Mounting
CAUTION:
Mounting the AH loudspeaker requires two people, unless it is possible to safely clamp the
speaker in position for alignment before mounting.
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 fl
at and lock washers. Remember to use thread- locking compound on all parts.
3. Use the dimensions noted on the illustration to mark the points where the starting hole should be
drilled.
4. Choose appropriately sized bit and drill holes.
5.
Attach speaker bracket, using bolt, fl
at washer, and lock washer as shown and re-attach
loudspeaker to bracket.
6. Secondary (safety) suspension point: Use a load rated cable or steel chain (capable of holding
the speaker should it come loose from the primary mounting point). This cable or chain assembly
should be attached to at least (2) of the drop forge eyebolts provided on the AH speaker and
secured to the mounting surface via approved, load rated hardware.
