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
state-of-the-art 5,3″ diameter ISV CCAW (copper clad aluminum wire)
voice coil shows a inside-outside split winding, four layers design,
enabling the 18NLW9600 to handle up to 3600W program power.
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 already low distortion
and sound quality are further improved by an aluminum Single
Demodulating Ring (SDR technology) that flatten impedance and phase
with a constant power transfer.
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.
