I removed these from a set of Vintage 70's Essex speakers model 400. I don't think these are original so I'm asking for help in identifying them from the pictures I attached. There is what looks to be a manufacture number on the magnets if anyone can cross reference it. Thanks for the any info.

It does indeed appear to be the micro acoustics logo.

I am not absolutely sure that the number on the speaker 433651 is an EIA manufacturer/date code*... but if it is, "433" is the EIA code for Cleveland.

* Earlier EIA codes contained three-digit date codes, but I'd have expected ma woofers to be new enough to have four digit date codes.
