[. . . ] Xf X-ArrayTM Two-Way, MB/HF System · Unprecedented acoustic output in small, lightweight package · Ring-Mode Decoupling (RMDTM) provides accurate transient detail · Neodymium ND5 HF and MB drivers · Unique rear-hinge rigging · Enclosure shell and rigging identical to all of the full-size X-ArrayTM systems · Far-field, 40° x 20° coverage pattern Description The X-ArrayTM product line represents important advancements in concert-sound-reinforcement technology. The design goals called for the highest-acoustic output capability with the highest fidelity in lightweight, compact enclosures that were easy to array. The development began with a clean sheet of paper and took an integrated approach. The individual loudspeaker drivers, horns, enclosures, rigging hardware and system configurations were designed from the ground up specifically for this high-performance application. [. . . ] Thus, different systems may be mixed in an array to achieve the best acoustic results. The rigging system allows for the smallest possible spacing between adjacent enclosures, and utilizes quick-release rigging fittings for fast installation and tear down. When flown, the X-ArrayTM enclosures are linked together by two removable hinges on the rear of the enclosures at the top and bottom. This arrangement enables the enclosures to pivot vertically from the rear corners. The relative vertical angle between adjacent enclosures is adjustable and set by two removable rigging straps on the front of the enclosures at the top and bottom. Both the rear rigging hinges and the front rigging straps are installed when enclosures are sitting on top of one another. For ease of installation of the hinges and straps, the enclosures self align using feet and cups mounted on the top and bottom of the enclosures. The relative horizontal angle between adjacent columns of loudspeakers is set by adjustable grids at the top of the array (or by custom-building attachment supports in permanent-installation applications where grids are not used). The removable proprietary rear rigging hinges utilize all-steel construction and are secured into a proprietary track assembly on the enclosure (similar to the heavy-duty aircraft L-track). The aluminum track is extruded as a single-piece track/angle-bracket assembly and ties into the top, bottom and rear of the enclosure. In the event of failure, the diaphragm assembly can be replaced with the driver attached to the horn. MB: Remove the screws securing the hatch on the back of the enclosure, and lift the hatch out. Remove the screws securing the 12-inch driver and lift the driver out of the enclosure. In the event of failure, the entire driver must be replaced or reconed. The following service parts are available from the service department in Buchanan, MI USA: HF: #84233-XX 16-ohm ND5-16 diaphragm kit #827-2973 ND5-16 complete driver MB: #812-2858 ND12A complete driver. The complete drivers are available only for repair replacement and are not available for general sale.
