MFR # 00560250 The Pro Rider driver series represents a new level of power and performance for Black Widow loudspeakers. These outstanding drivers have a power handling rating of 1,200 Watts program, along with high efficiency, reduced distortion and excellent overall sound quality. The series includes two 15” models in 8 Ohm impedance, suitable for both subwoofer and woofer applications.
The Pro Rider series uses a new cone that is a variation on the existing Kevlar impregnated cones used on all Black Widows. The new cone is stronger and tougher, highly water-resistant and has a specially designed deep roll accordion surround. The dust cap is also made of the same extremely strong material.
Voice coil assemblies on the new drivers use thermoset insulated aluminum or copper ribbon wire, edge wound and bonded onto an incredibly durable, heat resistant polyimide composite former. The coil wires are solderless diffusion welded to high conductivity OFHC copper foil leads which are embedded inside the former assembly and attached to the tinsel leads with high temperature silver solder. The solder joint is then coated with a special thermally conductive silicone adhesive for encapsulation and heat dissipation.
The voice coil assembly is bonded to the Kevlar cone and new super tough nylon composite spider using a thermoset epoxy originally developed for attaching nose cones on ICBM missiles – truly an aerospace grade adhesive. The spider and surround are bonded to the frame with a high strength adhesive.
The magnet structure includes subtle changes to its geometry that improve power handling. While it appears the same as the standard structure, and the replacement baskets from the Pro Rider series will fit on standard BW magnet structures, the improved power handling will be compromised if the standard structure is used.
The vent plate assembly used on Low Rider drivers to increase power handling is included in the Pro Rider series. This results in a significant improvement in power handling apabilities and long-term power compression.
These new drivers also adhere to the familiar features of Black Widow products: Cast aluminum frames, replaceable basket assemblies, Rubatex gaskets and highly reliable, spring loaded terminals are all used.
