REPLACEMENT OF SPEAKER BASKET ASSEMBLY
1.Prior to replacement procedure, clean work area of all metal objects and other debris.
2.With speaker lying face down, remove the three screws on back of magnet structure with 7/16" nut driver.
3.. After screws are removed, lift the magnet structure off the basket frame.
4.Clean the voice coil “gap” before magnet structure is put on new replacement basket. (See illustration.) Fold a piece of masking tape over on itself several times, sticky side out, and insert it into the voice coil “gap.” Run it all the way around the “gap” several times to remove all particles of metal and other trash before magnet structure is put on new replacement basket.
5.Holding magnet structure in slanted position, gently lower the structure down into the basket so that it rests inside the magnet structure counter bore, being sure to align the screw holes, and lower the structure down into place. Insert screws and tighten.

INTRODUCTION
The 1508 and 1208 driver series represent a new level of power and performance for Black Widow loudspeakers. Power handling is increased by 40% over other comparable models, along with reduced distortion and higher overall sound quality.
The series includes 12" and 15" models in both 4 and 8 Ohm impedances.
DESIGN
The ’08 BWX 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 surround – a deep-roll accordion design on the 15", and an innovative asymmetrical-M style on the 12" that improves mid-range clarity. 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, 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 soldered 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 toughenedcyanoacrylate adhesive, which is also used to bond the dust cap to the cone.
The magnet structure includes subtle changes to its geometry that improve power handling. While it appears the same as the standard structure, and replacement baskets from the ’08 BWX series will fit on standard BW magnet structures, the improved power handling will be compromised if the standard structure is used.
These new drivers also adhere to the familiar features of Black Widow products: cast aluminum frames, replaceable basket assemblies, Rubatex gaskets and high reliability, spring-loaded terminals are all used.
APPLICATIONS
The 1508 and 1208 drivers are excellent choices for a wide range of sound reinforcement, high-level playback, subwoofer, and monitor applications.
The 1508sps driver is an excellent choice for general purpose sound reinforcement, and is available in both 4 and 8 Ohm versions. Enclosure size is reasonable and bass / mid-bass performance is strong. Its versatility includes sealed and bandpass enclosure designs.
The 1508cu produces amazing bass performance in small enclosures, along with flat mid-bass response for an accurate, clean sound quality.
