2x Eighteen Sound 18NLW9400 18" Subwoofer Extended LF Neodymium Transducer 2400W

18 Sound 18NLW9400 18" Subwoofer 2400 Watts

Description

• The 18NLW9400 is a 18" (460 mm) extended low frequency loudspeaker, designed for use as a low bass or subwoofer component, in vented or bandpass configuration.

• The loudspeaker design provides clean and undistorted LF reproduction at a very high SPL and enables the transducer to withstand high power levels without damage. For optimum results we recommend amplifiers able to deliver 2400 Watt program power.

• The high grade neodymium magnet assembly is able to resist to the most demanding environmental operative conditions. 18NLW9400 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 100mm (4 in) copper round wire state-of-the-art voice coil, based on Interleaved Sandwich Voice coil (ISV) technology, provides high levels of thermal stability and durability.

• The ISV technology achieves a balanced linear motor unit exerting an exceptionally high force factor. This is realised through a high strength fiberglas former with half the coil wound half on the outside and half on the inside and bonded together using unique high-temperature resin adhesives. 18NLW9400 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.
