Morel ECW 638

Morel Elite Coppersleeve Series woofers feature large diameter voice coils, open yet strong frames, advanced composite cones, and carefully engineered magnetic circuits. A copper sleeve over the pole piece reduces inductance and extends high frequency response. Suitable for the most demanding audio reproduction systems.

• Large diameter Hexatech™aluminum voice coil
• Copper insulated pole piece reduces inductance
• Hybrid™neodymium/ferrite magnet
• Uniflow™chassis removes air restrictions
• High power handling
• High xmax
• Low Qts
