power-capacity, wide-beamwidth, Super-Dome™ high-frequency driver for the range 1,200- to 18,000-Hz. This combination is mounted coaxially on a specially designed die-cast frame 12-inch low-frequency driver.

The bass section of the FM-12C is a derivative of the EVM- and FORCE- loudspeaker families. It features a low-mass, edge-wound, 2 1/2-inch-diameter voice coil with beryllium copper lead wires, coated with proprietary high-temperature materials. The polyimide voice coil former and the pole piece of the motor structure are vented for increased cooling capabilities under high-power input conditions. The voice coil is driven by a nine-pound magnetic structure mounted to a rigid, yet lightweight, eight-spoke, die-cast aluminum frame for further heat sinking.
