The mounting surface the AH speaker is being attached to should be able to handle five or more times the weight of the AH speaker (7x recommended for locations subject to high wind forces). Whenever the loudspeaker is mounted to a surface using the bracket, the installer must ensure that the surface is capable of safely and securely supporting the load. The hardware employed must be safely and securely attached both to the loudspeaker and the surface in question, using only the mounting holes. A general rule for soft surface installations (wood beams) is to multiply the corresponding working load limit by 75%: the result will be an approximate working load strength. Use thread locking compound for all installations. CAUTION: Mount the speaker such that the shear force is at a right angle to the mounting bolts, and close to the connection, as shown: SHEAR FORCE Lock Washer TENSION FORCE Flat Washer When mounting the AH speaker to a solid surface use the proper bolts, washers, and lock washers (Grade 5 minimum). Do not substitute mismatched bolts and washers. The AH speaker may be mounted to a pole or scoreboard. For such mounting, contact the light pole or scoreboard manufacturer for proper instructions. If mounting to another surface, such as a beam, see the diagram on page 7 for mounting hole locations. When in doubt contact a qualified structural/mechanical engineer for approval of the mounting materials and methods.

Note that the AH speaker mounting bracket allows the speaker to be tilted in excess of 50 degrees in either direction. See illustration below. 50° 50° Weep-holes (for drainage) (AH5040S, AH9040S, and AH6565S 15" models only) are located on the same side as the input connectors. If the speaker is tilted above parallel to the ground, the speaker should be installed with the weep holes down for water drainage.

The bracket may be removed from the speaker for installation convenience. When re-attaching speaker to bracket be sure to tightly secure speaker mounting bolts. Thread locking compound should also be used in this operation. 1. Choose the bracket mounting holes best suited for the surface you are mounting to. For best stability the 5.8" (16mm) diameter outer keyhole slots are recommended. 2. When using these mounting holes 1.2" (grade 5 hardware minimum) hardware should be used with proper flat and lock washers. Remember to use thread- locking compound ...
