Description

The 15ND930 is a high power, high output, extended low frequency
neodymium transducer which meets the most stringent requirements in
high quality professional transducers. The high level of performance
and sound quality have been achieved by exploiting the most advanced
technologies available today.
Thanks
to its versatility, the 15ND930 can be used in 2-way compact reflex
enclosures with a 1.4″ compression driver, in multiway systems and in
high loading sub woofers as small as 70 lt (compact reflex, bandpass
and horn loaded configurations).
The neodymium magnet assembly
assures high flux concentration, low power compression and excellent
heat exchange, since the external magnet configuration is considerably
more efficient than traditional under-pole magnet topology. This
results in high levels of force factor and power handling with an
optimum power to weight ratio.
The direct contact between the large
heat sink and basket, together with the magnetic structure, represent a
fundamental improvement in thermal connection and heat dissipation.
Hence, power handling capabilities are increased and power compression
lowered.
The deep profile curvilinear cone, created from a special
high strength wood pulp, has been designed to achieve the best possible
linearity within its frequency range. The cone surround, made from a
linen material is highly resistant to aging and fatigue. The in-house
developed cone treatment is a humidity repellent and significantly
dampens bell mode resonances.
The 75mm (3in) copper edge-wound voice
coil assembly is wound on a strong fiberglas former to improve force
transmission and power handling.
The already low distortion and
sound quality are further improved by Double Demodulating Rings (DDR)
that flatten impedance and phase with a constant power transfer.
A
special coating applied to both the top and back plates makes the
15ND930 far more resistant to the corrosive effects of salts and
oxidization.
