You may want to glue the inside part first and clamp the outside in a few places and test before gluing.
I have tested this adhesive (M-3035 Rubber Adhesive) on scraps of a foam surround glued to a polypropylene bottle.
The adhered foam tears off and leaves the bonded portion on the bottle. The glue can be popped off the bottle cleanly - it does not
soften the polyprolyene but the bond is much stronger than the foam.
I was also concerned with the working time and with a good bead under the foam I was able to push around the foam lip for
several minutes.

Where can I look at this (buy)?
These measurements are spot-on to my measurements. The ones I have in my eBay cart (various sellers) aren't quite right.
If course if it's for a MW-164 it's likely a butyl rubber surround and I'm not sure I can go there.
Automotive spray foam?
Or sticker glue, used for making adhesive sheets (it is spread between top layer and bottom release paper), looks like white wood glue, but smells different and needs screen printing ink solvent, not water soluble.
We used to add a little solvent, otherwise it was too fast for us to work, could be there are different grade.
I used to get half and 1 kilo packs from a shop selling screen printing supplies like ink and so on.

It was a rubber one found on ebay.
I have searched a bit and only sicken shop winking has some foam surrounds for mw 164, no measures disclosed though.
That's what I did. Glued to the cone first, then to the frame. With the glue I recommended, I could move the cone easily on the frame for a while. I just pressed the cone down and released it multiple times while aligning it, ensuring my fingers were spread out, pressing it evenly and listening for scraping.
That said, with these particular woofers it was not difficult to do. I'd imagine some may have tighter VC gaps. The speakers were only Denon low end two ways, intended for practice as I'd always wanted to have a go at surround replacement.
The rubber adhesive came with a surround kit from midwestspeaker on ebay a
year ago. Search "21w54 speaker"
Blue tape works well for temp alignment.
Narrow pieces less than 1/4 inch wide or it will tear the foam when you try to remove it.
