Your new JBL powered subwoofer incorporates a high-performance transducer and built-in amplifier that delivers the powerful, dynamic and accurate low-frequency performance that makes your film soundtracks and music come alive. And with adjustable crossover, phase controls and automatic turn on/off, it is also simple to connect and set up.
This quick-start guide contains all the information you need to set up, connect and adjust your new subwoofer. For more in-depth information, go to our web site: www.jbl.com.
Note: Type of power plug varies by regions.
The performance of a subwoofer is directly related to its placement in the listening room and its physical position relative to the other speakers in the system.
While it is true that in general our ears do not hear directional sounds at the low frequencies where subwoofers operate, when installing a subwoofer within the limited confines of a room, the reflections, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, the specific location of the subwoofer in the room does become important to the amount and quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will increase the amount of bass in the room; placing it in a corner (1) generally will maximize amount of bass in the room. However, corner placement can also increase the destructive effect of standing waves on bass performance. This effect can vary depending on the listening position – some listening positions may yield very good results while others may have far too much (or too little) bass at certain frequencies.
In many rooms, placing the subwoofer along the same plane as the left and right speakers (2) can produce the best integration between the sound of the subwoofer and that of the left and right speakers. In some rooms, the best performance could even result from placing the subwoofer behind the listening position (3).
We strongly recommend that you experiment with placement before choosing a final location for your subwoofer. One way you can determine the best location for the subwoofer is by temporarily placing it in the listening position and playing music with strong bass content. Move around to various locations in the room while the system is playing (putting your ears where the subwoofer would be placed), and listen until you find the location where the bass performance is best. Place the subwoofer in that location.
Please be sure to review the owner's manual for your receiver or processor for more information on speaker setup and configuration.

Set the subwoofer's Power Switch to the 'On' position. Now set the subwoofer's Power Mode to the 'Auto' position. The subwoofer will automatically turn itself on when it receives an audio signal, and it will go into Standby mode after it has received no audio signal for approximately 10 minutes. The subwoofer's LED will glow blue when the subwoofer is on and will glow red when the subwoofer is in Standby.
If you will not be using the subwoofer for an extended period – for instance, if you're going on vacation – set the Power Switch to the 'Off' position.
The Crossover control adjusts the subwoofer's built-in low-pass filter crossover between 50Hz and 150Hz. The higher you set the Crossover control, the higher in frequency the subwoofer will operate and the more its bass will 'overlap' that of the speakers. This adjustment helps achieve a smooth transition of bass frequencies between the subwoofer and the speakers for a variety of different rooms and subwoofer locations.
To set the Crossover control, listen for the smoothness of the bass. If the bass seems too strong at certain frequencies, try a lower Crossover control setting. If the bass seems too weak at certain frequencies, try a higher Crossover control setting.
Use the volume control to set the subwoofer's volume. Turn the knob clockwise to increase the subwoofer's volume; turn the knob counterclock-wise to decrease the volume. Once you have balanced the subwoofer's volume with that of the other speakers in your system, you shouldn't have to change the volume control setting.
Notes on Setting Subwoofer Volume:
The Phase switch determines whether the subwoofer driver's pistonlike action moves in and out in phase with the speakers. If the subwoofer were to play out of phase with the speakers, the sound waves from the speakers could partially cancel out the waves from the subwoofer, reducing bass performance and sonic impact. This phenomenon depends in part on the placement of all the speakers relative to each other and the listener(s) in the room.
Although in most cases you should leave the Phase switch in the 'Normal' position, there is no absolutely correct setting for the Phase switch. When the subwoofer is properly in phase with the speakers, the sound will be clearer and have maximum impact, and percussive sounds like drums, piano and plucked strings will sound more life-like. The best way to set the Phase switch is to listen to music that you know well and to set the switch in the position that gives drums and other percussive sounds maximum impact.
Four metal spikes are supplied for use when you place the subwoofer on a carpeted surface. Do not use these spikes when placing subwoofer on non-carpeted surfaces.
To insert the spikes:
Note: NEVER drag the subwoofer to move it. Always carefully lift the subwoofer and carry it to its new location.
