General Description
The 12MB1000 is a very high performance 12" midbass driver. It
offers high power handling capability with exceptional sensitivity
over the midbass frequency range. 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 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 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
specifically dedicated 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 the 12MB1000 to be used in humid
environments without damage.
