8-in mid-range for high level professional use 8-Ohms

The 8M400 is a high power, high output, 200mm8in mid-range for high level professional use.The excellent sound quality has been achieved as a result of extensive research on midfrequencies intelligibility. The 8M400 has been designed for use as a midrange in both horn anddirect radiation,closer or reflex enclosures, as small as 3 lt. The curvilinear cone,made w/ahigh damping wood pulp, has been designed to achieve the best possible linearity within itsfrequency range. The in-house developed cone treatment is a humidity repellent & alsodampens the bell mode resonance significantly. The 51mm 2in ISV aluminum voice coilassembly is wound on a strong fiberglass former to improve force transmission & powerhandling. 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.Class D amplifier optimized for maximum power transfer Conforms to PowersoftTM iPal standards 94.2 dB SPL 1W / 1m average sensitivity 135mm 5.3-in split winding. four layer ISV aluminum voice coil 400 W program power handling Triple Silicon Spider TSS for improved excursion control Aluminum demodulating ring SDR for lower distortion Nominal Diameter 200 mm 8 in Rated Impedance 8 Ohm AES Power 280 W Program Power 400 W Peak Power 800 W Sensitivity 95 dB Frequency Range 60 - 4500 Hz Power Compression -10dB 0.5 dB Power Compression -3dB 1.4 dB Power Compression Full Power 2.3 dB Max Recomm.
