ABSTRACT:
A flush-mount swivel tweeter system for vehicular audio utilizes a tweeter unit enclosed in hemispherical shell housing, which fits in a swivel manner into a mating cavity in a mounting bushing configured externally with a threaded sleeve having a thin peripheral decorative front flange. The resulting swivel tweeter assembly can be flush-mounted through a round opening provided in the host panel. The flange is secured against the panel by a large mounting nut threaded onto the mounting bushing from the rear. A circular aiming range is available by a combination of swivelling the tweeter unit off-axis and rotating the entire assembly in the panel opening. Once aimed, the swivel tweeter is clamped in place by a nut and washer at the rear, and the mounting bushing is secured in place by tightening the large mounting nut against the rear of the panel.
