1954 Home-Built Loudspeaker Enclosure

This is a University designed DIY loudspeaker. Today we would certainly add a tweeter. Even in the 50's you could add a Jensen RP302 super tweeter.

Vintage DIY Console And Turntable

This console was built by Jack Hornbeck. We will have another post featuring his work soon. I've seen many DIY consoles but I haven't seen one where the maker goes so far as to designand build  their own turntable and tonearm. This is superb vintage DIY. Top notch.

DIY Large Horn Loudspeaker Hi-Fi News Oct-Nov 1967

This is one of the coolest DIY horn articles I have seen. Thank you Saturn Sound for preserving this information. I wish there were more DIY guys in my area as I would love to tackle this one. My house has 11ft to 12 ft ceilings. This could be a very doable project. I wouldn't do the concrete but the same principle would be interesting. I do not like small speakers so this really hits home for me :)

Mad Genius or Dumbass Design?

You're traveling through another dimension -- a dimension not only of sight and sound but of mind. A journey into a wondrous land whose boundaries are that of imagination. That's a signpost up ahead: your next stop: the Audio Twilight Zone!

A friend that runs a local antique mall said he had something weird. Well the something weird is really weird. This was the creation of a local engineer who designed and built this speaker. It doesn't look like a speaker but that is whats alleged. The base of the cabinet holds a very specific JBL driver which fires up into these tubes. It is said that he tested and measured each tube on test equipment and that it took a long time to build.

I hope some engineers and speaker builders will chime in and give some sort of a clue as to what this is and how they may think it works. Is this the work of a mad genius or a dumbass? I used to know a guy who thought he would become famous for his crossbreed animal farm with critters like the goaticken or the turkduck. Could this be the same kind of misdirection or sheer genius? Please let us know your opinion.

These are speakers I would expect Moondog to have owned.
