15-in diameter neodymium coaxial transducer designed for use in compact reflex enclosures and stage

96dB LF -108dB HF SPL 2.83v average sensitivity Dual neodymium magnet single motor 1200W LF - 260W HF maximum program power handling Smooth on/off axis 90 Degrees response 100 mm 4-in Interleaved Sandwich LF Voice coil ISV Aluminum Demodulating Ring SDR for minimum LF distortion 100 mm 4-in Edge-wound Aluminum ribbon HF voice coil EWAL HF pure titanium diaphragm HF copper sleeve for reduced distortion and higher output Smooth on/off axis 90 Degrees response Suitable for compact enclosures and stage monitorsThe LF cone provides smooth response within its intended frequency range thanks to its high damping pulp composition. Equipped with proprietary phase plug, the integrated 100mm 4'' HF compression driver has been designed to give smooth coherent wavefront in the horn entrance in all working frequency range and high level manufacturing consistency. The phase plug assures low distortion with remarkable improvements in mid-high frequency reproduction. A copper ring on the pole piece reduces the inductance figure of frequencies above 10 kHz, improving phase and impedance linearisation.The 4-in diameter HF diaphragm assembly uses a high strength, high temperature treated Nomex voice coil former joined directly to the titanium diaphragm on its upper bend edge, assuring extended frequency energy transfer. This improves linearity and shows unparalleled reliability when compared with a straight former joint.A specific HF exit profile design has been chosen in order to maximize the cone's profile coupling.The unique dual magnet single motor features high grade neodymium that makes the 15NCX1000 a lightweight speaker for its performance class.
