A
second
consideration is for feedback and bass
performance. If the speaker is placed near a large, flat
wall, the bass output will be increased by approximately
6 dB. Placing the speaker near a wall can cause
feedback. If this occurs, the speaker must be moved.
In general, placing speakers near a wall works best if
the sources feeding the speaker are line level items.
A
third
consideration is to what degree the speaker
should be "heard and not seen", especially in
permanent installations. Flying (hanging the speakers
from the ceiling) is one option whereby the 2912 / 2915
can be integrated with a 118s subwoofer. In this
configuration, the speakers can be arranged in any
array of up to three rows (tiers), loose or tight pack,
with or without downward angling (splaying).
The Fender RigSafe
™
system is designed into both
speaker cabinets models to safely accommodate such
practices. This system is compatible with both the JBL
S.A.F.E.
™
and the ATM Flyware
™
rigging systems.
Nonetheless, flying loudspeakers above crowds is
dangerous and should only be undertaken by
experienced and insured riggers. For more information
on safe rigging practices, please refer to the "Flying
with Fender RigSafe
™
" brochure (p/n 049646) or
contact ATM FlyWare at (310) 834-5914.
To change the dispersion pattern from 90º to 60º, first
remove the grille from the speaker. Using a small screw
driver, gently pry the grille away from the top and
bottom cleat. Next, gently pull outward at the center
of the grille; it should bend and pull out from under the
sides. If your insert has a plug on it, you may wish to
remove it for easier installation. To do so,
carefully
cut it off with a razor blade. To attach the two horn
inserts, first place the wider end of the insert under the
front lip of the horn. Next, guide the smaller end of the
insert under the ribs near the throat of the horn. The
insert is secured in place by the 3 ridges.
Reinstall the grille by placing one side of the grille under
the side cleat, then gripping the grille on the top and
bottom, bend the other end under the cleat at the
opposite end of the cabinet. With the inserts installed,
the horizontal coverage angle is reduced to 60º.
The
high frequency driver
for all enclosures is a
compression driver using high technology polymer
materials to handle large amounts of power. This
compression driver is mated to an innovative
Controlled Dispersion
™
horn that allows a single horn
to be used for a number of applications. The quick
placement or removal of the horn inserts can change
the horizontal coverage pattern from 60º to 90º. When
both inserts are installed, a 60º coverage pattern is
achieved. This is useful in multi-cabinet tight pack
arrays where a narrower consistent coverage pattern
is required. With the horn inserts removed, a 90º
coverage pattern is attained offering a wider horizontal
dispersion pattern.
