Spend some time considering speaker placement prior to installing the 6 2 Ci Once the speakers are installed they are permanent so their location should be selected carefully Mount the speakers in a 1 5xD location where they face the listening area without obstruction from furniture and are preferably at least three feet from side walls The speakers should be mounted on a flat surface to ensure a good seal between the bezel and the mounting surface For optimal imaging position the speakers so that the distance between the listening position and the wall is 1 5 times the distance between the two speakers fig 1 If possible position the speakers so that the aver age ear height of the listeners in the room falls between the center of the tweeter and the center of the bottom most woofer To get an idea how the speakers will look in the room try taping the supplied cutout templates to the wall Keep in mind that room furnishings play an important role in absorbing and reflecting sound waves Midrange and high frequencies in particular will be absorbed by soft furnishings such as sofas carpets and curtains A large number of these soft furnishings will dull the sound while a live room with few furnishings will brighten the sound You can adjust the sound of the speakers in your room by adding or removing soft wall hangings curtains and furniture to achieve the sound that you desire Mounting Mounting Bezel Baffle with As the 6
