INDOOR/OUTDOOR LOUDSPEAKERS

WARNING: Mounting brackets must be secured in accordance with local codes. If in doubt, consult
a professional contractor to determine the integrity of the structure to which the bracket will be
attached. When required, a user-supplied safety strap can be secured to the back of the speaker
cabinet using the threaded brass insert and the forged steel safety bolt (included).

MULTIPLE SPEAKERS AND SOUND COVERAGE

Placement is critical when the goal is smooth, even sound coverage of an area. Horizontal and
vertical dispersion usually vary with 2-way speakers, so installation orientation should be consistent.
Models A6 and A8 deliver about 110 and 100 degrees of horizontal sound coverage, respectively,
while the coaxial A2 provides about 90 degrees. Too great a distance between any 2 speakers will
create a dead spot in the coverage. When in doubt, use more speakers to ensure adequate coverage.

OTHER FACTORS TO CONSIDER

Distance is not the only factor affecting sound intensity. Others that should be considered in the
planning phase are adjacent surface reinforcement and environmental effects such as temperature
extremes and humidity (mainly in outdoor installations).

LOW FREQUENCY OUTPUT

Bass output level depends on a speakerʼs location. The more reflecting surfaces in proximity to the
speakers (walls, ceilings, floors), the greater the bass output. Therefore, speakers mounted in free
space (e.g., hanging from an overhead support) will produce comparatively less bass output.

UNDERPOWERING VS. OVERPOWERING

Most speaker damage is caused by amplifiers with too little power. An overdriven amp sends
clipping distortion to the speakers. Clipping is usually audible; it may vary from a harsh sound to a
fuzzy or blurry sound. If you hear clipping at loud volume levels, turn down the volume until the
distortion is no longer present. Damage caused by operating the speakers at distorted volume
levels is not covered by the warranty.

PAINTING

The speaker cabinet and grille can be painted with a thin coat of spray paint. Remove the grille and
mask the speaker assembly so that only the cabinet gets painted. Then, if desired, spray the grille
lightly to avoid plugging the holes.

MAINTENANCE

None required. Speaker cabinets can be wiped clean with a soft, damp cloth.
