The 12MB606 ferrite mid bass transducer meets the specific market requirement for a loudspeaker combining good linearity and efficiency with high power handling capabilities.
The 12MB606 is an ideal low frequency ferrite driver choice for two-way systems where the balance between low frequency
reproduction and midrange precision is required. Although primarily developed for midbass use, the 12MB606’s versatile characteristics render it suitable for compact reflex subwoofers (around 50-55 lt).
The curvilinear paper cone has been made with a special high strength wood-pulp designed to achieve the best possible linearity within its intended frequency range and to control bell-mode resonance around the cone circumference.
The cone is carried by an unusually deep profile, double roll polycotton suspension.
The suspension geometry has been carefully designed for superior symmetry, resulting in DC offset free movement in the lowest frequency area.
The 75 mm state-of-the-art voice coil is similar to those fitted to our top-of-the-range 18" and 15" models but it is wound with aluminum wire. It employs our Interleaved Sandwich Voice coil (ISV) technology in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. The result is an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.
The ferrite magnetic structure has been optimized using FEA CAD simulation software to maximize the flux density and symmetry in the voice coil gap region and to minimize weight. A lightweight aluminum basket contributes to an excellent weight to performance ratio for a ferrite driver.
Due to the increasing use of audio systems at outdoor events, the 12MB606’s ability to perform in adverse, high humidity weather conditions is another excellent feature. This has been achieved by means of a proprietary water-repellent cone treatment.
