The 10NMB420 neodymium transducer has been developed in response to a specific market
requirement for a 10-in midbass driver that combines excellent linearity with good efficiency and
high power handling capabilities. The 10NMB420 is primarily intended for use as a midbass
driver in line-arrays as well as high quality 2-way or multiway reflex enclosures. The low pass filter
might be positioned as high as 2000Hz. The extremely powerful external neodymium magnet
assembly assures high flux concentration, low power compression and excellent heat exchange.
The levels of force factor and power handling are, as a consequence, at the upper professional
level with best power to weight ratio.
The 65mm of state-of-the-art, aluminum wire voice coil employs Interleaved Sandwich Voice coil (ISV) technology.
It is composed by a high strength fiberglas former used to carry windings on both the outer and inner surfaces, in order to achieve a mass balanced coil. This results in an extremely linear motor assembly which, in conjunction
with the highly advanced design of the magnetic structure, provides a high BL force factor.
The voice coil is cooled through airways placed between the chassis back plate and the magnet
faceplate. In this way heated air is channeled away from the voice coil and the gap. Another
technology present into the 10NMB420 is the SDR (Single Demodulating Ring), used to
reproduce instantaneous peak on mid frequencies, reducing intermodulation distortion. Thanks
to the increasing use during outdoor audio events, the ability to perform in humid
environments is an extra key feature of the 10NMB420. This is achieved trough an exclusively
developed cone treatment which renders the cone humidity repellent while does not increasing
the total moving speaker mass.
