The Classic Advanced CAW 428 is based on Morel's renowned MW series. These products have high power handling due to the aerodynamic Uniflow™ open chassis and large diameter spider. This woofer has reinforced ferrite magnets for the double magnet system, delivering higher magnetic flux and resulting in a low resonance frequency and Qts point.
75mm large Hexatech™ aluminum voice coil
Uniflow™ steel chassis
High flux ferrite double magnet system
Shallow profile DPC cone
High excursion
