摘要

An earthenware pipe is mfd. by conventional shaping and firing processes so as to form a cabinet free from adhesively bonded, nailed or screwed joints. Covers are applied to its upper and lower ends (2.1, 2.2). The loudspeakers are fitted into apertures in the bed of a shallow recess (2.3) in the curved surface. The covers and loudspeaker fixtures are mfd. of the same material as the pipe and fired together with it after the completion of the shaping process. ADVANTAGE - High tonal quality requirements are satisfied by a simple and inexpensively mfd. cabinet.
