No idea what these are. DCR around ~4ohms. Looks like there was black writing on the magnets that has since worn off. "Made in England" on the back side of the mounting bracket. Thanks in advance for the help!

Looks like Celestion hf1300 drivers to me, but minus the kind of 'phase plug' or 'dispersion plug' in front of the diaphragms. Check out the Celestion hf1300 and you'll see the 'phase plug' I'm referring to.
 
Awesome, that looks to be spot on! Thanks! Gonna try to hunt down a frequency response chart for them - mainly worried about between 3kHz and 7kHz.
 
As far as I can remember they are pretty good but don't go much above 10-12khz, may be thinking of a different driver though :D
They were used in some fairly high quality B&W, Spendor, Rogers, and a few other well regarded speakers, but commonly supported/supplemented with a Coles supertweeter.
 
Thanks - I'm looking at the Spendor BC-1 freq. chart now, looks pretty solid in that range, and they were crossed at 3kHz and 13kHz it seems.
