Morel EM 428D

Morel EM 428 incorporates a damped polymer composite cone, 54mm Hexatech™ aluminum voice coil, neodymium magnet system, high power handling, and a smooth response up to 5kHz. These features combine to produce a very impressive midrange driver. Improved version of Morel's famous MW 114S.
