The 8M400 is a high power, high output, 200mm(8in) mid-range for high level professional use.
The excellent sound quality has been achieved as a result of extensive research on mid
The 8M400 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 w/a
high damping wood pulp, has been designed to achieve the best possible linearity within its
The in-house developed cone treatment is a humidity repellent & also
dampens the bell mode resonance significantly.
The 51mm (2in) ISV aluminum voice coil
assembly is wound on a strong fiberglass former to improve force transmission & power
ISV technology is based on a high strength fiberglass former w/half the coil wound on the outside & half on the inside & bonded together using unique high temperature resin adhesives.
The powerful magnet assembly assures high flux concentration.
The force factor & power handling are at an optimum level.
The direct contact between the finned basket & the magnetic structure significantly improves thermal connection & heat dissipation, further increasing power handling & lowering power compression.
The copper shorting ring on the pole piece reduces inductance & improves transient response & phase control in the mid frequencies.
