I picked this up at auction this weekend. No markings I can find anywhere. It is 8" with 12 Ohm impedance. Looks similar to Altec with paint color and shape too me. Unfortunately it appears to have been reconed, which could have been a clue. Any thoughts?

If you measured 12 ohms with an ohmmeter, treat it as a 16 ohm speaker. The meter will always read lower than the true impedance.

Is there a number on the back of the cone? If there is, and it starts with "WHF" or "HF", then it's been reconed (Waldom parts). I ask that, because that looks like a cone that Waldom frequently supplied in the past...

EDIT: The color just makes me think Ampex, for some reason. Though I can't remember seeing anything that looked exactly like that from Ampex...

Regards,
Gordon.
