The Peavey BWX Series 1203-8 Super Structure Black Widow Loudspeaker features Kevlar impregnated cones and a high-efficiency magnet structure to provide impressive sensitivity, reliability, and performance. The Kevlar impregnated cone is stiff, reducing its tendency to distort the shape of the voice coil, thus avoiding rubs and scrapes. You enjoy great power handling results from this 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.

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.
