I've recently obtained a pair of fullrange 5 in RCA ---{or more correctly unlabled RCAs}--- that were used by the US Military. These are actually very heavy, phenolic drivers that I found to be very interesting looking (see photo) Does anyone have any info on these drivers? Are they as good sounding as they are reputed to be? Any input would be appreciated.
My friend is sending me a pair of his own DIY design enclosures called the Angel. They're a corner horn loaded enclosure and I'm getting them for FREE out of Canada for me to try these drivers in. Of course we both realise it will be hit or miss but, at least it's a starting place....

Well they certainly have a basket that i have also seen on Asian drivers i usually attribute to Coral -- what are the numbers on the driver?

Phenol is a powerful anti-fungal -- pretty good for a simple benzene ring with a hydroxyl attached. Phenolic resins seem to have some antifungal properties surviving the process whereby they are turned into a thermal setting plastic.

Dave, they might well not be RCAs. I only know they were sold to me as fullrange drivers and look just like the fullrange RCAs drivers I've seen on eBay ---{at least from the front that is}--- I'm at work right now, so when I get home tonight I'll post the numbers that are on the back of the magnets.
Oh another note I should be sending you those FE206ES-R's soon for you to work your magic on them.

Dave I had a horrible migraine last night so I didn't get around to getting the #s off the back of the drivers like I said I would.
Tonight I'm feeling much better so here's the #s I said I get for you. There are actually 2 different #s on each driver. On the top row is the # H306 and on the row just below it the # is: 575219. Both drivers are marked exactly the same way, with the same #s.
If these #s reveal anything about the driver's manufacturer please let me know who actually makes them, ok? Thanks Dave I appreciate your help.

Made by Hepner, the 21st week of 1969 (or less likely 1959)

I'd say it's much more likely that it was 1959, though 1969 may be more likely still 🙂

Typo and dislexia... GM is right, here is what i use: http://www.planet10-hifi.com/EIA-SpeakerCodes.html so probably made in 1962.

OK, I was beginning to wonder since recently on another forum an otherwise valid date code ended in '53', implying the 53rd week of a 52 week year........
