This component is intended for installation in a suitable loudspeaker enclosure by a person with appropriate technical knowledge. It contains a powerful magnet, keep it away from pacemakers, implanted medical devices, credit cards, and magnetic storage media, and beware of pinch hazards when handling near ferrous metal or other magnetic drivers. Observe the rated power handling and impedance (see technical specifications); operation outside these ratings may cause overheating, distortion, or permanent driver failure. Connect and disconnect only with the amplifier switched off. Frame edges, terminals, and the surround may be sharp or delicate, handle with care during installation and avoid pressing on the cone or dust cap. Store and transport in a dry environment; moisture can damage the voice coil and suspension.
