The 10NMB520 is a 10" mid-bass transducer created for compact reflex 2-way enclosures. It can be coupled with 1" compression drivers and it can also be used in mid-low sections on modern line-array systems.<br />
Its features and design characteristics make it extremely defined in mid-range frequencies, offering a significant and consistent bottom-end. This also makes it suitable for monitoring applications.<br />
The extremely powerful external neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange. The overall result is the best power to weight ratio available on the market today.<br />
The curvilinear cone, specified with a high damping wood pulp has been designed to achieve the best possible linearity within its frequency range. The in-house developed cone treatment is a humidity repellent and significantly dampens bell-mode resonances.<br />
The 65mm edge-wound voice coil assembly is wound on a strong fiberglas former in order to improve force transmission and power handling.<br />
A proprietary humidity-block cone treatment makes the transducer suitable for outdoor use in adverse weather conditions. In addition, a special coating applied to both the top and back plates makes the 10NMB520B far more resistant to the corrosive effects of salts and oxidization.
