We sincerely thank you for your purchase and invite you to read this
manual thoroughly in order to achieve the highest level of performance with
your E-Sub subwoofer system. Enjoy.
PRODUCT OVERVIEW
JL Audio E-Sub subwoofers combine a state-of-the-art JLAudio
subwoofer driver and electronics/amplier package within a
highly optimized enclosure to deliver an exceptional listening
experience in your home theater or home audio system.
e subwoofer driver in your E-Sub subwoofer system is capable of
outstanding linear excursion without distress or audible distortion. is purpose-
engineered driver enables your E-Sub to reproduce powerful low-frequency
events with stunning impact and outstanding accuracy. e E-Sub drivers oer
peak-to-peak excursion capabilities well in excess of 2.5 inches (64 mm - e110),
and 3 inches (76 mm - e112) to comfortably handle the dynamics of the most
demanding program material.
To get the most from this long excursion driver platform, your E-Sub
incorporates a precisely engineered switching amplier. e E-Sub ampliers are
capable of unclipped output voltages equivalent to 1200 watts (e110), and 1500 watts
(e112) of RMS power when referenced to the nominal loudspeaker impedance,
allowing us to take full advantage of each driver’s full excursion envelope.
e beautiful cabinet enclosing the workings of your E-Sub is also the result
of careful engineering. To contain the pressures created by the E-Sub driver, we
utilize solid, CNC-cut, MDF material with extensive internal bracing features
and advanced assembly techniques.
e E-Subs also include an on-board 2-way active crossover, permitting
them to support a conventional 2-channel audio system by providing a high-
pass ltered output to the main speakers’ amplier, while delivering a low-pass
ltered signal to the internal subwoofer amplier. A polarity switch and phase
control are provided to aid in achieving an optimal acoustic transition between
the subwoofer(s) and main speakers. Inputs are via a pair of line level stereo RCA
inputs or via a removable plug for speaker level inputs.
As you can see from this brief introduction, there is a lot of technology in
this compact subwoofer. e contents of this manual will explain the features,
and guide you through the setup and tuning of your E-Sub to help achieve an
outstanding low-frequency listening experience.
If you require assistance, we urge you to contact your authorized
JL Audio retailer for expert setup advice and service.
IMPORTANT IMPORTANT! IT IS A VERY GOOD IDEA TO READ THE NEXT SECTION
BEFORE UNPACKING YOUR E-SUB. UNPACKING THE SUBWOOFER NEAR
ITS FINAL LOCATION IS RECOMMENDED.

| e110 & e112Page 6
PLACING YOUR E-SUB IN YOUR LISTENING ROOM:
Your listening room or theater is an integral part of your sound reproduction
system. e physical dimensions of the room and its furnishings, materials,
doors and windows play an important role in dening how your system sounds.
When you place a sound source in an enclosed rectangular space, “standing
waves” are created, resulting from the relationship between the sound’s
wavelength and your room’s dimensions. In other words, standing waves result
from sound energy that is trapped in the room as it bounces back and forth
between opposing walls. Standing waves in the room create acoustic peaks and
dips where the sound is either louder or soer, based solely on your physical
position in the room. Energy also “builds up” at the room’s boundaries, creating
exaggerated bass response at certain frequencies. ese fundamental room
resonances are called room “modes.”
e moral of this mode story is to try and avoid seating positions in standing
wave peak or dip regions. It is highly recommended that you place your listening
chairs in areas where modal peaks and dips are moderate and do not reinforce
one another. e two most obvious areas to avoid are those near the exact center
of the room and those close to any of the room’s walls.
Just as your listening seat can be in a peak or dip region, so can your
subwoofer. When placed in a room corner, a subwoofer maximally excites the
room’s mode structure, creating the strongest output with the fewest dips. When
the subwoofer is pulled away from a corner or wall, the room modes are excited
less, which can alter the sound at your listening seat.
Be sure to experiment with both your listening seat position and subwoofer
position to nd the best solution. Careful experimentation usually leads to a
superior sounding system. Use our setup suggestions (illustrated on the opposing
page and the following pages) to get you started.
We recommend that you begin by placing your E-Sub in the front of the
room, on the oor, near the front le or right speaker. Placing the E-Sub near
solid walls will reinforce bass response and pulling it away from solid walls will
decrease bass. Increasing the distance between the subwoofer and the walls may
help to smooth upper bass response in some rooms.
We recommend that you avoid placing the E-Sub near windows to prevent
rattling and sound transmission to the outside world.
If you are planning to install your E-Sub
inside a cabinet, please refer to the
guidelines on page 8.

SPECIAL CONSIDERATIONS FOR BUILT-IN INSTALLATIONS
e E-Sub can be integrated into custom cabinetry by following a few
simple guidelines.
1) Allow 4 inches (10 cm) of clear space behind the E-Sub’s amp panel for
adequate cooling and connector clearance.
2) On all other sides (except the bottom), allow at least 2 inches
(5 cm) clearance for adequate ventilation.
3) While the E-Sub generally runs only warm during spirited operation, we do
recommend that adequate heat vents are included in any custom cabinet which
encloses the E-Sub. A pair of 3 inch (7.5 cm) diameter vents near the bottom of
the cabinet and near the top of the cabinet, will allow cool air to circulate over the
amp panel of your E-Sub subwoofer system keeping it cool and happy.
4) Your E-Sub subwoofer is capable of moving substantial quantities of
air. If the front of the E-Sub is covered by a custom grille, the grille
must have AT LEAST 85 square inches (548 sq.cm.) of vent area for
the e112, and AT LEAST 60 square inches (386 sq.cm.) for the e110.
ese areas are equal to the woofer cone area for each model and will
ensure that the E-Sub’s output is not choked by the custom cabinet.

TOP-MOUNTED CONTROLS IN DETAIL
Top-Panel Power Switch and Indicator LED
e “Power” switch on the top panel determines the operational readiness of the
E-Sub subwoofer and should be the only switch used to turn the E-Sub on and o
during typical use.
e top-panel “Power” switch has three positions:
“O ”: e E-Sub’s internal power amplier is powered down.
Indicator LED: red
In this stand-by state, a tiny amount of power is consumed (< 0.5 watt) to
energize the E-Sub’s so turn-on circuitry.
“On”: e E-Sub is fully operational.
Indicator LED: green
Power consumption will vary, depending on program material and level
“Auto”: e E-Sub will power up its internal amplier when it detects an audio
signal at any of its inputs, and will power down the internal amplier if no
signal has been detected at its inputs for approximately thirty (30) minutes.
While dormant, the E-Sub consumes a tiny amount of power (< 0.5 watt).
Indicator LED: amber (dormant) / green (operational)
In the unlikely event that the Auto Turn-On feature is not sensitive
enough for a particular system, use a Y-cable adaptor (one female to
two male RCA type connectors) to split the incoming signal into both
RCA inputs on the E-Sub. is will increase the input sensitivity by
6 dB. Please be aware that if there is signicant noise entering the
E-Sub’s input, the E-Sub may not turn o as desired. If this happens,
remove the Y-cable adaptor and/or look for the noise source in the
upstream components.
e only way to completely power down an E-Sub is to unplug its AC Power
Cord. Before disconnecting the power cord, always place the top-panel “Power” switch
in the “o” position (to prevent damaging pops and transient noises).
Do not use a power strip switch, switched outlet or any other external switch to
interrupt or engage power to an E-Sub in “auto” or “on” positions, as this will also result
in undesirable and potentially damaging transient pops.
Master Level Knob
e “Master Level” Knob is used to set the output level of the E-Sub, relative
to the rest of the audio system.
When rotated fully counter clockwise, the E-Sub’s output will be fully muted.
When at the “0” or straight up position, the level is at reference gain. When
turned fully clockwise, the E-Sub’s level is at its maximum sensitivity (loudest).
IMPORTANT

Page 15| e110 & e112
Crossover Switch
e “crossover” selector switch determines the operating mode of the E-Sub’s
built-in active crossover.
“O” defeats the crossover lter, completely removing this circuit from the
signal path and is most useful when using a receiver or preamp/processor’s lters
and bass-management features.
“On” activates the on-board active crossover. is crossover consists of a 24
dB/octave low-pass lter for signals feeding the E-Sub’s internal amplier, plus
a 24 dB/octave high-pass lter feeding the “Line-Outputs” on the E-Sub’s rear
connection panel. is is most useful when integrating the E-Sub into a two-
channel audio system.
Crossover Frequency Knob
e “crossover freq. (Hz)” selector knob allows the user to choose the
crossover frequency of the E-Sub’s built-in, active crossover. It has no eect when
the “crossover” switch is in the “o” position. e frequency is variable from 25
Hz (full counter-clockwise) to 130 Hz (full clockwise). 80 Hz is a commonly used
lter frequency and usually serves as a good starting point for adjustments.
Polarity Switch
e “Polarity” switch allows the user to select between normal (0 deg) and
reversed (180 deg) signal polarity. e “Polarity” switch will primarily aect the
small frequency range around the crossover point between your subwoofer and
satellite speakers.
Unlike the “phase (deg.)” control, which eectively adds time delay, the
“Polarity” switch produces an instantaneous reversal of the signal’s amplitude
peaks. For example, if at a given reference point a sine wave has an amplitude
peak, by ipping the “phase (deg.)” switch you instantly convert that peak
into a trough or amplitude dip. Because the eect of the “Polarity” switch
is immediate, it compliments the operation of the “phase (deg.)” control and
cannot be replaced by it.
When placing your E-Sub in the room, experiment with the “Polarity “switch
before adjusting the “phase (deg.)” control. Either position of the “Polarity” switch
may provide a smoother transition between your E-Sub and the satellite speakers.
Use source material with good mid and upper bass content for evaluation.

| e110 & e112Page 16
Phase Knob
e “phase (deg.)” control knob allows the user to adjust the timing of the
subwoofer output relative to the main speakers. e “phase (deg.)” control will
primarily aect the small frequency range around the crossover point between
your subwoofer and satellite speakers. e “phase (deg.)” control’s degree labeling
is referenced to 80 Hz, since this is the most common crossover point between
satellite speakers and a subwoofer. Phase settings between 0 degrees (full counter-
clockwise rotation) and 280 degrees (full clockwise rotation) are possible.
Speaker, subwoofer, and listening seat positions vary greatly in home theater
installations. Since physical positioning of speakers relative to the room
boundaries and each other greatly aects the perceived quality of sound output,
sometimes it is helpful to delay the subwoofer output. is is exactly what occurs
when you turn the “phase (deg.)” control beyond 0 degrees.
Once your E-Sub has been placed in your listening room to give you the
smoothest overall sound, and aer you have determined the optimum “Polarity”
switch position (see preceding section), experiment with the position of the
“phase (deg.)” control. Using familiar source material with good mid and upper
bass content, adjust the “phase (deg.)” control and listen for better dened mid-
bass and a smoother transition between the subwoofer and satellite speaker
systems. If no single setting sounds better than another, leave the “phase (deg.)”
control at 0 degrees.

CONNECTING YOUR E-SUB(S)
Line Inputs
e E-Sub features individual, le and right, unbalanced RCA-type
input connectors. ese are the most commonly used connectors for home
audio applications.
For systems with a mono subwoofer or “LFE” channel connection, only one
RCA-type jack will be used (Le or Right). is method applies to most modern
multi-channel receivers and preamplier / processors.
Separate le and right RCA-type input jacks are provided for systems without
a dedicated mono subwoofer connection. is typically applies to two-channel
audio equipment. In a two-channel application, you must supply separate le and
right inputs to a single E-Sub in order to have high-pass ltered, stereo outputs
from its Line Outputs. e E-Sub will automatically sum the le and right inputs
to feed its internal subwoofer amplier.
RCA-type connectors (one for each channel):
Tip: Positive
Sleeve: Negative
Input Impedance: 10 kΩ
“Grounded / Isolated” Switch
is feature is included to deal with the signal grounding issues oen
encountered in home theater systems when several components from dierent
manufacturers are interconnected. e “Grounded / Isolated” Input Mode switch
on the rear connection panel alters only the “Line Inputs” and is designed to
facilitate a quiet, hum-free connection to your audio or home theater system. is
switch has no eect on signals connected to the “High-Level Inputs”.
e E-Sub ships with this switch in the “Isolated” position. If, with all system
components connected and turned on (but no source material playing), you
hear a continuous low-frequency hum through your E-Sub, ip this switch to the
“Grounded” position and evaluate the dierence in the noise level. Use whichever
switch position provides the least hum or noise.
High Level Inputs
is feature is included for convenience when needing to connect the E-Sub
to a receiver or integrated amplier that only oers speaker level outputs. It is not
the preferred method when a line-level signal is available.
To use the “High Level Inputs” feature, simply connect the speaker outputs of
the receiver or integrated amplier to the “High Level Input” plug of the E-Sub, in
parallel with the main speakers. e main speakers will remain full-range in this
application and their sound will not be aected by the connection to the E-Sub.
e “High Level Input” consists of an input connector and removable plug
with captured-wire receptacles. Standard speaker cable, up to 12 AWG (3 mm2),
can be used and connected to the removable plug by backing out each set screw,
inserting the bared end of each speaker wire, taking care not to short any wire to
another, and tightening the set screw. Connections are as follows:
“High Level Input” Connector (from le to right):
1: Right Channel Negative
2: Right Channel Positive
3: Le Channel Negative
4: Le Channel Positive
Input Impedance: 4.3 kΩ
e Le and Right inputs on the E-Sub are
internally summed to a single mono channel.

Line Outputs
e E-Sub features individual, le and right, unbalanced RCA-type output
connectors to feed a second subwoofer or an amplier powering main stereo
speakers. e “Line Outputs” can be used in two distinct ways, depending on
your system’s conguration.
Crossover On: High-Pass Filtered Outputs
When the E-Sub’s on-board crossover is engaged (“Crossover” switch in
the “on” position - page 15), the “Line Outputs” will deliver a high-pass ltered
signal according to the frequency selected by the “crossover freq. (Hz)” knob.
is creates a true, two-way, 24 dB/octave, Linkwitz-Riley crossover between the
E-Sub and the main stereo speakers.
Please note that you must supply separate le and right channel stereo inputs
to the E-Sub in order to have high-pass ltered, stereo outputs from its “Line
Outputs”. If you supply only one channel of input to the E-Sub, only the line
output corresponding to the input with signal will deliver a high-pass ltered
signal (the other line output will have no signal). If you are using two E-Subs in
a two-channel system, you can assign one E-Sub to the le stereo channel and
the other E-Sub to the right stereo channel, using only one “Line Input” and one
“Line Output” per E-sub.
Crossover O: Pass-rough Subwoofer Output
When the E-Sub’s on-board crossover is defeated (“Crossover” switch in the
“o” position - page 15), the “Line Outputs” will deliver a pass-through, buered
signal that is identical to the signal feeding the E-Sub’s “Line Inputs”. is is very
useful for passing a subwoofer signal from one E-Sub to another E-Sub in a multi-
subwoofer installation.
AC Power Connector
e IEC-style AC cord receptacle receives the heavy-gauge, 6 . (1.8 m) long,
power cord included with your E-Sub subwoofer. E-Subs sold in dierent parts
of the world are congured for each market’s electrical system and include
approprate plugs on their power cords. Please note the voltage markings next
to the AC Connector and make sure you are only powering the E-Sub from a
receptacle that matches these markings. Do not use any AC power cord other
than the one supplied with the E-Sub.
e E-Sub subwoofer is a very powerful device and can draw a lot of current.
If too many components are connected with an E-Sub subwoofer to one electrical
outlet, you risk tripping a household circuit breaker during very demanding
program material. If this happens, split the E-Sub and other components between
two AC electrical circuits.

SYSTEM CONNECTION DIAGRAM 1:
One E-Sub to Home Theater Receiver
or Home Theater Preamp/Processor
Most home theater receivers and
preamp/processors provide a single
(mono) subwoofer line-level output.
When connecting a mono
subwoofer output to your E-Sub, you
only need to connect to one of the
E-Sub’s “Line Inputs” (Le or Right). Use
a good-quality audio interconnect cable
with RCA-type connectors.
In most cases, you will use the bass
management/crossover features of the
receiver or preamp/processor. is
requires that the E-Sub’s “Crossover”
switch is placed in the “O” position.

WARNING! TURN OFF THE E-SUB(S) AND ALL OTHER EQUIPMENT IN THE

SYSTEM CONNECTION DIAGRAM 2:
Multiple E-Subs to Home Theater
Receiver or Home Theater Preamp/
Processor
Most home theater receivers and
preamp/processors provide a single
(mono) subwoofer line-level output.
To greatly simplify the connection
of multiple subwoofers in a single home
theater system, E-Subs include a pass-
through line output feature. is allows
an input signal connected to one E-Sub to
be passed from that E-Sub to a second one,
and from the second E-Sub to a third, etc.
When connecting a mono subwoofer
output to multiple E-Subs, you only need
to connect to one of each E-Sub’s “Line
Inputs” (Le or Right). Run an audio
interconnect cable from the receiver/pre-
pro’s subwoofer output to one “Line Input”
of the rst E-Sub in the system. en run
a second audio cable from that E-Sub’s
corresponding “Line Output” to one “Line
Input” of the next E-Sub in the system, as
shown in the diagram. Additional E-Subs
can be added using the same method.
You must turn the E-Sub’s “Crossover”
o to use the pass-through signal feature,
allowing the receiver/pre-pro to perform
crossover/bass-management functions.
Make sure the “Crossover” switch on the
top control panel of the E-Sub is in the “o”
position to use this connection method.
Alternative Method:
If running cables from one E-Sub
to the next is not practical due to the
physical layout of the E-Subs relative
to the receiver/pre-pro, you can use a
Y-Adaptor cable (splitter) to split the
receiver/pre-pro output signal to multiple
audio interconnect cables, each feeding a
separate E-Sub.
Some receivers and preamp/processors
oer multiple subwoofer outputs, which
can also be used to connect multiple
E-Subs. Refer to the manual of your
receiver/pre-pro for details.
