[. . . ] We recommend that you use a marked cable in order to conserve the polarity of the speakers (+/-). Cut the dry wall using the template supplied (fig. Be sure to check that this is perfectly vertical using a spirit level before you begin cutting. Check construction plans of your room to make sure that you are not drilling into a pipe, an electrical cable or any other specialised installations behind the wall. [. . . ] In order to obtain a realistic 3D soundstage, the placement of the speakers is decisive, even when confronted with a restrictive disposition of the listening room. For enhanced performances, the following elements should be noted. Central channel speakers should be placed close to the TVscreen to obtain a proper placement and a realistic reproduction of the dialog (fig. They could be placed below or above the TV-screen if your TV-unit permits. If a standart projection screen is used, the central channel speaker must be placed under the screen. If an acoustically transparent projection screen is used, the central channel speaker can be placed behind and at the bottom of the screen. Avoid placing the effect speakers too far from the listening area otherwise the sound perception will be altered. In order to obtain surround effects, with great sound density we advise you to place the speakers against the sidewalls on each side of the listening room (fig. You can use an in-ceilling surround speakers (fig. Tweeter adjustment To carry out adjustments, use the switch level located on the front baffle of the speaker as follows (fig. Precautions As the loudspeaker's covering materials are strong, scratch and stain-resistant, maintenance is easy and consists only in cleaning the covering with a dry cloth. If the enclosure is stained, we simply recommend the use of a damp cloth. Never use any solvents, detergents, alcohol or corrosive products, scrappers or scouring powder to clean the surface of the loudspeaker. Avoid placing the loudspeakers near a heat source. Running-in period The drivers used in the Custom line loudspeaker are complex mechanical devices and require a run-in period before they deliver their best performance. They must get adapted to the temperature and humidity conditions of their environment. This breaking-in period depends on the encountered conditions and can last several weeks. In order to shorten this period, we advise you to let your loudspeakers operate for about twenty hours at medium level, playing standard musical programmes, but with a large amount of bass.
