Professional 8 ohm speaker 18NLW9400

The 18NLW9400 is an 18-inch extended range low-frequency speaker designed for high-SPL subwoofer applications in reflex, band-pass or horn-loaded configurations. For best results we recommend amplifiers that can deliver 2400 Watt program power without clipping. Transducer design features include a large displacement suspension system which, in combination with a ribbed, fiberglass-reinforced rigid cone and Eighteen Sound's proprietary Double Silicon Spider (DSS) technology, enables ultra piston action. - Linear and provides full mechanical control during the entire range work. The 100 mm (4 inch) internal-external copper voice coil based on ISV (Interleaved Sandwich Voice Coil) technology provides high levels of thermal stability and durability. To further increase power handling and reduce power compression, the 18NLW2400 utilizes the same voice coil ventilation technology developed for our flagship 9000 neodymium transducer series. A special low-density material air diffractor has been placed in the rear plate which acts as a cooling system, increasing the power handling capacity and lowering the power compression value. As a final result Eighteen sound engineers achieved a nearly 1 dB reduction in full power compression value compared to 18LW1400, and an increase in the program's power handling value of 2400 Watts. 18NLW9400 is able to function properly in adverse weather conditions: the unique cone treatment improves pulp strength and gives water repellent properties to both sides of the cone.
