Abstract
A composite speaker system for automotive vehicles in which a low-range speaker unit is mounted flush with a rear parcel shelf of the vehicle and a medium- and high-range speaker is mounted above the low-range speaker having an angular orientation which is adjustable in a vertical plane with respect to the center axis of the low-range speaker wherein the medium- and high-range speaker can be directed into the passenger compartment without reflection from the rear window. In one embodiment, the medium- and high-range speaker is rotatably mounted upon a grill frame which is detachably disposed upon and engaged with the open surface of the low-range speaker. In a second embodiment, first and second spacers extend from the center of the low-range speaker through the grill frame for the low-range speaker. In this case, the medium- and high-range speaker is tiltably mounted upon the upper end of the spacers. The medium- and high-range speaker may also be made horizontally rotatable.
