Prezentare Difuzor LF 8M400F 8''
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. 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 fiberglas former to improve force transmission and power
handling. ISV technology is based on a high strength fiberglas 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. The copper shorting ring on the
pole piece reduces inductance and improves transient response and phase control in the mid
frequencies.
