[. . . ] So don't hesitate to experiment on your own. 40 100 200 300 400 500 40°-60° Fig. 1 Thanks to their high efficiency, JBL loudspeakers will produce reasonable volume levels in a room of moderate size with very little amplifier power. [. . . ] We recommend #16 AWG wire as a minimum size. If your speakers are more than 30 feet (10 m) from your receiver or amplifier, use larger diameter wire. Connections are made at the terminals located on the back of the loudspeaker system. The terminals accept bare wire or dual banana plugs, either of which will provide easy, secure connections. Amplifier/ Receiver +L+R Fig. First determine the distance between the most distant speaker. Now make the hookup wires for both speakers this length, even if one loudspeaker is much closer to your amplifier than the other. This will help maintain proper signal balance. 2 For each channel, the red terminal on the loudspeaker should be connected to the red or (+) loudspeaker connection terminal on the receiver or amplifier, and the black to the black or (­). Connecting the loudspeakers in this manner ensures that they will be in phase; that is, work together rather than in opposition. Connecting the loudspeakers out of phase will not damage them, but will result in less bass and poor imaging.
