Description
The 10NMB420 neodymium transducer has been developed in response to a
specific market requirement for a 10? 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
? 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.
