18 SOUND 8M400FC 8 inch Midrange For High Level Professional Use 250 Watts With 18 Sound on Curvilinear Cone 8 Ohms. || 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. || 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. || || The in-house developed cone treatment is a humidity repellent and also dampens the bell mode resonance significantly. || The 51 mm (2 in) ISV aluminum voice coil assembly is wound on a strong fiberglass former to improve force transmission and power handling. || ISV technology is based on a high strength fiberglass former with half the coil wound on the outside and half on the inside and bonded together using unique high temperature resin adhesives. || The powerful magnet assembly assures high flux concentration. || || The force factor and power handling are at an optimum level. || The direct contact between the finned basket and the magnetic structure significantly improves thermal connection and heat dissipation, further increasing power handling and lowering power compression. || || * Nominal Impedance: 8 Ohms. || * Minimum Impedance: 6.5 Ohms. || * Nominal Power Handling: 250 W. || * Continuous Power Handling: 320 W. || * Sensitivity: 100.5 dB. || * Frequency Range: 200 - 9000 Hz. || * Voice Coil Diameter: 51 mm (2.0 in). || * Recommended Enclosure: 6.0 dm3 (0.21 ft3). || * Recommended Tuning: 100 Hz. || * Resonance Frequency: 89 Hz. || || * Overall Diameter: 210 mm (8.27 in). || * Bolt Circle Diameter: 196 mm (7.74 in). || * Baffle Cutout Diameter: 186.0 mm (7.32 in). || * Depth: 106 mm (4.17 in). || * Flange and Gasket Thickness: 15 mm (0.61 in). || * Net Weight: 4.9 kg (10.8 lb). || * Shipping Weight: 5.2 kg ( lb). || * Shipping Box: 235x235x150 mm (9.25x9.25x5.91 in).
