[. . . ] (20-30 cm or 8-12 in) will change the perceived tonal balance. When a satisfying balance is found, a proper sound stage and stereo localization is developed by smaller movements of the loudspeakers in combination with angling towards the listening position. we strongly recommend experimentation in order to find the most satisfying overall sound. Attention to every detail of the setup will be beneficial in terms of improved sound quality. [. . . ] 75-10 m (30-40 in) distance to the side walls. A good guideline to proper setup is to start by concentrating on the tonal balance of the sound, aiming for the most neutral reproduction. Is the bass too strong or too weak compared to the midrange and treble?Moving the speakers around in relatively large steps, Connections to the loudspeaker system are made at the terminals located on the back of the enclosure. these terminals permit a variety of connection methods. The most straightforward connection is made by directly connecting clean bare wire. This connection is made by stripping 8-10 mm of insulation off the loudspeaker wire and passing the bare wire through the hole in the binding post. If the wire is too thick to pass through the hole in the terminal in one single bundle, separate the copper wire into three equal bundles, then pass the center bundle through the hole in the terminal. Wrap the remaining bundles around the binding post and twist the center stands. The knob can now be tightened securely, and any excess wire that is not in contact with the binding post surfaces should be trimmed to avoid short circuits. A very convenient way of connection is the use of 4 mm banana connectors, which are then, in turn, connected to the binding posts. The system's internal dividing networks are electrically separated at the low frequency to midrange/tweeter transition. External strapping bars connect the two parts of the network when a single wire connection is used. The system is shipped from the factory with the strapping bars in place. By removing the bars, connections may be made to the individual network sections using two wires (four conductors) as shown in Figure 1. The wires used may be of the same type for both low frequency and high frequency sections. Four identical amplifiers (or two dual channel units) may be used, although specialized low and high frequency amplifiers can offer clear advantages. Your JBL Ti-Series dealer can recommend amplifiers that best suit your needs. In all cases, the left and right amplifiers for each section must be identical. Ensure that the input sensitivity of the two amplifiers is equal or that input level controls are provided to maintain proper low to mid/high balance. If two identical stereo amplifiers are chosen, each amplifier may be located near a loudspeaker and drive low frequency and high frequency sections through short wire runs. beware that some amplifiers invert the polarity of the signal. [. . . ] Never use any abrasive cleaners or strong chemical to clean the enclosure. To remove the grille, grasp two corners and gently pull the grille away from the enclosure. Any dust on the grille should be removed using a cleaning brush or a vacuum cleaner. The JBL Ti-Series speakers are capable of handling peak power far exceeding the continuous rating specified for the individual speakers. [. . . ]
