7.5.1Using the Community EYBLTKIT

The Community EYBLTKIT has four drop-forged, load-rated, 3/8-16 eyebolts with locking washers. They are designed for use in the mounting/rigging points on the XLTE loudspeakers. Refer to the instructions that are included with the EYBLTKIT accessory for proper use.

7.6STACKING ENCLOSURES

XLT and XLTE enclosures may be temporarily stacked to provide greater height. This is particularly useful when stacking a full-range loudspeaker on top of a subwoofer. This can put the full-range loudspeaker at or above the audience’s ear level to provide greater projection of sound to the rear of the audience. Both the XLT and XLTE enclosures have provisions to help prevent the top enclosure from moving around due to sound vibrations or from sliding off if accidentally bumped.

CAUTION:

Stack enclosures only on level, solid surfaces, so that the stack will not sit at an angle and is stable. Ensure the top enclosure will not shift position and possibly fall off. Locate the stack where it will not be bumped nor knocked over. Do not stack more than two enclosures high. Failure to observe these guidelines can result in damage, injury, or death.

7.6.1Stacking XLT Enclosures (XLT43, XLT46, XLT47, and XLT55)

The XLT enclosures have corner protectors with integral ridges that are designed to nest into one another when stacking two XLT enclosures of the same width and depth. When the enclosures are aligned side-to-side and front-to- back, the ridges on the corner protectors will line up to help link the enclosures together.

7.6.2Stacking XLTE Enclosures (XLT43E, XLT46E, XLT47E, and XLT55E)

The XLTE enclosures have four heavy-duty rubber feet that facilitate stacking. The XLT55E subwoofer has four recesses in its top. They are located so that the four feet of another XLTE enclosure of the same width and depth will nest into them when the enclosures are aligned side-to-side and front-to-back. If stacking two full-range enclosures, carefully align the enclosures side-to-side and front-to-back so that all four feet on the top enclosure are completely on the lower enclosure. The rubber feet on the top enclosure provide friction to help keep it in place.
