8-in High Power Low Frequency Driver with neodymium transducer 8 OHMS

95 dB SPL 1W / 1m average sensitivity 51mm 2 in Interleaved Sandwich Voice coil ISV 280 W AES power handling External neodymium magnet assembly Single Demodulating Ring SDR for lower distortion Weather protected cone and plates for outdoor usage Suitable for line arrays and compact two way systemsThe 8NMB420 neodymium transducer has been developed in response to a specific marketrequirement for a 8-in midbass driver that combines excellent linearity with good efficiency and highpower handling capabilities. 8NMB420 is primarily intended for use as a midbass driver in compact 2-way or multiway reflex enclosures comprising line arrays. The parameters had been chosen to offersignificant low frequency output in vented enclosure with size starting from 20 lit. with a tuningfrequency around 60Hz. The low pass filter might be positioned as high as 2000-2500Hz. Multiple8NMB420 units might be used: the compact size reflects in the capability to have precise attack time.This characteristic makes it the ideal choice for stage monitoring and bass guitar amplification. Theextremely powerful external neodymium magnet assembly assures high flux concentration, low powercompression and excellent heat exchange. The levels of force factor and power handling are, as aconsequence, at the upper professional level with best power to weight ratio. The exclusivededicated double roll surround design offers enhanced linear travel and control, in order toreproduce precisely low frequency. The curvilinear paper cone is formed using a unique wood pulpcomposition designed to achieve the best possible rigidity and stiffness. The 50mm inside outsidealuminum voice coil employs Interleaved Sandwich Voice coil ISV technology. It is composed by ahigh strength fiberglass former used to carry windings on both the outer and inner surfaces toachieve a mass balanced coil. This results in an extremely linear motor assembly which, inconjunction with the highly advanced design of the magnetic structure, provides a high force factoror BL. The voice coil is cooled incorporating airways between the chassis back plate and the magnetfaceplate so that heated air is channeled away from the voice coil and gap and dissipated by thechassis basket. Thanks to the increasing use during outdoor audio events, the ability to perform inhumid environments is a key feature of the 8NMB420. This is achieved trough a proprietary humidityrepellent cone treatment without a movin
