Speaker - Peavey, 15", Black Widow 1505-8 DT BW, 700W, 8Ω
The 1505DT is an 8 ohm, 15" Black Widow/Super Structure speaker with a curvilinear cone for extended bandwidth. Offering a rare combination of usable frequency response into the mid-range with a smooth powerful low end, the 1505DT, Kevlar cone and long voice coil provide excellent linearity at high drive levels. Excellent as a woofer in multi-way enclosures or as the bottom end in a two-way system.
These state-of the-art speakers feature Kevlar® impregnated cones and a high efficiency magnet structure to provide outstanding sensitivity, reliability, and performance. The Kevlar impregnated cone is stiffer than an equivalent weight paper cone, reducing the tendency of the cone to distort the shape of the voice coil, thus avoiding rubs and scrapes. Superior power handling results from the increased stiffness, especially with large cone excursions. This cone also offers lower distortion than a paper cone due to a greater 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 break-up.
The magnet structure features a patented Peavey technology: a one piece die-cast back plate/pole piece assembly. This construction eliminates an undesirable "air gap" in the magnet circuit, enhancing efficiency and reliability.
Another Peavey original is the design of the speaker framework. In the unlikely event of the failure of a Black Widow loudspeaker, the cone/basket assembly is field replaceable with a factory assembled and tested replacement basket assembly. Instead of being forced to obtain a whole new speaker, only a new basket assembly is required. Lightweight and relatively inexpensive, the replaceable basket assembly offers an easy solution to spares and repairs.
Along with these state-of-the-art aspects, Black Widow speakers also provide the features expected in a professional application loudspeaker: a four inch edgewound aluminum ribbon voice coil wound on a Kapton(TM) 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.
