The 10NMB500 neodymium mid-bass transducer has been developed in response to a specific market requirement for a ultra light weight 10” midbass driver that combines excellent linearity with high efficiency and good power handling capabilities.<br />
The 10NMB500 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 3000Hz.<br />
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.<br />
The 51 mm (2 in) copper voice coil assembly is wound on a strong fiberglas former to improve force transmission and power handling.<br />
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.<br />
The copper shorting ring mounted on the pole piece reduces inductance and improves transient response and phase control in the midrange frequencies region.<br />
Thanks to the increasing use during outdoor audio events, the ability to perform in humid environments is an extra key feature of the10NMB500. This is achieved trough an exclusively developed cone treatment which renders the cone humidity repellent while does not increasing the total moving speaker mass.
