BRACKET INSTALLATION

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 supplied screw.

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 speaker’s 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.
