The Peavey 1801-4 Black Widow Super Structure Speaker features Kevlar impregnated cones and a high-efficiency magnet structure to provide impressive sensitivity, reliability, and performance. The Kevlar impregnated cone is stiff, reducing a tendency of the cone to distort the shape of the voice coil, thus avoiding rubs and scrapes. You enjoy great power handling results from the increased stiffness, especially with large cone excursions. This cone also offers low distortion due to dampening of unwanted cone vibrations. The piston action of the Kevlar impregnated cone is extended to a higher-frequency, while the range above is better controlled, with a reduction in vibrational breakup.

The magnet structure features a patented technology - a single piece die-cast back plate/pole piece assembly. This construction eliminates an undesirable air gap in the magnet circuit, enhancing efficiency and reliability.

In the unlikely event of failure of the Black Widow loudspeaker, the cone/basket assembly is field replaceable with a factory assembled and tested replacement basket assembly. So, instead of having to obtain a whole new speaker, only a new basket assembly is required. The lightweight replaceable basket assembly offers an easy solution to spares and repairs. These replaceable baskets eliminate the need for re-coning speakers and the frustration and delays associated with the re-coning process. It only takes a few minutes to replace a basket and you are back in business.

The Black Widow Speaker features a 4” edge wound aluminum ribbon voice coil wound on a space-age polyimide composite former for high efficiency and sensitivity, a die-cast aluminum alloy frame for exacting lifelong alignment of the assembly, an extra large vent in the magnet structure for superior cooling and linearity at high-drive levels, and heavy-duty spring-loaded terminals adhering to industry standards for color coding.
