Compared to our industry standard 18LW1400, the 18LW9400 provides higher maximum SPL, increased program power handling and lower power compression. For optimum results we recommend amplifiers able to deliver 2400 Watt program power without clipping. Transducer design features include a large displacement suspension system which, in conjunction with a fiberglass reinforced, straight ribbed cone and the Eighteen Sound proprietary Double Silicon Spider (DSS) technology, allows an ultra-linear piston action and provides full mechanical control across the entire working range. The 100 mm (4 in) inside-outside copper voice coil based on Interleaved Sandwich Voice coil (ISV) technology provides high levels of thermal stability and durability. In order to furtherly increase power handling and reduce power compression figure, 18NLW9400 uses the same voice coil ventilation technology developed for our flagship 9000 neodymium transducer series. A special low density 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.18LW9400 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. In addition, the special treatment applied to top and back plates of the magnetic structure is far more resistant to the corrosive effects of salts and oxidization.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eEighteen Sound 18NLW9400 8 Ohm 18″ 1200W Loudspeaker\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ch4\u003e\u003cstrong\u003eGeneral Specifications: \u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eNominal Diameter 18”, 460 mm\u003c\/li\u003e\n\u003cli\u003eRated Impedance 8Ω\u003c\/li\u003e\n\u003cli\u003eAES Power 1200 W (rms)\u003c\/li\u003e\n\u003cli\u003eProgram Power 2400 W (rms)\u003c\/li\u003e\n\u003cli\u003ePeak Power 7000 W (rms)\u003c\/li\u003e\n\u003cli\u003eSensitivity 98 dB\u003c\/li\u003e\n\u003cli\u003eFrequency Range 30 – 2500 Hz\u003c\/li\u003e\n\u003cli\u003ePower Compression @-10 dB 0,7 dB\u003c\/li\u003e\n\u003cli\u003ePower Compression @-3 dB 1,5 dB\u003c\/li\u003e\n\u003cli\u003ePower Compression @Full Power 2,2 dB\u003c\/li\u003e\n\u003cli\u003eMax Recomm.
