INTRODUCTION  
Thank you for purchasing a Tour Series 2912(c) /  
2915(c) Loudspeaker System from Fender® Pro Audio.  
We are sure you will find it both a unique and effective  
sound reinforcement product, providing years of  
trouble-free service.

The 2912(c) /2915(c) is a professional, full-range, two-  
way, compact loudspeaker designed for the most  
demanding concert sound and sound contracting  
requirements. With a scientifically derived trapezoidal  
shape and equipped with fly-points for use with the  
Fender RigSaferigging and flying hardware (except  
"c" versions), the speakers are designed for use as a  
single unit or as part of a larger loudspeaker array. The  
RigSafe system is compatible with both the JBL  
S.A.F.E.and the ATM Flywarecomponents.

Cast Frame Woofer  
B & C 1" (2.55cm) Exit Compression Driver  
Featuring a passive Linkwitz-Riley crossover, bi-amp  
capability, high power handling and variable horizontal  
coverage patterns, the 2912(c) /2915(c) is designed  
to form the basis of anything from a P.A. system for a  
band to a full-size concert sound tour system. After  
moisture sealing, the 2912 / 2915 cabinets are painted  
with an environmentally friendly tough black finish for  
long life and lasting looks. The 2912c / 2915c are  
covered in a rugged black carpet with the addition of  
metal corners and feet. These speakers are ideal for  
use as a two-way system or as the mid / high pack in  
a three-way set-up incorporating a 118s(c) or 215s(c)  
subwoofer loudspeaker system.  
Reinforced for Flying Applications  
(except "c" versions)  
CAUTION: Almost all speakers produce strong  
magnetic fields which may interfere with the  
normal operation of nearby electronic devices,  
including televisions and computer video  
monitors. To reduce or eliminate interference,  
increase the distance between this product and  
other nearby electronic devices.

When the switch on the back of the speaker is in the  
bi-amp mode, the internal crossover and high  
frequency attenuator are disabled. Thus, an external  
crossover must be used with the speaker and two  
channels of power amplification will be required: one  
for the low frequencies and another for the high  
frequencies. In bi-amp mode, the connections are as  
follows:

Two speakers in a "loose pack" array  
requiring maximum horizontal

If the speaker is part of a tightly packed array (see figure  
below), the coverage pattern should be modified to  
reduceoverlappingradiatingpatternsofmultipledrivers.

A second consideration is for feedback and bass  
performance. If the speaker is placed near a large, flat  
wall,thebassoutputwillbeincreasedbyapproximately  
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.  
HORN INSERTS  
To change the dispersion pattern from 90º to 60º, first  
removethegrillefromthespeaker. Usingasmallscrew  
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.  
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).

Installing the 2912(c) / 2915(c) horn insert  
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 Dispersionhorn 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.

Hours of testing and listening are used to determine  
the crossover point and filter slopes for each speaker.  
This information is then used to design the built-in  
passive crossover. For versatility and increased  
headroom, some users may wish to use an active  
electronic crossover / processor, such as the Fender  
PCN-2 or PCN-4, with the system. This electronic  
crossoverorprocessorwilltaketheplaceoftheinternal  
crossover of the speaker system. The "Normal / Bi-  
Amp" switch on the back of the cabinet must be set  
to the "Bi-Amp" position. A typical set-up of a bi-amp  
configuration is shown at right.

For those situations requiring a subwoofer, the 2912(c)  
/ 2915(c) can still be amplified if a three-way electronic  
crossover is used. An example of this configuration is  
shown on the next page.

It is strongly recommended that a fourth-order  
"Linkwitz-Riley" or a digital FIR fourth-order active  
crossover be used. The crossover frequency, for both  
the 2912(c) / 2915(c), should be set at approximately  
2000 Hz. Since the output sensitivity of the  
compression driver is higher than that of the woofer,  
the high frequency output of the system must be  
decreased at either the crossover (if such a control is  
provided) or at the power amplifier(s) that are used for  
the high frequencies.

WARNING: (2912 / 2915 only) The length of the useful life of these cabinets will depend in substantial part upon how they  
are treated in use. The user of this cabinet must periodically have this cabinet inspected to ensure that continued use has  
not weakened the cabinet's structure, including the various joints which are fastened with glue and/or screws. Because  
this cabinet is in some instances, suspended from heights in use and could cause serious injuries or fatalities if it falls, this  
determination is important and must be attended to by the user.  
For questions concerning flying your 2912 or 2915, please refer to the "Flying with Fender RigSafe" booklet (P/N 049646)
