1. High magnetic permeability plates provide constant, even ux.
2. Neodymium magnet, for top SPL performance.
3. CCAR (Copper Clad Aluminium Ribbon) voice coil; for unheard-of thermal and
mechanical capability.
4. Extralight aluminium membrane.
5. Anodized aluminium body; for maximum damping and vibration rejection.
6. High current, screw terminals.
7. High efciency compression loading horn.
