The speaker offers a superb linearity: distortion values are further minimized by new enhanced design criterias, taking the 6NMB900 to very high level of performance. 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. A consistent heat transfer is guaranteed by the encapsulation of the magnetic structure in the interior of the basket, offering a large contact space between the back plate and the dissipating structure. Particular efforts were dedicated to the new surround shape and material design, in order to minimize the resonances on mid range frequencies. The new multiroll design offers a consistent damping to typical bell modes. The 44 mm voice coil is made of light-weight aluminum wire and assures linearity and high power handling. The ability to perform in humid environments is a key feature of the 6NMB900: this is achieved through a proprietary humidity repellent cone treatment.
