Morel CAW 638 6" Cast Frame Woofer

The Classic Advanced line of woofers is based on Morel’s classic line - the renowned MW series. These products have high power handling due to the aerodynamic Uniflow™ open chassis and large diameter spiders. This woofer has reinforced ferrite magnets for the double magnet system delivering higher magnetic flux motor, resulting in a low resonance frequency and Qts points. Latest evolution of Morel's MW-164, MW-166, and MW-168 woofers.
