General Description
The 18NLW9600 is an extended low frequency 18 inch neodymium
high performance transducer. The loudspeaker has been designed
for use as a subwoofer component, in either a reflex, bandpass or
horn loaded configuration, in high power auditorium or arena
loudspeaker systems.
For optimum results recommended amplifier should be able to
deliver 3600 Watt program power without clipping.
Eighteen Sound engineers have obtained the best possible results
with today's available materials in terms of clean and undistorted
LF reproduction at a ultra high SPL, with the lowest possible power
compression figure.
The transducer design features include a large displacement
suspension system specifically designed for matching the carbon
fiber reinforced, straight ribbed cone.
Thanks to the Triple Silicon Spider (TSS) technology, the 18NLW9600
is able to control the moving mass with high linearity, showing an
exceptional stability of mechanical parameter values in the long
term. Bl force factor, as well as all other electro-dynamic
parameters, are linear within the working range. This, together with
the exceptional high excursion behavior - 70mm before damage,
±14mm linear Xmax - makes the 18NLW9600 an extremely low
distortion, highly dynamic transducer.
The state-of-the-art 5,3" inside outside ISV (Interleaved Sandwich
Voice Coil) aluminum voice coil enables the 18NLW9600 to handle
3600W program power value.
The 18NLW9600 has been developed after intense FEA and
fluidodynamics simulation and testing, focusing on dissipating the
heat generated by the powerful voice coil. Special attention was
given to the optimization of air flow into the gap without introducing
audible noise. A special low-density material air diffractor placed
into the heatsink acts as a cooling system, increasing the power
handling capability and lowering the power compression figure.
The exclusive cone treatment improves pulp strength and gives
water repellent properties to both sides of the cone. A special
coating applied to both the top and back plates makes the
transducer far more resistant to the corrosive effects of salts and
oxidization.
