• The 8M400F is a high power, high output, 200 mm (8 in) midrange for high level professional use. The excellent sound quality has been achieved as a result of extensive research on mid frequencies intelligibility. The 8M400F has been designed for use as a midrange in both horn and direct radiation, closer or reflex enclosures, as small as 3 lt. The curvilinear cone, made with a high damping wood pulp, has been designed to achieve the best possible linearity within its frequency range.
• In-house developed cone treatment is a humidity repellent & also dampens the bell mode resonance significantly. The 51 mm (2 in) ISV aluminum voice coil assembly is wound on a strong fiberglas former to improve force transmission & power handling. ISV technology is based on a high strength fiberglas former w/ half the coil wound on the outside & half on the inside & bonded together using unique high temperature resin adhesives. Powerful magnet assembly assures high flux concentration.
