[. . . ] The grille logo on each speaker may be rotated depending on how the speaker is positioned. Gently pull the logo away from the grille slightly, rotate it to the desired position, and let go. When mounted vertically, the tweeter array may be positioned either up or down, depending on the height of the placement. If the speakers will be above ear level, the tweeter array should be positioned down, preferably no more than two feet above ear level. [. . . ] The enclosures are specially designed to angle the speakers toward the listener when mounted flush against the wall. When mounting the speakers outdoors, we recommend that you place them under an overhang, such as roof eaves, for added protection, and that you use two of the supplied special angle-mount screws per speaker, which angle the speakers downward at a greater-than-usual angle, facilitating water drainage. NOTE: When using the enclosed angle-mount screws, always use the top two screw locations appropriate for the specific mounting orientation of your LX300. Referring to the enclosed installation template, screw locations (1) and (2) are to be used when mounting the LX300 horizontally so that these locations are on top. To mount the loudspeakers vertically, use locations (2) and (4) or locations (1) and (3), depending on the mounting orientation. Do not mount the speaker upside down (with screw locations (3) and (4) on top) because it won't be able to lock onto the screw heads. Remember that the JBL logo on the tweeter/mid faceplate can be Roof eave Supplied Angle-Mount Screw (When using angle-mount screws, always utilize the top two screw holes on the LX300, depending on mounting orientation. ) Horizontal mounting: Use screwholes (1) and (2).
