The 18W2000 is a low frequency woofer which sets a benchmark in 18" (460 mm) high output transducers. Showing 20% higher power handling and 10% lower weight, it represents a significative development of the acclaimed 18W1000 model. The 18W2000 can be used as a low bass or subwoofer component in either a reflex, bandpass or horn loaded configuration. It provides clean, linear, undistorted low frequency reproduction at very high power levels. The high excursion capabilities of the surround and suspension system, in conjunction with the Double Silicon Spider (DSS), enable the 18W2000 to achieve high levels of linear travel while maintaining full control of the moving mass. The high quality curvilinear cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress. The 100mm diameter copper wire voice coil employs the Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a balanced coil with a uniform distribution of mass and motive energy. This results in an extremely linear motor assembly. Maximum flux concentration and force factor in the gap is assured by the unique shape and design of the top and back plates, which have been researched and designed using our in-house magnetic flux FEA CAD resource. 18W2000 uses the voice coil ventilation technology developed for our flagship 9000 neodymium transducer series. A special low density multi-cell material air diffractor has been placed into the backplate acting as a cooling system, increasing power handling capability and lowering the power compression figure. As a final result Eighteen Sound engineers obtained almost 1 dB reduction in full power power compression value if compared to 18LW1400, and an increased program power handling value of 2400 Watt. 18W2000 is able to perform in adverse weather conditions or in areas of high humidity. This key feature has been achieved using an exclusive water repellent cone treatment and magnetic plate coating which resists against environmental corrosion.
