Product Description  
The 12.1P is a self contained, powered 12" subwoofer providing over  
300 watts continuous output to the speaker. The 12.1P makes the  
addition of a subwoofer to a EVID system very easy and efficient. Since  
the unit is self-powered, the full range satellite speakers can be powered  
independently from the subwoofer and optimized for the installation.  
The 12.1P features a high performance, variable, 12-dB/octave  
crossover and a full range line level output along with a high pass line  
level output on the rear panel. The unit can be mounted in a variety of  
configurations with the bracket hardware supplied.  
Product Feature Identification  
The 12.1P subwoofer comes with a dual-mode mounting bracket that  
enables the unit to be easily mounted at either a wall/wall (corner) or on  
a wall/ceiling (midwall) junction. The included forged steel eyebolt  
provides the installer a solid attachment point for a safety line. When  
properly anchored and supported, the 12.1P subwoofer may also be  
safely installed protruding just 2 3/4" down through a standard sus-  
pended ceiling grid. See installation instructions.

Step-by-Step Installation & Wiring  
Step 1: Mount the Bracket  
The mounting bracket can be installed two ways (see Figures 5 and 6),  
allowing optimal configurations for installations. Leave 1.5" of space  
between the bracket and the ceiling when installing in a corner! Attach  
the bracket to the wall with suitable fasteners screwed into structural  
members in the wall. Remember: It is the installer’s responsibility to  
insure that the structure can safely support the load.

Step 2: Install the Safety Line  
Using accepted safe rigging practices, secure one end of a suitable  
safety line (use cable, not chain, which will rattle) to a strong, secure  
point above the speaker, a point that can withstand the shock of the  
falling speaker. This is especially important in public spaces constructed  
with light gauge steel studs. Do not attach the safety line to the bracket!  
The safety line should prevent the speaker from falling if the bracket  
tears loose from the wall. Secure the other end to the eyebolt that is fully  
threaded into the enclosure.

Step 3: Wire the Speaker  
A typical wiring configuration is shown in Figure 7. It is highly advisable  
to support the unit while these connections are being made. When  
mounting the speaker in a corner mount configuration, a right angle XLR  
connector such as Neutrik #NC3MRC or equiv. is required for the signal  
connections (see Figure 7). Connect the line level signal from the mixer,  
pre amplifier or other source into the line input connector. Plug in the  
power cord and connect the unit to a standard 120VAC power source.  
The proper crossover setting is  
determined by the satellite  
speakers used. The following  
are general guidelines:  
Satellite  
Speaker  
Crossover  
Setting  
3.2  
4.2  
6.2  
110 Hz  
95 Hz  
80 Hz  
Adjust the crossover according  
to the chart above. Set the  
appropriate sub level before  
making the final mounting to the  
bracket.  
Figure 7: Wiring Configuration  
Step 4: Mount the Speaker to the Bracket  
First remove the two Phillips-head screws on the rear of the enclosure.  
Use the supplied eyebolt to mount one mounting clip to the top of the  
speaker as shown in Figure 8. Check to make sure that the wiring  
connections to the amplifier and the satellite speakers are correct and  
secure.  
For corner mounting  
Attach the four rubber mounting feet to the front side edges, and secure  
the safety line to the eyebolt. Lift the enclosure up to the ceiling and  
center it back it into the corner until it touches the bracket rungs, then  
carefully lower it so the top clip hooks over the top rung of the bracket  
(1). Insert one of the 3/8-16-thread Phillips-head screws through the  
remaining clip and, with the clip pointing up, thread the screw finger-tight  
into the lower mtg. hole on the enclosure (2, 3). Level the clip and tighten  
securely with a #3 right-angle Phillips screwdriver. Even though the

enclosure hangs from the top clip, always install the lower one to secure  
against possible disengagement of the top clip. Straighten the EV® logo  
and press firmly at its center to seat it securely into its mounting hole.

Figure 9: Midwall Mounting  
For midwall mounting  
Attach the four rubber mounting feet inside the corners on the side of the  
enclosure that will be against the wall and attach the safety line to the  
eyebolt. Insert one of the 3/8-16-thread Phillips-head screws through the  
remaining clip and keep it within arm’s reach. Lift the enclosure up to the  
ceiling and bring its back into contact with the bracket rungs. Slide the  
enclosure sideways to engage the clip over one bracket rung (1) and,  
while holding it tight against both rungs, insert the 3/8-16-thread screw  
with its clip into the remaining mounting hole so the clip engages the  
remaining bracket rung (2, 3). Finger-tighten the screw and straighten  
the clip. The enclosure may now be released. It will slide down the rungs  
until the four rubber feet are snug against the wall. Using a #3 right-angle  
Phillips screwdriver, securely tighten the second Phillips-head screw.  
Gently rotate the EV® logo a quarter turn and press firmly at its center to  
seat it securely into its mounting hole. See Figure 9.

Mounting through a suspended ceiling grid  
On the rear of the enclosure install and tighten two 3/8-16-thread forged  
steel eyebolts (one is included) with a 3/8" flat washer under each. Cut  
two pieces of ordinary drop ceiling L angle (wall track) 23 3/4" long and  
screw them to the top and bottom of the enclosure with 3/4"-long sheet  
metal screws, as shown in Figure 10. Connect all of the wires and  
suspend the enclosure, face down, by the eyebolts in accordance with  
accepted safe rigging practice. Adjust the length of the rigging cables so  
the tips of the installed L angles just rest on the ceiling cross-tees. This  
stabilizes the enclosure from rocking. Trim the ceiling panel to fit the new  
opening(s) and drop into place. It is the installer’s responsibility to assure  
that the chosen rigging points are strong enough to support the load.  
Warning: Never try to install this speaker in a suspended  
ceiling without proper rigging support!

Examples  
The EVID™ Series is a product family with the flexibility to fit the  
requirements of many different applications. Listed below are some  
suggested combinations for systems using the 12.1P with EVID full  
range speakers:  
Rich, full-sounding low-level background music and paging in a  
quiet restaurant, office, or retail space: use two EVID™ 3.2’s or  
C4.2’s for each 12.1P installed.  
Moderate-level music and paging in a sports bar/restaurant or  
upbeat retail space: install two or four EVID™ 4.2’s or C8.2’s for  
each 12.1P used.  
Electro-Voice®

Higher-level foreground music in bass heavy applications such  
as dance floors, amusement arcades, or loud bars: use one pair  
of EVID™ 6.2’s for each 12.1P.  
For example, a large hotel might use eight 3.2’s and two 12.1P’s  
in the dining room, eight 4.2’s and two 12.1P’s in the lounge, four  
6.2’s with two 12.1P’s surrounding the dance floor, 6.2’s around  
the pool, 6.2’s or 4.2s with or without 12.1P’s in the lobby, and  
3.2’s in the corridors.  
Characteristics of All Subwoofers  
While subwoofers do radiate sound omni-directionally (in all directions)  
and the sound is generally non-localizable (one can’t hear exactly where  
it comes from), subwoofer sound level still drops off the farther one  
moves from the subwoofer. The highest output and best room loading  
are accomplished with the subwoofer mounted in a corner at a three-  
boundary junction (wall/wall/ceiling or wall/wall/floor, an arrangement  
also referred to as 1/8 space). Mounting at a two-boundary junction (wall/  
ceiling, or 1/4 space) produces three dB less output, and mounting in the  
middle of a room in the ceiling (1/2 space) reduces output still another  
three dB.  
Subwoofers produce large amounts of long wavelength low-frequency  
energy. Every object has its own resonant frequency, and long  
wavelengths tend to excite large objects (like walls, floors, doors and  
ceiling panels). Anything loose in or on a ceiling or wall will buzz or rattle  
as a subwoofer’s level is increased. Most of these can be isolated and  
fixed with small, strategically placed bits of foam tape. Others may  
require driving additional nails or screws and perhaps some caulking to  
dampen their sympathetic movement.

Appendix C: Painting Process  
Remove the four screws securing the front hatch and lift off the  
hatch panel. Carefully twist and lift off the EV® logo and set it  
aside.  
The foam grille blocks are held in place by sharp pins protruding  
through the baffle board. Note the relative position of the foam  
and carefully lift the blocks off the pins. Mask around and over  
the amplifier panel with tape and heavy paper and tape a piece  
of heavy paper over the woofer. It is not necessary to remove  
any components.  
Clean the cabinet, bracket and clips by rubbing with a lightly  
dampened cloth. Do not use abrasives such as sandpaper or  
steel wool. Never use gasoline, kerosene, acetone, MEK, paint  
thinner, harsh detergents, or other chemicals, as these agents  
may cause permanent damage to the enclosure.  
After cleaning, apply two or more two thin coats of either latex or  
oil-based paint. Spraying is recommended, but a brush and  
small roller work very well. It is not necessary to paint all the way  
up to the woofer. Only the visible surfaces need to be painted:  
the hatch front and side edges, the exposed enclosure surfaces  
down to the hatch gaskets and about halfway under where the  
foam blocks sit. Likewise, the rear sides of the bracket and clips  
need not be painted. The hatch screw heads may be painted, if  
desired.  
When the paint is thoroughly dry, carefully unmask everything.  
Replace the foam blocks, pressing them gently down onto the  
sharp pins. Replace the hatch cover and tighten the four screws.  
Locate the small center hole, properly orient the EV® logo, and  
press it firmly into place at its center to reseat it in the mounting  
hole.

Appendix D: Troubleshooting  
Guide  
Problem  
Possible Cause(s) Action  
1. No sound  
Amplifier  
Verify that that the line level signal cable’s  
XLR connector has been pushed all the way  
into the ‘Low Level In’ jack on the amplifier  
panel. Turn the ‘Power’ switch on and the  
volume up until you can hear sound emitting  
from the 12.1p subwoofer. If there is still no  
sound, the problem is with the line level  
signal.  
Line level signal  
Connect a known working powered test  
speaker to the line level signal from the  
mixer, pre amplifier or other source. If there  
is no sound, check that all of the electronics  
are on, the signal routing is correct, the  
source is active, the volume is on and so on.  
Fuse  
Carefully remove the fuse holder from the  
power cord input with the use of a flat head  
screwdriver. Inspect the fuse for any  
damage. Blown fuses will typically show a  
smoke-like blackening on the inside of the  
glass. If this is the problem, replace the fuse  
with a 4A/250V, 20mm x 5mm fuse.  
Only replace this fuse with the same type  
and rated fuse to reduce the risk of fire.  
2. Poor low-frequency Speakers wired  
response out-of-polarity  
When two speakers are connected out  
of polarity (out of phase), the low frequencies  
will cancel each other acoustically. Carefully  
observe the wire markings or tracers on your  
full-range speaker wires. Verify that their  
amplifier (+) terminal is connected to the red  
speaker terminals and their amplifier (-)  
terminal is connected to the black speaker  
terminals.  
3. Intermittent output Faulty  
Check the low-level signal cable/XLR  
connector to make sure that it has been  
pushed all the way into the ‘Low Level In’  
amplifier panel jack. If crackling persists,  
remove the signal cable from the amplifier  
and its low-level signal source and check for  
a faulty connection between the connector  
and the cable. Make sure that all of the  
terminals on cable connectors have been  
properly soldered.
