15-in neodymium extended low frequency loudspeaker with 4-in diameter voice coil designed for use a

97 dB SPL 1W / 1m average sensitivity. 100 mm 4 in Interleaved Sandwich Voice coil ISV. 1200W AES power handling. Fiberglass reinforced water repellent treated cone. Double Silicon Spider DSS for improved excursion control and linearity. High grade neodymium magnet assembly. Improved heat dissipation via multiple back-plate vents. Ideal for 60 to 130 lt subwoofer cabinets Nominal Diameter: 380 mm in. Nominal Impedance: 4 O. Minimum Impedance: 3.8 O. Nominal Power Handling: 1200 W. Continuous Power Handling: 2400 W. Sensitivity: 397.5 dB. Frequency Range: 37 - 2300 Hz. Voice Coil Diameter: 100 mm 4.0 in. Winding Material: copperIt 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.
