The Peavey BWX SC NEO, patent pending, woofers are a milestone in high-power design. An incredible 1300 watts program, 2600 watts peak power rating and extra-long cone excursion add up to an amazing new power level. This lightweight Neodymium Black Widow® woofer features a 4” voice coil and neodymium magnet structure making these woofers a superior choice for any high powered sound system, from DJ rigs to the largest professional touring shows.

DESIGNBWX SC NEO woofers utilize a high density Kevlar®-impregnated cone as used on all Black Widow speakers. The cone is stronger, tougher and highly water resistant. High quality spring terminals accepting large gauge wire are attached to large diameter, high current tinsel leads with silver solder to withstand high current, high temperatures and long excursion.

The voice coil uses polyimide-insulated aluminum ribbon wire, edge-wound and bonded onto an incredibly durable and heat resistant polyimide composite former The coil wires are solderless diffusion welded to high-conductivity OFHC copper ribbon 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 adhesive for encapsulation and heat dissipation. The voice coil assembly is bonded to the cone and new incredibly tough, plastiseal-coated Nomex progressive-roll spider using a high temperature thermoset epoxy.

The patent pending magnet structure design was developed using extensive finite element computer modeling. The magnet structure is

encapsulated within the newly designed die cast aluminum heat sink using the highest quality of ultra-low carbon steel available. The result is a 30% increase in power handling over our standard Black Widow Super Structure magnet assembly. Increasing the power handling from 1000 watts program to over 1300 watts program.The new heat sink venting method adds additional cooling for the voice coil. This thermally conductive, ported and finned aluminum heat sink delivers cool air pumped by the spider and dust cap directly to the voice coil to keep operating temperatures under control. The improved cooling increases power handling, reliability and reduces power compression. The cast aluminum frame is tough and rigid, with the strength needed to hold the cone and magnet in perfect alignment. The deep dish design and large spider clearance make high excursion and high output possible. This dynamic new driver utilizes the user-friendly Black Widow replaceable basket assemblies with Rubatex® gaskets.The result of all these specially designed components is a loudspeaker that is truly amazing. The BWX SC NEO woofers with extreme high power handling and efficiency adds a new dimension in high output sound reinforcement systems.APPLICATIONThe BWX SC10, 10” woofer, is the excellent choice for a wide range of sound reinforcement, high-level playback, and monitor applications. It works well in a sealed or vented full range enclosure. Enclosure volume requirement is minimal, allowing for extremely small designs. The best application in compact enclosure includes monitors, sound reinforcement, bass guitar and keyboard enclosures.The BWX SC12, 12” woofer, is the excellent choice for a wide range of sound reinforcement, high-level playback, and monitor applications. It works well in a sealed or vented full range enclosure. It has a smooth, extended frequency response. The best application is in compact enclosure for very high quality mid bass/mid range reproduction.

The BWX SC15, 15” woofer, is the excellent choice for a wide range of sound reinforcement, high-level playback, and monitor applications. It is best used on the bottom end of a full range enclosure. It has very high efficiency for superior output in the mid bass and mid range.The BWX SC18 , 18” woofer, is the excellent choice for a wide range of sound reinforcement, high-level playback, and monitor applications. Enclosure size is reasonable and Low-bass performance is strong. Vented and properly designed dual-reflex bandpass enclosures are also suitable for this driver.ENCLOSURESTo assist with the growing interest in home-built enclosure designs, Peavey provides complete parameter data on these drivers as well as several recemmended enclosures for each model. This information and much more can be found at www.peavey.com.Use a quality wood glue, fit joints tightly, and add internal bracing to stiffen the panels of the enclosure. Look at comercially designed enclosures for ideas on good brace placement. Use wood screws or a pneumatic nailer to assemble the enclosure during gluing, to maximize joint strength.Strength of the completed enclosure has a great effect on the bass performance of the finished system. Box panels that aren’t stiff enough will vibrate—cancelling bass produced by the woofer, and creating undesired sounds of their own. If your box vibrates or you don’t think the box panels are stiff enough, add more bracing.Vents used in the examples require standard Schedule 40 PVC pipe for vent construction. The pipe should be dadoed tightly into the back of the baffle and glued firmly in place with high quality epoxy or high strength industrial grade hot glue. Rough up the outside of the pipe to improve the glue bond.Be sure to account for the displacement of the vent, bracing, horn (if used) and woofer for your enclosure before building it, or it will be smaller than its intended volume. This can reduce bass output and mis-tune the enclosure.

Line the inside of the enclosure with polyester fiber batting such as quilt stuffing. The batting material should conform to California bedding fire codes. Attach the batting with spray adhesive or staples, and keep it away from the end of the vent tube where it could be pulled in by air flow. Handles, protective corners, cabinet covering, grille materials and crossovers are available through Peavey Accessories.When building a bandpass enclosure, design a panel or door to be removable for access to the woofer. Use foam weather-strip to seal the panel along with enough screws and bracing to prevent leaks and buzzes. Fill the sealed volume loosely with polyester fiber, but leave the vented volume empty. Place the magnet of the woofer in the vented side for improved cooling.Peavey does not supply hardware required for the manufacturing of flying systems, and recommends that builders should not suspend or fly any enclosure not certified for such applications.These instructions are a general guideline for design. Proper construction techniques, good planning and common sense will result in a reliable, high quality, high performance system. Peavey in no way accepts liability for any damage, accidents or injury that may result from construction or use of enclosures using this information.Features and specifications are subject to change without notice.PARAMETERSThiele-Small parameters for BWX NEO drivers follow.
