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.
DPC (Damped Polymer Composite) cone material
Large diameter Hexatech™aluminum voice coil
Copper insulated pole piece reduces inductance
Hybrid™neodymium/ferrite magnet
Uniflow™chassis removes air restrictions
