Nice project Grant! Now, go thump 'em and see what ya' got!

Those moments when you find a better way are sweet, nice one man

I didn't have to cut the baffle out for the last 2 cabs.
I found these circular 60 grit flap disks, which let me enlarge the driver spacing without removing the baffle.

I've always wondered if there is a router template bit that cuts, say 1/16" more with a bearing guide. Then you could use the existing hole, make it 1/16" bigger, then flush cut the other 1/16" out with a normal flush cut bit. Rinse, repeat to go larger 1/8" on the diameter at a time...

I like the flapper wheels though, I might pick some of those up just in case...

That's why 3d printers are so great. You can design and print a baffle router template in a few hours and it'll fit perfect. That's what I did recently to replace the driver in my AT. You can't fit a router in the chamber, but I was able to make a new baffle and mount it to the existing baffle.

Most valuable tool man. Just like a 10mm socket. Or that digital angle guide I keep telling you to pick up

My old makita router has a follower that screws into the bottom of the baseplate. It requires adding about 1/16" for the template cutout to end up with the workpiece the right size. You can also get router bits with the roller bearing at the top (I think it's called a follower bit) to route to correct size with the correct template.

The issue was depth though. Setting up the template with enough clearance to clear the Panel 6 extension (and the same for height for the upper part of the template to baffle height to maintain the correct angle) means a 2" bit just isn't long enough for all the required routing. It might do the driver one, but not the anchor part. While 3" bits are available, it would have taken weeks for one to turn up in the mail. Do get those flappers though. 1 is 1/2", the other 1"...

My ply templates work fine
Still, you can 3D print yours, so you should!

I can't imagine doing what you did for your AT working in a T39 though, unless you also took a slice out of the top of the chamber.
No bid deal I guess, since that's how they use to be made, but I was trying to minimise potential leak spots...

I just appreciate the ingenuity and abstract thinking people come up with

Oh I made sure it wasn't gonna leak. Plenty of PL and screws to keep the baffle to baffle surface airtight. And some decorative schmooing along the edges a la bathroom caulking style. It's a band-aid fix and if I ever blow another driver I'll probably retire the cab and built another, but bigger to house these Infinity 10's I have.

Ah Roger, I've lost all my 10mm sockets, and if I need an angle guide, I'll pop over and borrow/lose yours mate!

Absolutely

Haha, welcome any time!
