Mica-Filled Polypropylene
Woofers

The mica-filled polypropylene
cone achieves new standards in
t r a n s i e n t s p e e d a n d d y n a m i c
range because of its phenomenal
rigidity and improved stiffness to
mass ratio. The inverted butyl
surrounds, the BumpBack

mag-

nets and the rigid steel basket
are all optimized for large excur-
sions of the cone. In this way,
each of the HD speakers deliver
exceptionally deep and detailed
bass at realistic sound pressure

levels, without the mechanical-
ly induced limiting and distortion
of typical designs.
