Description

The 12ND710 has been specifically designed for use either as a midbass
driver in compact 2-way reflex enclosures or as a direct radiating or
horn loaded, dedicated midrange driver, in multi-way touring and fixed
installation concert and arena systems.
The
neodymium magnet assembly assures high flux concentration, low power
compression and excellent heat exchange because the external magnet
configuration is considerably more efficient than traditional
under-pole magnet topology.
Consequently, high levels of force factor and power handling with an optimum power to weight ratio have been achieved.
Direct
coupling of the special design basket and magnetic assembly with the
large heat sink facilitates thermal flux through the ambient air,
increasing the power handling capabilities and lowering the power
compression.
The curvilinear paper cone has been created with a
special high strength wood pulp designed to achieve the best possible
linearity within its intended frequency range and to control bell-mode
resonances around the cone circumference. The cone is carried by a
multiroll suspension formed from a linen-like material which is more
resistant to aging and fatigue than traditional materials.
The
already low distortion and sound quality are further improved by the
use of Double Demodulating Rings technology (DDR) designed to
dramatically reduce the intermodulation and harmonic distortion and
improve the transient response.
The 12ND710 implements Interleaved
Sandwich Voice coil technology (ISV), in which an aluminum coil is
wound inside and outside a high strength fiberglas former, providing a
better thermal and mechanical performance than conventional coils.
A
proprietary humidity-block cone treatment makes the transducer suitable
for outdoor use in adverse weather conditions. In addition, a special
coating applied to both the top and back plates makes the 12ND710 far
more resistant to the corrosive effects of salts and oxidization
