[. . . ] Aim the tweeters away from each other, toward the front and rear of the room. The IS6DT has the capability of playing two channels through one speaker, thanks to its dualtweeter/dual-voice-coil construction. Since the tweeters are close together, in general they should be aimed away from each other for best coverage. For two-channel (stereo) applications, e. g. , as a single speaker in a remote room of a distributed audio system, install the 3 SPEAKER CONNECTIONS CONNECTION TIPS The wires for both speakers should be the same length. If one speaker is placed closer to the amplifier than the other, hide the excess wire behind the wall. Speakers and electronics terminals 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. With the advent of multichannel surround sound For model IS6DT, the terminals for both the left and right channels will systems, connecting all of the be on the same loudspeaker. speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material.

PAINTING THE SPEAKER FRAME AND GRILLE Performance Integrator loudspeakers can be painted to match any décor. If you wish to change their color, the satin finish on the grille and frame will function as a primer coat. Before painting, install the paint shield (inner section of template in the assembly kit) securely into the recess in 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. Be certain the grille perforations remain free of paint. Filling them with paint will diminish the sound quality. Note: Gently remove the acoustical foam blanket from the grille before painting. Reattach the blanket after the paint has dried. TROUBLESHOOTING IF THERE IS NO SOUND FROM ANY OF THE SPEAKERS: sure none of the speaker wires are frayed, cut, punctured or touching each other. IF THERE IS LOW (OR NO) BASS OUTPUT: · Check that receiver/amplifier is on and a source is playing. · Check all wires and connections between receiver/amplifier and speakers. Make sure none of the speaker wires are frayed, cut, punctured or touching each other. [. . . ] · Consider adding a powered subwoofer to your system. · In Dolby Digital or DTS modes, make sure your receiver/ processor is correctly configured. When using a subwoofer, make sure the subwoofer output of the receiver/ processor has been enabled. If no subwoofer is being used, make sure the left and right front and rear speakers have been configured as "LARGE.
