Description
The 21NLW9600 is a 21 inch neodymium high
performance transducer. The transducer is suitable
for high loading, ultra-low frequency horn loaded or
bandpass subwoofer designs.
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.
The state-of-the-art 135 mm (5,3 in) ISV inside
outside copper voice coil enables the 21NLW9600 to
handle 3600 W program power value.
Thanks to the Triple Silicon Spider (TSS)
technology, the 21NLW9600 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
electro-dynamic parameters of 21NLW9600 are linear
within the working range. This, together with the
high excursion behavior - 70 mm before damage, ±14
mm linear Xmax - makes the 21NLW9600 an extremely
low distortion, highly dynamic transducer.
The 21NLW9600 has been developed after intense FEA
and fluido-dynamics simulation and testing, focusing
on dissipating the heat generated by the powerful
5.3" 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 backplate
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 straight ribbed 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 |
