GROUND INSTALLATION

General considerations and hardware recommendations
Excellent results may be achieved by mounting the AHSUB15-BSG under bleacher seating. Electronic
delay is suggested to approximate time alignment of full range speakers with subwoofer(s) to the listener
locations.
CAUTION: The AHSUB15-BSG weighs 181 pounds (82.1kg). 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.
For on ground installation a 36" square 2" thick (minimum) concrete pad is suggested. If this pad is to be
poured concrete, rebar anchors are suggested to allow chain or cable securing of the AHSUB15-BSG for
theft resistance.
Overhead Suspension Installation
Remember that wind will add considerable torque to the point of attachment. The mounting surface the
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).
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. 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.
