The "more compact for home use" almost look Seussian. Who says Jubilees are too big for the living room Ha! They look pretty small compared to these behemoths, whic I do like by the way. Now who said Jubilees have a low WAF? So honey, it breaks my heart, but if I can't have these, what about these puny liitle things ....

Per an Internet translator:

?Klangfilm?'s then technical manager H. Warncke made a journey to U at one time. S. A. and attended the performance in a large cinema, who also had a cinema organ. When the cinema organ ended its responsibility, and the sound movie started to, the reproduction from the theatre's large combination loudspeaker worked like a cold shower, compared with the cinema organ's enormous and clean metric ton register. The loudspeaker construction's flaws were evident, and manager Warncke decided that he, would construct without regard to the expense, a loudspeaker, which sound-wisely could compete with a cinema organ.

In 1938 appeared the construction, called ?Euronor?, and the fulfilled one all expectations. It had 4 paragraph 2 meters long 3 celled treble horns, as well as a bass loudspeaker of so far unknown dimensions. Its high price was the reason why they again thought that there will would be sold a small number of them It remained to be seen however that the quality jump was so large that also it became a real success. In consequence of its unusually large material consumption, the manufacture was still stopped, when the 2. World War started.

[The real problem was that it was not available in walnut.]

The company Klangfilm (sound film) made systems(pre- poweramps and speakers) for movie theaters. It was started in 1928 and was then taken over in 1941 by Siemens. There office was in Emmendingen/Baden, under Stutgart near the boarder to Switzerland.

Thats probably where they got their horn form idea. [;)]

Something more compact for home use:

These all look like Ale products from Japan with exception of the mid range wood horns. They look like they're from Sierra Brooks in the Phillipines. Those Ale products are pretty pricey, right up there with Gotto drivers. Ale makes and sells a wide range of compression drivers and all those big horns seen here.

I did a little scaling of the photo of the bass horn and some math. All results are approximations because of rough scaling.

The horn has an Fc of 26 Hz. The equivalent mouth circumfrence is 83% of the cut-off wavelength.

Those numbers make some sense.
