Commercial Speakers
Arthur Janszen was granted U.S. Patent 2,631,196 in 1953 for an electrostatic loudspeaker. The developers of the Tri-Ergon sound-on-film sound film system had developed a primitive design of electrostatic loudspeaker as early as 1919. Mr. Janszen's company, JansZen still makes an evolved version of his original design. The KLH Nine was designed in the mid-1950s by Arthur A. Janszen, and thousands were sold after the design was brought over to KLH in 1959 and put into regular production.

Famous quotes containing the words commercial and/or speakers:
“The commercial class has always mistrusted verbal brilliancy and wit, deeming such qualities, perhaps with some justice, frivolous and unprofitable.”
—Dorothy Nevill (1826–1913)
“The most striking aspect of linguistic competence is what we may call the ‘creativity of language,’ that is, the speaker’s ability to produce new sentences, sentences that are immediately understood by other speakers although they bear no physical resemblance to sentences which are ‘familiar.’”
—Noam Chomsky (b. 1928)
