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!!!

I am not a "fer sher" kind of guy, but I would bet dollars to donuts that any after market drivers will have specs for the drill holes to use as a guideline. If I were buying a replacement cone, I'd look for that spec within a particular cone size and wouldn't rely on the cone size spec as definitive (for the reasons you suggest above).
Now, for someone who's not guessing to chime in...

AFAIK, it's the purple line.

I remember the Design Acoustic speakers rather fondly. I had the PS30 system years ago, I really liked them and wish i would have kept them.
I think Ken is right.

I thought you were just supposed to replace the foam surround part thingy. Not that I've ever actually gone that route myself.

I think that's something you can do, but I haven't a clue how. I know my parents have paid a fair amount of money to have it done on their speakers.

Its a relatively simple procedure, You basically just remove the old surround and glue the new one on. Although you may or may not have to cut off the dust cap and shim the voice coil in the gap otherwise it can become off center and rub. The last time I put new surrounds on a pair of drivers I did not have to do that. Parts express sells refoam kits. They can also help you select a new driver that would work well in your speakers if you did not want to refoam them.

Thanks for the suggestions! I hadn't considered replacing just the foam....but my next round of questions would have been along the lines of "Now how do you pick a replacement driver that won't be 3dB less efficient (and therefore "quieter") than the original", etc... I guess if I just replace the foam, I don't have to worry about driver specs! The Design Acoustics "Point Source" series sounded pretty good. They were relatively deep cabinets with a comparitively small front baffle with the idea of providing needed internal volume with a "near" placement of woofer to tweeter so as to be closer to a "point source" design. I'm impressed with the internals now that I took a driver out. I'm looking for something for my workshop and I was thinking....don't laugh.... about these simply because the two overriding factors are "inexpensive" and "louder than a woodshop". OK, ok. I asked you not to laugh!

How much louder could a woodshop be if a woodshop could shop wood ?
