    • HF copper sleeve for reduced distortion and higher output
    • 80 degrees nominal conical dispersion
    • Suitable for very compact enclosures and stage monitor
    The 12NCX750 is a 12" neodymium coaxial transducer designed for use in compact reflex enclosures and stage monitors as small as 40 lt with a nominal dispersion of 80 degrees. The curvilinear profile LF cone provides smooth response within its intended frequency range thanks to its high damping pulp composition.The 75mm (3in) LF copper voice coil employs Interleaved Sandwich Voice coil (ISV) technology, in which a high strength former carries windings on both the outer and inner surfaces. This results in a balanced coil with a uniform distribution of mass and motive energy and an extremely linear motor assembly. The low distortion and sound quality are further improved by an aluminum demodulating ring (SDR technology) that flatten LF impedance and phase with constant power transfer.Equipped with proprietary hybrid radial tangerine phase plug, the integrated HF compression driver has been designed to give smooth coherent wavefront in the horn entrance in all working frequency range with an high level of manufacturing consistency. The phase plug, with its short openings and high flare rate value, assures low distortion and remarkable improvements in mid-high frequency reproduction. A copper sleeve reduces inductance value above 10 kHz, improving phase and impedance linearisation.
    The 2.4" 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 high force neodymium single magnet structure makes the 12NCX750 a lightweight speaker for its performance class - only 4,7 kg (10.36 lb). The XO12NCX dedicated passive crosssover filter is offered, making this neo coaxial speaker a ready-to-use transducer system. Due to the widespread use of high power audio systems at outdoor events, the ability to perform in adverse weather conditions is an additional key feature of the 12NCX750. This has been achieved using exclusive cone and magnet plate treatment processes which increase resistance against corrosion and make the cone water repellent.
