The 12H4CX72 is a 12" / 1.4" coaxial transducer designed for use in compact reflex enclosures and stage monitors with a nominal dispersion 60 degrees conical.
The low profile, smooth curvilinear LF cone provides smooth response within its intended frequency range and water prove protective coating, allowing application in a wide range of environments. The state-of-the-art extreme light 100 mm (4 in) LF voice coil ensure low Mms which gives perfect voice reproduction.
The aluminium demodulating ring in the magnet structure reduces distortion and inductance and together with copper plated pole piece and top plate improve transient response. The neodymium 1.4" exit compression driver adopted is our ND72HB model.
The HF driver diaphragm assembly, using hybrid dome this together with phasing plug improve linearity of frequency response in high end. The double magnetic structure allow to get maximum performance. The HF part of magnet structure has cooper ring on the pole piece, which reduces the inductance figure of frequencies above 10 kHz, improving phase and impedance linearisation. This ensures extremely high SPL in the high end of the frequency response.
