ABSTRACT:
A hermetically sealed speaker enclosure assembled from pieces that can be shipped economically in compact knocked-down condition. The mating surfaces at the edges and margins of the assembled pieces are hermetically sealed by gaskets clamped therebetween. Some of the gaskets can be in the form of bands of compressible elastic material stretched around the peripheral edges of certain pieces or panels and seated in connecting grooves in the peripheral edges. Other of the gaskets are in the form of individual lengths of compressible material seated in certain of the borders or marginal edges. Appropriate fasteners are used to secure the pieces together in hermetically sealed relationship. Assembly of the speaker enclosure can be economically made at the place of installation of the speaker components.
