S4S OM 10/18/05 12:02 PM Page 3 ® THANK YOU FOR CHOOSING JBL For more than 60 years, JBL has been involved in every aspect of music and film recording and reproduction, from live performances to monitoring the recordings you play in your home, car or office.
S4S OM 10/18/05 12:02 PM Page 4 SPEAKER PLACEMENT Low-frequency sounds are normally omnidirectional, meaning the listener can’t tell where they are generated from. However, frequencies between 75Hz and 150Hz can be localized, especially at higher volume levels. Positioning your subwoofer as recommended will provide the most natural soundstage and imaging from your loudspeaker system. It is generally recommended that you install your S4S in-wall subwoofer along the same wall as the front loudspeakers.
S4S OM 10/18/05 12:02 PM Page 5 SPEAKER CONNECTIONS Connection Tips Speakers and electronics have corresponding (+) and (–) terminals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (–) terminal. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier, and (–) on the speaker to (–) on the amplifier. Wiring “out of phase” results in thin sound, weak bass and a poor stereo image.

S4S OM 10/18/05 12:02 PM Page 7 INSTALLATION A complete S4S loudspeaker system includes the S4S in-wall subwoofer and the S4SBB back box. These components are packaged separately. NOTE: The THX Ultra2 standard requires that the S4S baffle be mounted vertically. Installation requires access to the space between the wall studs. Therefore, in new-construction applications, the S4SBB back box is installed before the wallboard.
S4S OM 10/18/05 12:02 PM Page 8 INSTALLATION Installation: 1. Place the Styrofoam™ blocks on the bottom plate of the stud bay. The S4SBB back box will rest on top of the blocks. 2. Install the two centering bars as shown in Detail A on page 6. The centering bars are for setting the depth of the enclosure. They also help locate the horizontal position of the enclosure as they are mounted into the studs at the left and right to hold the enclosure in the correct location. 3.

S4S OM 10/18/05 12:02 PM Page 10 PAINTING THE SPEAKER FRAME AND GRILLE The S4S loudspeaker can be painted to match any décor. If you wish to change the color, the satin finish on the grille and frame will function as a primer coat. Before painting, install the plastic paint shield securely into the baffle. This will protect the speaker components and baffle from paint residue. Use a high-quality spray paint, and apply a thin coat of color.
S4S OM 10/18/05 12:02 PM Page 11 TROUBLESHOOTING SYMPTOM SOLUTION If there is no sound from any of the speakers: • Check that the receiver/amplifier is on and that a source is playing. • Check all wires and connections between the receiver/amplifier and the speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each other. • Review proper operation of your receiver/amplifier.
