The 12CX1 is a 12" / 1" coaxial transducer designed for use in compact reflex enclosures and stage monitors with a nominal dispersion of 80 degrees.

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 65 mm (2.5 in) LF voice coil has Kapton former, which together with high temperature resistant resin ensure high reliability by high power.A triple aluminium demodulating rings on the magnet structure reduce distortion and inductance and improve transient response.

The 1" exit compression driver adopted is our D2544 model. The HF driver diaphragm assembly, using triple layer polyester dome this together with phasing plug improve linearity of frequency response in high end. The top and back plates are treated with special high quality epoxy electro-deposition coating, which extremely improves the corrosion resistance of the speaker.

Because of design with single magnet assembly the speaker has light weight and compact size.
