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/amplifier package within a highly optimized enclosure to deliver an exceptional listening experience in your home theater or home audio system.

The subwoofer driver in your E-Sub subwoofer system is capable of outstanding linear excursion without distress or audible distortion. This purposeengineered driver enables your E-Sub to reproduce powerful low-frequency events with stunning impact and outstanding accuracy. The E-Sub drivers offer 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 amplifier. The E-Sub amplifiers 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.

The 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.

The 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 filtered output to the main speakers’ amplifier, while delivering a low-pass filtered signal to the internal subwoofer amplifier. 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. The 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! IT IS A VERY GOOD IDEA TO READ THE NEXT SECTION IMPORTANT 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. The physical dimensions of the room and its furnishings, materials, doors and windows play an important role in defining 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 softer, 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. These fundamental room resonances are called room “modes.”

The 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. The 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 find 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 floor, near the front left 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

The 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. These 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

Recommended Subwoofer Placement Options for 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

benefits can be substantial.

High-resolution measurements

and professional system calibration

are recommended for the best possible

results & system performance.

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).
