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.
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.

SPECIAL CONSIDERATIONS FOR BUILT-IN INSTALLATIONS The E-Sub can be integrated into custom cabinetry by following a few simple guidelines. 1) A llow 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.
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 benefits 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). Experimentation with subwoofer and listener placement is recommended to achieve the best results – the benefits can be substantial.
UNPACKING YOUR E-SUB Now that you have determined your E-Sub’s position on the floor of your room, you can proceed with unpacking it near its intended location. D Unpack this box close to where the subwoofer will be placed. The subwoofer is PACKED upside down. This box must be flipped over CAREFULLY to remove the subwoofer and minimize effort. IMPORTANT A B C IMPORTANT: DUE TO THE WEIGHT OF THE E-Sub SUBWOOFER, PLEASE EXERCISE CAUTION WHILE UNPACKING AND POSITIONING IT TO PREVENT INJURY.

TOP-MOUNTED CONTROLS IN DETAIL Top-Panel Power Switch and Indicator LED The “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 off during typical use. IMPORTANT The top-panel “Power” switch has three positions: “Off ”: The E-Sub’s internal power amplifier is powered down. Indicator LED: red In this stand-by state, a tiny amount of power is consumed (< 0.
Crossover Switch The “crossover” selector switch determines the operating mode of the E-Sub’s built-in active crossover. “Off” defeats the crossover filter, completely removing this circuit from the signal path and is most useful when using a receiver or preamp/processor’s filters and bass-management features. “On” activates the on-board active crossover.
Phase Knob The “phase (deg.)” control knob allows the user to adjust the timing of the subwoofer output relative to the main speakers. The “phase (deg.)” control will primarily affect the small frequency range around the crossover point between your subwoofer and satellite speakers. The “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.
CONNECTING YOUR E-SUB(S) Line Inputs The E-Sub features individual, left and right, unbalanced RCA-type input connectors. These are the most commonly used connectors for home Warranty void if serial number is audio applications. removed, altered or defaced. L L For CH. 2 CH. 1 systems with a mono subwoofer or “LFE” channel connection, only one SERIAL NUMBER: (R) (L) RCA-type jack will be used (Left or Right). This method applies to most modern Grounded multi-channel receivers and preamplifier / processors.
Line Outputs The E-Sub features individual, left and right, unbalanced RCA-type output connectors to feed a second subwoofer or an amplifier powering main stereo speakers. The “Line Outputs” can be used in two distinct ways, depending on your system’s configuration.
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” (Left 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.

SYSTEM CONNECTION DIAGRAM 3: One E-Sub in Mono to Two-Channel Audio System When connecting a single E-Sub in mono to a two-channel audio system you will use both the “Left” and the “Right” “Line Inputs” of the E-Sub and you will engage the E-Sub’s active crossover by selecting the “on” position on the “Crossover” switch located on the top control panel. The internal active crossover will apply low-pass filtering to feed the subwoofer’s internal amplifier with a summed L+R signal.

SYSTEM CONNECTION DIAGRAM 5: Connecting one E-Sub to a Receiver via the High-Level Inputs The E-Sub features high-level inputs designed to accept the output of an amplified source, such as a stereo receiver’s speaker outputs. The use of this feature is only recommended when no suitable linelevel signal is available. When connecting a single E-Sub in mono to a two-channel receiver’s speaker outputs, you will use both the Left and Right connections on the “High-Level Inputs” plug of the E-Sub.

RECOMMENDED SETUP PROCEDURES (continued) Subwoofer System Setup: Once you have set the controls on your home theater receiver or preamp/ processor and on your E-Sub(s) to the settings recommended on pages 24 and 25, you are ready to begin setting up your E-Sub for optimum performance. 1) Level Setting Using familiar music or movie material with deep bass content, adjust the subwoofer level to blend with the other speakers using your receiver or preamp / processor’s subwoofer level control.
FREQUENTLY ASKED QUESTIONS Can I place objects on my subwoofer? We do not recommend placing any items on the subwoofer cabinet as they may vibrate, causing undesirable noise and possible damage to the finish. Under no circumstances should any object containing liquid be placed on the E-Sub cabinet. Is the E-Sub magnetically shielded? NO. To avoid magnetic distortion with certain television types, place the E-Sub at least 3-4 feet (1 - 1.5m) from your screen.
CLEANING YOUR E-SUB Dust your E-Sub subwoofer’s cabinet using a clean, soft microfiber cloth or feather duster. Microfiber cloths are commonly available where automotive detailing supplies are sold. Gloss-black models: Light smudges can generally be wiped off with a clean microfiber cloth. For more stubborn smudges, polish and protect the finish using a high-quality automotive wax and a microfiber cloth, both available wherever automotive detailing supplies are sold.
TROUBLESHOOTING No sound from subwoofer. 1. Verify that E-Sub is plugged in, turned “ON” & that the top-panel LED is green. If the E-Sub will not power up, check the circuit breaker that feeds its outlet, or the AC power cord. 2. Verify that your receiver’s subwoofer settings have not changed. 3. If your other speakers play, but the E-Sub does not, try changing the cable that connects the E-Sub to the system. 4.
