[. . . ] Remove the grille from its box and install it. Notice that the grille has 6 protruding studs. These studs mate with the plastic sockets in the cabinet. To install the grille, make sure the Altec Lansing logo is oriented at top, gently press the two top studs into the top part of the cabinet and then press the two in the bottom, the middle ones will just fall in place. [. . . ] When estimating the length of wire required for each speaker, allow a few extra feet. This is necessary because you may have to experiment to find the best location for maximum speaker performance, then cut the wires to exact size. Prepare the wires by stripping half of the insulation from the ends of the wire. Once the insulation is removed, twist the copper wire so that it will go into the speaker terminals more easily. If the speaker must be repeatedly moved, connecting the speaker wires to banana plugs may be desirable. These plugs are available at all audio outlets. Notice that most wires have some kind of marking (either a color strip or ridges) that allow you to differentiate one conductor from other. These markings are important for phasing of the speakers. To obtain maximum bass response it is important that all speakers operate in union (speakers are phased). Locating the Speaker for Best Performance The location of the speakers in a room is usually dictated by space that is available and room décor. In most instances, a few changes to the room will help achieve the best sound performance. Certain basic considerations can be accommodated to achieve good results. Now it's time to consider how to maximize the fun and excitement your equipment offers. This manufacturer and the Electronic Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets sound come through loud and clear without annoying blaring or distortion ­ and, most importantly without affecting your sensitive hearing. Over time your hearing "comfort level" adapts to higher volumes of sound. So what sounds "normal" can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. To Establish a Safe Level · Start your volume control at a low setting. · Slowly increase the sound until you can hear it comfortably and clearly and without distortion. · Once You Have Established a Comfortable Sound Level, set the dial and leave it there. Taking a minute to do this now will help prevent hearing damage or loss in the future. After all, we want you listening for a lifetime. [. . . ] This is achieved by special high temperature wire, adhesive and coil forms. However, damage may occur to the midrange and tweeter when these speakers are operated from amplifiers that are highly distorted. Usually some lower power handling amplifiers are easily driven into "clipping" levels. Even though the amplifiers are low power, the distorted wave forms can cause damage more so than the high power clean amplifiers. [. . . ]
