- Ideal for direct radiating or horn loaded midbass systems
The 12MB1000 is a very high performance 12" midbass driver. It offers high power handlingcapability with exceptional sensitivity over the midbass frequency range. It can be used witheither direct radiating or horn loaded applications, as well as part of a 2 or 3-way system. It isideally used in stage monitor, auditorium, touring and outdoor systems. The smooth curvilinearpaper cone has a special high strength wood pulp composition designed to achieve the bestpossible linearity within the middle frequency range and to control bell-mode resonancesaround the cone. The cone is carried by a double half-roll suspension, which is more resistant toaging and fatigue than traditional materials, and provides the correct dampening and excursioncontrol. The state-of-the-art voice coil employs our Interleaved Sandwich Voice coil (ISV)technology, in which a high strength fiberglas former carries windings on both the outer andinner 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 beenachieved by incorporating airways between the chassis back plate and the top plate of themagnet which allow heated air from the voice coil and gap to be channeled away and dissipatedby the chassis basket. This technology is the result of a meticulous design exercise using asophisticated in-house 3D CAD facility. The magnetic structure has also been optimized usingour in-house FEA CAD resource to maximize flux density in the voice coil gap. Eighteen SoundR&D has developed a special cone treatment specifically dedicated to improve the dampeningproperties of the moving assembly, thus considerably improving the transient response control.This treatment also gives water repellent properties to the cone, enabling the 12MB1000 to beused in humid environments without damage.
