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 JLAudio
subwoofer driver and electronics/amplier 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 purposeengineered driver enables your E-Sub to reproduce powerful low-frequency
events with stunning impact and outstanding accuracy. e E-Sub drivers oer
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 amplier. e E-Sub ampliers 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 highpass ltered output to the main speakers’ amplier, while delivering a low-pass
ltered signal to the internal subwoofer amplier. 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.
IMPO RTANT
If you require assistance, we urge you to contact your authorized
JL Audio retailer for expert setup advice and service.
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.

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 dening 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 soer, 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.

Using Two E-Subs
When using two E-Subs, try
placement near the front corners of the
room, at diagonally-opposite corners
of the room, or at the center points of
opposing walls as shown at right.
Experimentation with
subwoofer and listener
placement is recommended to
achieve the best results – the
benets can be substantial.
High-resolution measurements
and professional system calibration
are recommended for the best possible
results & system performance.

Recommended Subwoofer Placement Options for Three E-Subs
Using Three or Four E-Subs
Research indicates that the
smoothest bass response for a large
listening area can be achieved using
four subwoofers, placing one at
the midpoint of each of the four
walls (although using two or three
subwoofers can be almost as good).
