Summary

Description
English: The Lansing Iconic high fidelity loudspeaker from 1937 incorporating its model 808 multicell high frequency horn (top) and model 815 cone woofer. 29 1/2 in. high, 25 1/2 in. wide, 19 1/2 in. deep. It retailed for $300 (equivalent to about $4900 in 2015) and was used in studios and by wealthy audiophiles. The multicell high frequency horn on top is powered by amplifiers in the boxes behind it.

The multicellular horn was invented in 1936 by Edward C. Wente of Western Electric's Electrical Research Products. (ERPI) division as a solution to the problem of high frequency dispersion. Horns were used in speakers because they could produce more sound power than cone speakers, but at high frequencies the sound was emitted in narrow beams, so listeners located off the horn's axis couldn't hear the highs. In the multicell horn, multiple small horns pointed in different directions cover the entire listening area. The form used in the Iconic, the "Shearer horn" was developed in the early 30s for theater sound systems for talking motion pictures by John Hilliard and John Blackburn at Lansing collaborating with Douglas Shearer at MGM.
