A friend of mine picked up one of these but his isn't the field coil horn but he has the field coil woofer..Some were made with both or one or the other..This is just the AM radio playing but when you hear these units with a CD player or a modern turntable and cartridge,you will be amazed..These use the Stevens Trusonic horn.I wish I had two of these horns and two of these woofers with field coils on both.

That's what I always thought..I would be the ultimate authority on papa goosises and mama goosises and baby goosises.

they sound a bit "honky" to me even via Youtube through my in-ceiling office speakers. :)

You are hearing it thru the AM radio over youtube..If you heard they drivers properly mounted in a bass cabinet and driven with a good EL84 or 6L6 amp,they are quite impressive in real life.

Perhaps. While both are bandwidth limited, the coloration to which I refer is a decided hollowness in the midrange.
Indeed, there is no top end to be heard.

..If you heard it in real life which I have but not on that old Magnavox amp,the hollowness was non existent and the high end was plentiful and it wasn't colored..Of course the woofers were built into special cabinets and the horn had dampening material added in parts of the horn where ringing existed under high dynamics.The way we hear it in the youtube video is nothing like hearing it properly set up..I like the same type of sound you do and believe me,you would be shocked at what those old drivers are capable of..
Wood horns are much better than metal horns but you if you dampen the metal horn,it becomes a totally different animal..Even tho the freq response doesn't go out as high as a stand alone tweeter on measurement,the efficiency and the way the music is delivered allows us to hear all that human ear is capable of even it only goes out to 16khz.

Surely a live audition of a complete system would sound better.
Just for grins, here's a quick iPhone video of the garage system using a similar walk-around-it approach. :)

That Stephen's horn actually has tar in between the metal casting.

Was that previously in one cabinet?
A friend has been collecting Stephens multicell horns drivers and woofers. This year we finally got around to listening to them atop khorns and they are superb.
High sensitivity, wide dynamic range, low distortion, and smooth frequency response. Pwk
If better or competitive than what you can buy today in speakers, why doesn't someone go into production of a product based on those original designs?Mikey, do they actually sound better or just competitive or different?

They do make field coil drivers today, but they are extremely expensive. When these drivers were made, fixed magnets were not powerful enough to work well so they had to use field coils. For most people (including me) a fixed ferrite, neodymium, or alnico magnet will do, but if you are a perfectionist ...

The field coil drivers sound very very good when properly setup..They are extremely fast which translates to very low distortion and a lot people have compared a good field coil driver system by calling it a Quad ESL on Steroids...When you get a chance,go see John at classic audio reproductions and listen to the 68k dollar field coil speaker system he builds and sells.
He runs it on the Atmaspheres but it is one of the top three systems I have ever heard in my life.

I think one problem is, and I saw this discussed, I believe, on ARF, that one major difference is that professional gear is made to a standard that MUST be measurable and to an engineering standard, whereas commercial/consumer gear is not. And add in that current corporate is much more interested in money that quality and therefore finding some company to reproduce the same quality from 60+ years ago, when companies DID care about quality, makes the endeavor even more difficult. I guess that is why there are a number of people using old parts to build new audio products and/or the revival of vintage gear that seems to be of so much interest...
I don't know. Most drivers today are made for higher power handling. Not sure how much of a difference this makes.
