lorenz: 33W; Supercelohet

The rear panel of my Lorenz Supercelohet carries a small triangular logo (kind of road sign; but the border in green), showing a round loudspeaker on a table stand, and the letters C  10 and at the bottom the 3 letters LPU. What does this mean?

What does the name Celohet mean?

LPU means "Lautsprecher Patent Union". In English: loudspeaker patent group. It was a union of loudspeaker producer which aquired the patent rights for the construction of loudspeakers. The construction of a well performing loudspeaker at that time was covered by a lot of different patents of several companies (Telefunken, Rice Kellog etc). So a group of loudspeaker producer was formed which aquired the rights to produce loudspeakers. The sign on the back of the Celohet means that the loudspeaker was produced under the rights of this LPU and the producer is member of the LPU.
