ABSTRACT:
A loud speaker enclosure is disclosed in the preferred and illustrated embodiment. In this form, the upper end of the loud speaker enclosure is shaped in the form of an oval having a relatively narrow opening in one dimension which opening is relatively long in the other dimension. It is surrounded by an encircling shoulder which serves as a mounting plate. The housing flares downwardly and to a larger diameter matching that of a circle so that it can be connected to a speaker. Preferably, the circular end of the housing connects with the outer rim of a bass speaker. The shoulder at the oval end supports a tweeter. The shoulder is connected to the nether side of a package shelf, and the housing extends below the package shelf where greater room is obtained, enabling the larger woofer to be mounted with greater space for it.
