"History

The 1925 paper of Chester W. Rice and Edward W. Kellogg, fueled by advances in radio and electronics, increased interest in direct radiator loudspeakers. In 1930, A. J. Thuras of Bell Labs patented (US Patent No. 186917 his "Sound Translating Device" (essentially a vented box) which was evidence of the interest in many types of enclosure design at the time.

Progress on loudspeaker enclosure design and analysis using acoustic analogous circuits by academic acousticians like Harry F. Olson continued until 1954 when Leo L. Beranek of the Massachusetts Institute of Technology published "Acoustics", a book summarizing and extending the electroacoustics of the era. J. F. Novak used novel simplifying assumptions in an analysis in a 1959 paper (which also established their applicability by measurements) which led to a practical solution for the response of a given loudspeaker in a box. In 1961, leaning heavily on Novak`s work, A. N. Thiele described a series of "alignments" (ie, enclosure designs based on electrical filter theory with well-characterized behavior, including frequency response, power handling, cone excursion, etc) in a publication in an Australian Journal. This paper remained relatively unknown outside Australia until it was re-published in the Journal of the Audio Engineering Society in 1971.

Many others continued to develop various aspects of loudspeaker enclosure design in the 1960`s and early 1970`s. From 1968-1972 J. E. Benson published three articles in an Australian journal that thoroughly analyzed sealed, vented and passive radiator designs. Beginning in June 1972, Richard Small published a series of very influential articles in the Journal of the Audio Engineering Society restating and extending Thiele`s work. These articles were also originally published in Australia, where he had attended graduate school, and where his thesis supervisor was J.E. Benson."

Безсумнівно великий внесок у дослідження акустики Тіля і Смола набув широкого застосування 60-70-их роках... На той час вже давненько існували і 307-і і 405-і і Алтеків і Танноїв було вже, не говорячи про ВЕ 750... Та і оформлень не бракувало і 555 ВЕ і Біонор, правда, рупорних більше, а параметри Т/С більше відносяться до "ящиків"... Як жеж вони без параметрів Т/С нарубали стільки акустики? Мабуть профани...
