Description

The 15NW530 low frequency neodymium transducer has been specifically
developed for high power, low distortion, compact subwoofer
applications.
The
transducer finds its main application on compact vented subwoofers as
small as 75 lit. properly tuned, but it is suitable also in bandpass or
horn loaded applications.
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 transducer incorporates Eighteen Sound exclusive
DSS technology (Double Silicon Spider) in combination with a single
roll highly damped rubber surround.
The already low distortion and
sound quality are further improved by properly positioned Single
Demodulating Ring (SDR technology) that flatten impedance and phase
with a constant power transfer.
The 75mm edge-wound state-of-the-art
voice coil assembly is wound on a strong fiberglas former to improve
force transmission and power handling.
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
in-house developed cone treatment is a humidity repellent and
significantly dampens bell mode resonances.
A special coating
applied to both the top and back plates makes the 15NW530 far more
resistant to the corrosive effects of salts and oxidization.
