Hello everyone!
I just picked up a pair of Stephens (my first) They are perfect in every way
A pair: a 206 AXA and an "AX"
Only difference one has a HF level control and was built at a later date

These are the really beautiful red and blue 15" co-axials and weigh about 30 or 40 lbs or so I'd guess

Build quality is out of this world Spiders are dead flat and one of these was most likely built in 1954 from what I have managed to find and read!

Woke them up gently as I knew nothing of their history Sounded sort of thin and poorly at first Played them at very low volume for about a day with Sorry State and then hooked them up to my little 6BQ5 tube amp

WOW! These things sound remarkable and just keep getting better as I play them more :bouncy:

Hate to say it but I think they best my 001s in most every way so far

Anyway, one of them has it's surrounded treated with something from the factory and the older one does not It's the damn all paper conundrum like with some 130s The cone doesn't terminate as abruptly and sharply into the roll as my JBLs and appears to be a more ideal form as well as a heavier stock

Does anyone else here own a pair of these? They sound so good in a thoroughly "modern" way that I might even consider these as daily drivers, but I do not wish to harm them

Should I teat the surrounds? Leave as is? I was all set to treat the older one yesterday and had everything all set up but then stopped

The cone is just so pristine and clean! I decided to mull it over some more The other half of my brain was saying; "they are paper, if you use them long enough they will split"

Or will they?

The boxes they came in are very very nice but need bracing or something as the bass is too much for them (by about day 4 you could feel them vibrating like crazy; they are 3/4" veneered plywood) Definitely inspired by JBL's Lustig stuff They are "ported" by a vertical slot cut on each side of the box and the opening is covered with what looks to be nothing more than masonite pegboard for hanging tools They were definitely built in a factory or by a professional operation but there is nothing present to indicate who's

A mint copy (all 3 discs) of Michael Jackson's HIStory vibrated off the top of one and fell to the floor ruining one disc :(

And no wise cracks about listening to M.J. ;)

Any help advice tips or links to more information regarding these would be much appreciated! :bouncy:

Not a whole lot out there that I've been able to find

I read several short pieces in which these were mentioned briefly along with the venerable "604"

I have never heard a "604" but if these are any indication I couldn't imagine And with only about 10-12 watts!

Thanks folks

That's a nice find!

Photos would help enormously; (Please, no cell phone photos!).

There's a photo somewhere out there too of a completed sale of one of these

The seller took the picture with the driver "face down" on a wooden floor :(

What's the problem? I'll tell you :)

The 8 cell horn extends well beyond what is normally the terminal plane of the basket's opening!

There's one on ePay right now posed the same way

Hope these people aren't damaging these beautiful things :(

One of mine is much older than this pair (the "AX") and one is a little newer:

Is there a forum related to single source/high efficiency drivers such as these? The "antiques"?

Plenty of stuff on the modern Fostex and Lowthers etc

Not having much luck with my searches :(

Thank you!

I'd love to know if these would work well on an open baffle before I spend the time and expense to make one up

Could anyone tell me from this? Beyond my abilities :(

Thank you much! :bouncy:

Thomas Hey Thomas, I happened upon a pair of Stephens Tru Sonic 122 AX 12" coaxial drivers. They were in an Acousticraft console I recently bought. The speakers had there own separate Acousticraft enclosures which are really nice cabinets.

I was pleasantly surprised at the warm full sound.... really, really nice.

I found this link on several Stephens systems... http://www.audiovoice-acoustics.com/forum/showthread.php?t=65

There is a one single speaker like mine of EBay for sale right now.... http://cgi.ebay.com/Mint-Stephens-Trusonic-122AX-Speaker-Original-Cabinet-/140512724948?pt=Vintage_Electronics_R2&hash=item20b73607d4

Here are a couple of pics from that auction....
