LARGEST LOUDSPEAKER HORN FOR AUDITORIUM (Dec, 1930)
LARGEST LOUDSPEAKER HORN FOR AUDITORIUM
Designed for use in auditoriums, the biggest loudspeaker horn yet made has recently appeared on the market. Its twelve-foot opening gives it the appearance of the entrance to a tunnel into which an automobile could be driven. The claim is made for it that it will reen-force notes down to twenty-five vibrations a second and project it with no appreciable loss of tone quality, to the farthest corners of a large concert hall.
