There are two pieces of rear rigging hardware and two pieces of front rigging hardware required for this purpose. The front hardware consists of two Xvsg chain assemblies. Two types of rigging hardware may be used at the rear - either two Xvhg flexible-chain grid hinges or two Xvhl solid-arm linking hinges. [. . . ] Two types of rigging hardware may be used at the rear - either two Xvhg flexible-chain grid hinges or two Xvhl solid-arm linking hinges. Xvhg chain grid hinges allow a flexible attachment to the grid. This makes attachment to the grid faster; however, the grid cannot ride on top of the loudspeakers during transportation. Xvhl solidarm linking hinges allow a rigid attachment to the grid. This makes attachment to the grid a bit slower; however, the height is less and the grid may now ride on top of the loudspeakers during transportation. The Xvhg offers a higher rigging strength when the top box is angled down more than 20 degrees, while the Xvhl offers greater rigging strength when the top box is angled down less than 20 degrees. (Note that the Xvhl linking hinge is the same hardware used to link two enclosures together. ) This hardware will work for attaching any of the loudspeaker systems to the grid. The selection of whether to use the Xvhg or Xvhl for the rear rigging hardware is left to the customer. Linking One Loudspeaker to Another: The second set of rigging is used to link two enclosures together. Again there are two pieces of rear rigging hardware and two pieces of front rigigng hardware required for this purpose. The Bottom Stacking Dolly will not work with the trapezoidal Xvlt. The Downfill Stacking Dolly may be used to transport two Xvlt and one Xfil1/Xfil2 enclosures. This dolly also makes moving in and out of a venue quick and easy because two Xvlt enclosures and one Xfil1/Xfil2 enclosure can be stacked and transported on a single dolly with all of the rigging hardware attached. The Bottom Stacking Dolly will not work with the rectangular Xvls or Xsub. The Front Dolly secures to the front of a single enclosure and may be used on the Xvls, Xvlt or Xsub enclosures. One Front Dolly is required for each enclosure and the rigging hardware cannot remain attached to the enclosure when riding on the dolly. Although the Front Dolly requires more effort, it offers maximum protection for the front of the loudspeaker and allows the loudspeakers to be manually lifted and carried if necessary. Most customers will typically use the Bottom Stacking Dollies for all of their Xvls and Xsub enclosures, and the Front Dolly for the Xvlt enclosures. Customers with large systems may prefer the Downfill Stacking Dolly. There is not an individual dolly for the Xfil1/Xfil2 loudspeakers at this time. [. . . ] Customers with large systems may prefer the Downfill Stacking Dolly. There is not an individual dolly for the Xfil1/Xfil2 loudspeakers at this time. Telex/EV does not manufacture or sell dollies; however, the EV/Telex engineers have worked with R&R Cases (a thirdparty company which specializes in cases and hardware for the professional loudspeaker industry) to develop dollies for the X-Line loudspeakers that R&R will sell direct to our customers. The recommended digital electronic controller for use with the X-Line loudspeakers is the KlarkTeknik DN9848, which is available through the normal KT/Telex distribution. [. . . ]
