The 15MB606 high output mid bass has been designed for use as a bass and low-midrange driver in tuned reflex enclosures, in 2-way systems. It combines high sensitivity (101dB 1W/1m) with high power handling capability. The smooth textured curvilinear paper cone, in conjunction with the viscose dampened multiroll suspension, provides excellent cone dampening and excursion control. The 75 mm Ø aluminum voice coil employs our Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglas former carries windings on the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard. The low inductance coil results in improved transient response. Excellent heat dissipation has been achieved by incorporating air channels in the basket design, between the basket and top plate. Maximum flux concentration and force factor in the gap are assured by the unique shape and design of the top and back plates, which was created using Magnetic Flux FEA CAD simulation. A special treatment is applied to the top and the back plate which increases their resistance to the corrosive effects of salts and oxidization. This treatment is more effective than any other treatment in use today by other manufacturers.
