6. Huge 82 mm diameter motor coils are deployed on both sides of the diaphragm in order to
provide for perfectly balanced kinetics. This novel “push pull” is often seen in other
engineering applications, where maximum control and power transfer is required. It can be
compared to a four wheel drive system and its advantages over only two wheel drive. In
cycling it can be seen that high power demands require that the pedals be pushed as well as
pulled. The Woofer could never achieve the control afforded by this design. To achieve the
same control in a Woofer, stiff restoring suspensions are required, that instantly
compromises the transient attack and dynamics of the system.
BORON NITRIDE
The huge Core assembly already affords the motors’ system with a huge
heat sink capacity several orders of magnitude superior to the limits of the
Woofer. To maximise conduction, Boron Nitride has been exploited, a
materials technology that is not yet commercially available! Developed by
an Oxford scientist, it provides for an electrical insulator that is capable of
conducting heat like copper. Boron Nitride is applied to the coil former, to
enhance conduction.
CARBON FIBRE DIAPHRAGM
The powerful push pull motors are capable of handling 500 amperes,
converting over 1,000 watts of electro magnetic energy into kinetic energy.
Huge compression and decompression forces are involved, and this
demands the most advanced materials technology to avoid being literally
torn apart. The most advanced manufacturing technology in the world has
been designed and created by Wilson Benesch in order to form this
material, and you will only see this technology applied in the future, in the
most advanced engineering applications. Once again Wilson Benesch is the
first company in the world to exploit the world’s latest technologies. In this
case the novel weave of the carbon fibre makes multiple axis draping achievable with ease. The
result is the stiffest, lightest and most highly damped diaphragm ever made. It takes the
performance of large diaphragm structures to a level never achieved before. It is in fact so strong,
that the 18gm structure will cope with a mass load in excess of 100,000 times its own mass!
