The copper shorting ring on the pole piece reduces inductance and provides improved transient response and phase control on the mid frequencies. The 50 mm diameter state-of-the-art, copper wire voice coil employs the same technology fitted to our top-of-the-range models, i.e. our Interleaved Sandwich Voice coil (ISV). This technology consists of a high strength fiberglas former carrying windings on both the outer and inner surfaces, creating a mass balanced coil. This results in an extremely linear motor assembly which, in conjunction with the highly advanced design of the magnetic structure, provides a high force factor or BL. Another advanced design feature of the 10MB400 is the air channel fine passages between the chassis back plate and top plate of the magnet. These passages are used to draw heated air out from the voice coil gap and dissipate the energy via the chassis casting. The top and back plates of the magnet assembly have been designed to optimise flux density and BL factor in the air gap using our in-house FEA CAD facility.
