Description

The 10NMBA520 is the evolution of the 10NDA520. The transducer is a 10" mid-bass transducer created for compact reflex 2-way enclosures, and when compared to 10NDA520 shows 1 dB increased sensitivity over all operative frequency range, as well as 600 Watts program power handling. It can be used in mid-low sections on line-array systems and everywhere very high quality mid-bass frequency range reproduction is needed. The 10NMBA520 incorporates Active Impedance Control technology (AIC), consisting of an additional coil fixed on the pole piece and connected in parallel to the moving coil. The magnetic field generated by AIC coil has the following effects: 1) Impedance linearization 2) Acoustic and electric phase linearization 3) Significant increase of sensitivity and total SPL 4) Total harmonic distortion reduction 5) Constant power transfer By not absorbing the moving coil's electromagnetic energy, the AIC offers substantial advantages to the sound quality. The external neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange. The curvilinear cone, specified with a high damping wood pulp has been designed to achieve the best possible linearity within its frequency range. The 65 mm (2,5 in) diameter aluminum voice coil is wound on a strong fiberglas former in order to improve force transmission and power handling. A special coating applied to both the top and back plates makes the 10NMBA520 far more resistant to the corrosive effects of salts and oxidization.
