Abstract
Abstract A speaker system employs a baffle board in the front part of the cabinet with a woofer mounted on said baffle board. A selfcontained auxiliary speaker device covering middle and high-pitch tone ranges is further mounted on the baffle board in such a manner that the angle between the auxiliary speaker device and the baffle board can be varied as desired.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
In a speaker system comprising two laterally spaced speaker assemblies, each speaker assembly being in the form of a cabinet having a baffle board on the front of said cabinet with said laterally spaced speaker assemblies generally facing an auditor at right angles to a plane defined by the baffle boards of respective cabinets with the auditor being spaced some distance therefrom, the improvement comprising; a woofer mounted on the baffle board of each cabinet with the sound emanating therefrom generally at right angles to the baffle board, an auxiliary speaker device in the form of a self-contained speaker for at least the high-pitch tone range, and means for mouNting said device on each baffle board such that the angle of directivity between the auxiliary speaker device and the plane of the baffle board may be varied universally to permit each auxiliary speaker to have its sound directed specifically towards said auditor.
Claim 2
Dependent Claim
152 words
In a speaker system comprising two laterally spaced speaker assemblies, each speaker assembly being in the form of a cabinet having a baffle board on the front of said cabinet with said laterally spaced speaker assemblies generally facing an auditor at right angles to a plane defined by the baffle boards of respective cabinets with the auditor being spaced some distance therefrom, the improvement comprising; a woofer mounted on the baffle board of each cabinet with the sound emanating therefrom generally at right angles to the baffle board, an auxiliary speaker device in the form of a self-contained speaker for at least the high-pitch tone range, and means for mouNting said device on each baffle board such that the angle of directivity between the auxiliary speaker device and the plane of the baffle board may be varied universally to permit each auxiliary speaker to have its sound directed specifically towards said auditor.
Claim 3
Dependent Claim
13 words
The system of claim 1 wherein said mounting means comprises a universal mounting.
Claim 4
Dependent Claim
41 words
A speaker system as defined in claim 1 wherein said auxiliary speaker device mounted on the baffle board is supported thereon through vertical shafts and horizontal shafts so that the auxiliary speaker device can be rotated about vertical and horizontal axes.
Claim 5
Dependent Claim
41 words
A speaker system as defined in claim 1 wherein said auxiliary speaker device mounted on the baffle board is supported thereon through slidably contacting spherical surfaces so that the auxiliary speaker device can be rotated in mutually distinct right angle directions.
