One interesting thing about Lansing Mfg. systems is the choice of multicellular horns thay used. They offered horns in 3 x3, 2 x 6 and 3 x 4. Seems this geometry disappeared with the coming of Altec Lansing. I have never seen one of these on ebay. They must have been quite rare. Anyone have any idea why these were discontinued? Seems like a 2 x 6 horn would be good in wide theaters where an 18 cell horn was not needed.

Hi guys,

The original multicellular horn was designed by Edward Wente of Bell Telephone Laboratories for the Fletcher Horn System of 1933. It was a 16 cell horn, 4 x 4. Two of them were used side by side with the throats crossing in the back, and each driven by a single driver designed by Wente that was later produced commercially as the W.E. 594A.

The Fletcher System was an incredible piece of work, really the inspiration for much of the equipment produced over the past 70 years. It is described in four fascinating U.S. Patents related to the driver and horn designs: #1,992,268, #2,037,187, #1,970,926 and #2,037,185.

Within two years the Shearer team at MGM was hard at work on a practical two way horn system for theatre use, and they were heavily influenced by the Fletcher. One of their innovations was to build multicellular horns with various cell combinations to suit different installation requirements. John Hilliard felt it was important for all high frequencies to originate from a single source (throat) rather than from multiple sources. The Lansing and RCA products resulted from this effort, and many different cell combinations were built, several of which disappeared soon after. In the late 1930s RCA offered 300Hz. multicellulars that were three, four, five and six cells wide and two or three cells high.

Bob Stephens had overseen the design and construction of the multicellular horns at MGM, and he left them soon after to start his company. He produced a large variety of multicellulars over the years, including several that were only one cell high and some that were two high by six wide.

Very interesting history on multicells. Just to show how wrong one can be, this just showed up on ebay
Guess the unusual format multicells survived much later, well into Altec history.

I e-mailed the guy that runs the Klangfilm website and asked him if any Euronor speakers
have survived. He said that as far as he knew,
neither the early ones with the single huge bass driver, or the later ones with 4 bass drivers, have survived.

Bummer.

There were not many made - probably around 100.

He did know of 2 guys in Germany that owned Euronor Junior speaker systems tho.......
