7.4.3Using the Community WB1 Mounting Accessory

The WB1 mounting bracket kit consists of two steel brackets that can be attached to the mounting points for permanent attachment of the loudspeaker to architectural structures. Because of the angled sides on the enclosures, the WB1 will not mate flat to a surface behind the loudspeaker without bending the bracket. It is therefore recommended that the WB1 be used ONLY on the top and bottom of the enclosure. Refer to instructions packed with the WB1 for proper application and use.

7.4.4Stand Bracket Inserts (46 and 48 only)

For pole or stand mounting, XLT and XLTE models 46 and 48 have two 5/16-18 threaded inserts (T-nuts) on the bottom of the 46 and top of the 48. They are spaced 5.5 in. / 140 mm apart to mate with an Ultimate Support BMB- 200K stand bracket or similar hardware. Because of their size and weight, other XLT loudspeakers must be not be used for this type of mounting. For this reason, they do not have provisions for it. Community cannot provide specific technical support about the use of Ultimate Support or similar mounting products. For further information about such products see contact information in SECTION 4.9.

CAUTION:

Use stands and brackets only as instructed by the manufacturer. Misuse of such hardware can result in damage, injury, or death.

7.5XLTE MOUNTING/RIGGING POINTS (Except XLT41E and XLT48E)

(Refer to FIGURE 9 and FIGURE 10)

The XLTE loudspeakers have six captive 3/8-16 mounting/rigging points - three on the top and three on the bottom of the enclosures. These points are intended for mounting or suspending the loudspeaker using external hardware, such as the Community EYBLTKIT, appropriately rated for the purpose. The WLL (Working Load Limit) for each point is 150 lb. / 68 kg vertical pull and 60 lb. / 27.2 kg horizontal pull. The WLL for angles between the vertical and horizontal pull directions can be interpolated. See FIGURE 10 for the pull directions.

DANGER: (See FIGURE 10)

The retainer bolts permanently secure the mounting/rigging points to the enclosure. Do not try to unscrew, remove, or otherwise disturb any of these bolts. Doing so will damage the mounting/rigging points and make them unsafe to use for mounting or rigging the enclosure.
