The 18NLW9000 is an 18 inch neodymium high performance subwoofer. The loudspeaker has been directly derived from our flagship 18NLW9600, and has been optimized for vented and bandpass subwoofer cabinet 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.
Thanks to the Double Silicon Spider (DSS) technology, the 18NLW9000 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 18NLW9000 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 18NLW9000 to handle 3600W program power value.
The 18NLW9000 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 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.
18NLW9000 is able to perform properly under inclement weather conditions: 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.
