Voigt 4ft Tractrix Horn

People talk of Western Electric being rare but no these 4ft Voigt Tractrix horns are extremely rare. Likely only a handful of the big fellas exist. I only see ads of people looking for them and a few pictures of them on the internet. These look incredible.  


I would like to try this approach some day. This reminds me of what Dave Slagle of Intact Audio does with Lowther drivers and big round Le Cleach horns.

  4. Thanks for posting - Paul Voigt's Tractrix cinema Horns (field coil of course) date from the 1930s-40s.

    I had a go at a round Voigt Tractrix horn - but in fibreglass - the story of these is here...https://darklanternforowen.wordpress.com/2014/04/13/tractrix-midrange-horn/

    Cheers, Owen

  5. Cheers Iain - Note how on Voigt's 4' square cinema horn, he had an L-shaped 'Bass Chamber' attached under the driver, in order to extend LF response. Not exactly the same thing but that's maybe 50yrs before Bruce Edgar experimented with Reactance Annuling on his bass horns.

    1. Bruce Edgar was quite the Voigt historian so it is not so surprising. I'd love to hear one of these some day.
