    Lots of rich folks but also Hotels and bars used these in public areas too. A nice PA system. Hear the boxing match or regatta at your favorite bar.

    Necessity is the mother of invention. War is the mother of necessity.

    OK here's another crack at it. Go to post "InDIYana 2018 dates are official" on this list, and see post 194--there are others but that was the first I came to. This was a speaker actually built by Harry Olson, 15" coax, in a donut shaped enclosure. It sounded remarkably good I thought.

    Obviously that didn't work. I got a message that said the file was corrupted, so I 'll have to try another way of getting it here. I am at work, and that constricts me some. Maybe this evening if I get to it.

    Still has the original tubes.
    Some last a while, some don't. But one of the biggest headaches with early tube computers was the constant tube replacement.

    At Pete's suggestion, I am adding this photo of a speaker system built by Harry Olson (in the 50's I presume) as seen at InDIYana 2018, another quest for the best. It was a 15" coaxial in a unique enclosure, as you can see.

    They had separate amps for mids/highs and lows. It was an ACTIVE multi-way speaker system!!! SQ was definitely a consideration.

    Very impressive, especially for the time, I wonder if there are any left?

    The 30s were a great decade for innovation: radar, television, tape recording and the helicopter, to name but a few inventions, all came from that period.

    Thanks for the link!
