[. . . ] Not as efficient as a vented system, but it doesn't require a crossover for subwoofer use. 2. The new Low Rider 18" driver is a milestone in high-power subwoofer design. An incredible 1, 600 Watt program rating and extra-long cone excursion add up to amazing new levels of clean, deep bass. The Low Rider 18 is an superior choice for the bottom end of any high powered sound system, from DJ rigs to the largest professional touring shows. 3. DESIGN The Low Rider 18 utilizes a new cone that is a variation on the existing Kevlar®impregnated cones used on all Black Widow speakers. The new cone is stronger and tougher and uses an innovative asymmetrical-M surround for superior excursion and motion control. [. . . ] 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. These dynamic new drivers also utilize 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 extremely high power handling and available 1. 4" of cone travel combine for astonishing low frequency output, while the possibility of small enclosures adds a new dimension in compact, high output sound reinforcement systems. 4.

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 material 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. Take particular care in positioning of handles as subwoofers tend to be large and heavy. Do not use 1/4" phone plugs and jacks in the construction of your enclosures. Power capacity of the Low Rider 18 is well above safe limits for phone plugs and jacks. Neutrik® Speakon® connectors are highly recommended, and internal cabinet wiring should be at least 16 gauge stranded copper wire. Flying of subwoofers is not recommended. An array of subwoofer enclosures at ground level will typically outperform any other possible arrangement. 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. [. . . ] Other materials such as particle board and MDF are not acceptable. Use a quality wood glue, and fit joints tightly. Dado corner joints are highly recommended. Use wood screws or a pneumatic nailer to assemble the enclosure during gluing, to maximize joint strength. [. . . ]
