The 15NLW9401 is a 15" neodymium extended low frequency loudspeaker with 100mm (4in) diameter voice coil. It has been designed for use as a low bass or subwoofer component in either a more compact reflex, bandpass or horn loaded configuration. It provides clean, linear, undistorted low frequency reproduction at very high power levels. In its reflex configuration, it can be used in extremely compact enclosures (60 - 130 lt) with tuning frequency as low as 45 Hz. The high grade neodymium magnet assembly assures high flux concentration, low power compression and excellent heat exchange, resulting in high levels of force factor and power handling with an optimum power to weight ratio. The high excursion capabilities of the surround and suspension system, in conjunction with the Double Silicon Spider (DSS), enable the 15NLW9401 to achieve high levels of linear travel and maintain full control of the moving mass. The 15NLW9401 features a dedicated fiberglass reinforced water repellent treated cone, showing a high damping mode behaviour. The suspension system provides symmetric large signal characteristics throughout the whole working range, providing low harmonic distortion at different excitation levels. The 100mm (4in) 4-layers Interleaved Sandwich Voice coil (ISV) provides high levels of thermal stability and durability. The weight of the windings are evenly distributed, providing a uniform motive drive. This, in conjunction with the use of high temperature resistant adhesives, results in an extremely linear motor assembly. The 15NLW9401 ability to perform properly under inclement weather conditions has been achieved using a special coating applied to metal plates.
