EAW AX Series & CSA Technology (c2004)
The AX Series
The new AX series uses a newly-designed MF/HF coaxial transducer, loaded onto a common horn via the phase plug described above. The coaxial transducer is composed of a high efficiency 2.5-inch voice coil, 8-inch cone midrange in a sealed chassis and a 2.5-inch voice coil, 1.4-inch exit compression driver. The midrange and compression driver share a common neodymium magnet, significantly reducing weight. This common magnet also allows us to minimize the distance between the voice coils of the MF and HF devices, and by extension their acoustic origins. The sealed midrange chassis is made of aluminum and acts as a heat sink for the entire assembly. The exit of the mid frequency phase plug is just over 4 inches in diameter, allowing wider coverage angles at the upper range of the mid frequencies.
