I did something like that with Easel for the x-carve. It worked well for the SB polymer frames. The most problematic driver I've tried to countersink is that 5x8 SB Acoustics Oval woofer. It has a stamped frame and the sides flare out a little, but not uniformly.
Keep an open mind, but don't let your brain fall out.
For the "racetrack" woofers I drew it manually and it worked out pretty good. Stamped frames can be a pain but cast frames are often not as round as we would like them to be eather.

Yep, it took a few test cuts to get the racetrack PR rebates dialed in before cutting the final.
I surface mounted the 5x8PR in the Purveyor, but drawing the through hole was more difficult than planned. Only after did I find the cardboard piece in the box that I could have used for it.
He thinks he has a set of 5-1/4 series 1 somewhere. Hopefully we can find and use those. I’ll have to modify the tweeters as the coils are frozen in ferrofluid.
Hmm so a shallow mid enclosure is a thing. I have been daydreaming of a similar design layout for an isobaric 3-way to take a woofer that likes alot of box volume and shoehorn it into a bookshelf. But I dismissed it figuring that the close back wall would be tough to work with for the mid since the space to damp the backwave reflection is so limited.
I've had a mid chamber as shallow as 4". That's about as shallow as I'd go. It allows two layers of 1" thick damping material with the magnet just touching. I like to use two different densities for the damping. Usually 1" open cell foam and 1" Ultra-touch.
Shallow mid chamber, but the mid will be crossed over pertty high to the isobaric woofers and the mid chamber will have foam on the back wall and suffed with ultra touch and polyfill cradling the mid cone. In acual listening at normal volume, shouldn't be too bad.

Pretty nice drivers. Simple but built well.

Wavecor with a stamped steel frame? Cone looks nice.
It has a very nice rear gasket on it too . . .
If you decide to carry those, do you know what your retail price would be?

Wow - I hadn't looked at the Speakers page in a few weeks. That's a good assortment.
Been working on some flush mounting jigs.

A little loose for veneer but great for primer filler and paint.

On this one, I think I took the shape from the data sheet, used Convertieo to make the jpeg into an SVG then into V-carve.

I draw all mine out on the software. This SB is pretty simple shapes.

A friend of mine wishful thinking. Monkey coffin.
18”,8”and tweeter. The 8” is not gonna make the cut.

Man, I forgot how much I like those old Series 1 subs. Cool stuff!
Could you save the dust cap from the 8 and mount it on the mid-woofer you choose? might be a way to keep the look but not the driver.
Back in about 1989 I had a pair of RF Punch 10". They were before the Series 1. They were cheap but boy did they slam!
Hell yeah!!

How many cubes to make those 18s sing?
Haven’t got that far yet. They dats fine but I’ll run some low end sweeps on them to make sure they don’t rattle

Don't you dare mutilate those 8" lol
The terminal plates got pushed out to the first of the year. Boo.

Isobaric [dual] reflex?
That is what it looks like to me.

The cabs are looking good, Brad!
