Produktinformationen "Eighteensound 21NLW9001 4 Ohm"
The 21NLW9001 is an ultra low frequency 21 inch neodymium high
performance transducer. The transducer is the evolution of the 21NLW9000
subwoofer, and has been optimized for direct radiation and bandpass
subwoofer cabinet designs. For optimum results recommended amplifier
should be able to deliver 3600 Watt program power without clipping. At
the heart of the updated design stays the improved double silicon spider
based on DSS technology, letting the 21NLW9001 being able to control
the moving mass with high linearity, showing an exceptional stability of
mechanical parameter values in the long term. The transducer design
features include a high performance large displacement suspension system
for improved cone control at very high level of SPL matching. 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 copper voice coil is an
inside-outside split winding, four layers design, enabling the 21NLW9001
to handle up to 3600W program power. Bl force factor, as well as all
other electro-dynamic parameters, are linear within the working range.
The high excursion design (70mm before damage, ±14mm linear Xmax) makes
the The 21NLW9001 capable of amazing SPL in direct radiation enclosures
and its motor has been developed after intense FEA and fluidodynamics
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 low distortion and sound quality are
further improved by an aluminum demodulating ring (SDR technology) that
flatten impedance and phase with a constant power transfer. The carbon
fiber reinforced, straight ribbed cone shows a proprietary resin
treatment for extra pulp strength and water repellent properties. 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.
