18 Sound 10NMB420 10-Inch High Input
Neodymium Woofer 8 Ohms
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 Ø 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.
