Can't find this (at least not definitively) when Googling:

Anyone know how a speaker cone is measured when looking for a replacement? Yes, I'm open to any help from someone who works for (or owns) a speaker manufacturing company and is likely to know the answer fer sher!

Is it the White line measurement (the cone itself)? or...

The Magenta line measurement (including the surround)? or...

The Green Line Measurement (outer mounting ring)?

I have some old Design Acoustics speakers (Audio-Technica) that are no longer made but would be great for my workshop if I replaced the woofers....


TIA!!!
