The Morel CAW 428 is a 4 inch 8 ohm Woofer from the Classic Advanced range featuring the Morel Uniflow rigid steel chassis, Neodymium magnet system, 2.1 inch Hexatech voice coil and a shallow DPC (damped composite polymer) cone. The 8mm maximum linear excursion is high for a driver of this size.
The CAW range replace the legendary MW range.
