Description
The 12MB1000 is a very high performance 12" ferrite midrange driver. It offers high power handling capability with exceptional sensitivity over the middle frequency band. It can be used with either direct radiating or horn loaded applications, as well as part of a 2 or 3-way system. It is ideally used in stage monitor, auditorium, touring and outdoor systems.
The 12MB1000 is the result of an intensive development program which aimed to produce the best 12" midrange driver possible.
The smooth curvilinear paper cone has a special high strength wood pulp composition designed to achieve the best possible linearity within the middle frequency range and to control bell-mode resonances around the cone. The cone is carried by a double half-roll suspension, which is more resistant to aging and fatigue than traditional materials, and provides the correct dampening and excursion control.
The state-of-the-art voice coil employs our own Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglas former carries windings on both the outer and inner surfaces. By mean of a balanced coil with uniform distribution of mass and motive energy, this technology assures an extremely linear motor assembly.
The voice coil cooling has been achieved by incorporating airways between the chassis back plate and the top plate of the magnet which allow heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket. This technology is the result of a meticulous design exercise using a sophisticated in-house 3D CAD facility. The magnetic structure has also been optimized using our in-house FEA CAD resource to maximize flux density in the voice coil gap.
Eighteen Sound R&D has developed a special cone treatment designed to improve the dampening properties of the moving assembly, thus considerably improving the transient response control. This treatment also gives water repellent properties to the cone, enabling the12MB1000 to be used in humid environments without damage.
