A fall from almost any height could result in serious injury or death. Assure that the speaker is firmly mounted to an object that can handle the weight of the AH speaker. Remember that wind will add considerable torque to the point of attachment. 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 INSTALLATION INSTRUCTIONSAH SERIES LOUDSPEAKERS 8", 12", AND 15" INSTALLATION VIA MOUNTING BRACKET (INCLUDED) General considerations and hardware recommendations CAUTION: AH series models weigh as much as 81 pounds (36.7kg) – model AH5040CD.

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.
