Abstract

A loudspeaker system designed for ceiling installation. The system includes a woofer, a midrange speaker and a tweeter commonly supported on a rotatable support member which in turn is supported on and is rotatable with respect to an annular rim that is designed to be fixed about an opening in the ceiling. The woofer is aligned at one acute angle and the midrange speaker and tweeter at another acute angle to the annular rim. The mid range speaker and tweeter are partially segregated from the woofer by a baffle.

Claims (14)

1. A loudspeaker system comprising a woofer, a midrange speaker, and a tweeter, the midrange speaker and the tweeter being positioned in front of the woofer, the loudspeaker system comprising:

support means having a mounting member shaped to be received in an opening, wherein said mounting member is in a first plane;

means for mounting the woofer on the support means, wherein a center axis of the woofer on the support means is at a first acute angle to the first plane;

means for securing the midrange speaker and the tweeter in front of the woofer, a plane of the midrange speaker and the tweeter being at a second acute angle with the first plane; and

a midrange speaker and tweeter baffle positioned between the woofer, and the midrange speaker and tweeter, wherein the midrange speaker and tweeter baffle extends partially in front of the woofer.

2. The loudspeaker system of claim 1 , wherein the baffle directs tweeter and midrange speaker sounds angular to a primary direction of sound emanating from the woofer.

3. The loudspeaker system of claim 2 , wherein the baffle is a fructo conic baffle with one end secured to the face plane of the woofer.

4. The loudspeaker system of claim 3 , wherein the mounting member further comprises an annular member, and wherein the loudspeaker further comprises a grill cover extending across and secured to the annular member, the support means including a support housing the baffle.

5. The loudspeaker system of claim 3 , wherein the mounting member further comprises an annular member and wherein the loudspeaker system further comprises means for rotating the woofer, midrange speaker, and tweeter with respect to the mounting member.

6. A loudspeaker system comprising a woofer, a midrange speaker and a tweeter, where the midrange speaker and tweeter are positioned in front of the woofer, means supporting the woofer, speaker and tweeter for mounting within a structure having a surface with an opening therein with one side of the system essentially flush with the opening, means positioning the woofer within the structure with its axis at an acute angle to the surface, means positioning the speaker and tweeter intermediate the surface and the woofer with the axis of each of the speaker and tweeter at an acute angle to surface which angle is non-parallel to the angle of the woofer.

7. The loudspeaker system of claim 1 , having means for relative axial rotation of said support means and said woofer mounting means.

8. The loudspeaker system of claim 1 , wherein said woofer, midrange speaker, and tweeter are secured in fixed rotation to one another to said mounting means, and wherein the system further comprises means for rotating said support means and said means mounting said woofer relative to one another.

9. The loudspeaker of claim 1 , wherein said first acute angle and said second acute angle are not the same.

10. The loudspeaker system of claim 1 , wherein said second acute angle is larger than said first acute angle.
