Hello everyone, I happened to pick up 4 of these puppies for a good price, but the seller had no info on them or manufacturer . I think I see a bucking magnet and they have a sheilding cap over the whole assembly. The (metallic)?? Dome has a geomertric pattern , I guess for strength or some other purpose. On the back of the magnet assembly it says:

58P60DH-01HD
C5. WAVE
Made in Japan
562TNV

Weird thing is the absense of a front plate???
Any help you can give will be appreciated

I'm pretty sure they are the high frequency transducers from a JBL Pro VIII two way cabinet. There's normally a mesh screen that fits over the front of them.

An externally hosted image should be here but it was not working when we last tested it.

Yes, JBL. I had a few of those thru here.

The part number stamped at the back of the driver (58P60DH-01HD) is the same as the one in the picture.

Thanks for the help identifying them.They sound nice , I wonder if they would work in a waveguide,perhaps made from bent wood?
Ill see if I can find specs for them, if not i'll take some measurements. Does anyone know if the ribs on the cone are there to control diaphragm break-up?
