Our model 414-8B (16B) is a 12 in. (305 mm) low frequency loudspeaker. Because of its size, our 414-8B (16B) loudspeaker is ideal for use in moderately dimensioned sound reinforcement and high-fidelity applications.

This loudspeaker features a structurally reinforced, die-cast, aluminum frame. The frame’s 8 mounting bolt slots will accept a 0.25 in. (6 mm) diameter bolt or smaller, allowing the loudspeaker to be attached to almost any secure surface by either a front mounting or rear mounting method.

Also featured is a 1.8 lbs. (0.8 kg) AlNiCo V magnet, which produces an at-rest gap flux density of 0.9 T. Another feature is the 3 in. (76 mm) diameter, edge-wound, copper-ribbon voice-coil. This voice-coil is attached to a high grade fiber cone. The cone is secured to the frame with a high compliance cloth surround.
