A review; in German but look at the plots. Another site showed closed box as small as 33 liters might work. I would probably say that is on the small side.

This is a handy calc; you can compare "ideal" to custom closed box sizes
Do you have a maximum budget in mind here? SS Rev. is pricey but worth it. I had also read elsewhere the newer SB Satori 9 1/2 inch had a similar sound characteristic to my SB29; great lower bass but mid and upper bass aren't suitable for a 2-way.
I'm very curious what you end up with and how it turns out...again; best of luck!

I always wondered what an Advent 3way might sound like...ie: put a time period correct midrange such as the Philips 5060ad in the middle (400hz-2500hz).
Seas A26 10" 2-way Kit Pair (based on the classic A25)
A 10 inch 2-way with a lot of very happy people. NOT an Advent clone for sure but this kit has a large following.
Even if you want to stick more with the traditional Advent design type; read what these reviews say about this 1.5 inch mid/tweeter.

"This classic paper cone has a smooth response with wonderful roll off at 2000Hz. This is one of the only 10" drivers we know of that can be used in a 2-way by letting the woofer run full range without a crossover."

The bass here may not be deep enough???; (I didn't try to do a calc if using your own custom design/size closed box).
(Overall though probably a very good 10 inch woofer choice for a 2-way unless the bass just go deep enough for you!??)

It is a PIA but is a very effective damper.
Of course with those large baskets ADVENT had a lot of basket to damp but they used the stuff on the tweeters, also.
I have been tempted to use the foams but i worry they will compress to the point of leaking.
Never had a MORTITE seal leak but then I might be lucky.
For someone wanting to make a NEW ADVENT the giant woofer basket will not be a concern since there is nothing like that on the market.
I had a double pair in my early twenties after discovering the ABSOLUTE SOUND in my local ADVENT dealer. John Coolidge was friends of the owner and had left a copy of the first issue.
I certainly wish I had never seen it since it did nothing less than inflame my youthful passions for audio that did nothing much more than allow me to waste lots of money!
But it was fun. And still is!
That's a good looking choice that ought to mate well with a 10" woofer. Thanks for the link.
For years I ran the big Scanspeak soft dome tweeters seen here:
Scanspeak Classic D3806/8200-00, 1.5" Tweeter
They are an excellent match with 10" woofers, their tonality seems to blend perfectly with a 10. But used them with a 12" woofer in a large sealed box and they worked beautifully. Sounded great as a big two way speaker in a very large space. These brutes were always expensive, but the price now would make be think twice - if at all.

It might sound the same but the AMAZON woofer certainly does not look like an ADVENT woofer.
I had forgot that DAHLQUIST used the same woofer. Well same basket if not cone.

The Simply Speakers site says it is the same; except the magnet is round. My Advent magnet was square. Some "improvements"??? Perhaps the foam surround is a better hybrid/composite that lasts longer. The newer Advent woofer didn't look the same as the original Advent. I had the "newer" Advent. It had a pin cushion stamped steel frame but no masonite. I'm having fun going to the various sites and reading about the history of AR, KLH, Advent, etc.

Just found this. Henry Kloss needed a way to get funding for his projection TV; that is when he decided to do the original Advent speaker. Interesting history. (He is the "K" in KLH for those of you that didn't already know that).

This is the Satori I mentioned earlier; I had read from a few others that the mid and upper bass weren't that good compared to the low bass; I have the same issue with my SB29. Probably no issue in a 3-way; probably not the best choice for a 2-way. (I haven't heard them for myself though).
I have a pair of Large Advent Masonite woofers that I am thinking of combining in a floor-standing enclosure with a 2” HiVi dome, and a 19mm SB acoustics tweeter, both of which are also already “in-hand”. I have worked out a pretty shape for the front baffle that is nicer than a rectangular box; a shape I have already used for an open baffle. It is tall-ish, and wide halfway up, but still feels nice in my room.
I agree about the lack of midrange definition in the SB NRXS woofers. I used the SB AcousticsSB23NRXS45-4 in a build that was intended to be a 3way, but ended up being a 4-way because I did not like the muted sound of the SB NRXS mids, even when crossed to a dedicated mid at 500hz. I ended up using a 6.5” Silver flute from 120-500hz in a stuffed, sealed, tapered trans-line, which really warmed up the bass and lower mids. I should say that I like warm low-mids more than many audiophiles seem to.This 4-way ended up having pretty high output capabilities. With added low end help they can fill a very large room.

I had the woofers of my HPM900s refoamed after they wore out. New foam is much stiffer but it didn't affect the bass much if at all. A 2.2 OHM series resistor smoothed the bass out.
Maybe the compliance and Fs is mostly controlled by the spider? Was the 2.2ohms in series with only the woofer?
Funny that you should mention the HPM's. I have a pair of HPM700 whose woofers are just bare frames, no VC/cone. I've not been able to find any re-cone options. Seem to have VC slightly under 2". Have HPM60 woofers installed now, nice tonality, but the bass is a little weak---like they need some baffle step compensation. Would probably work OK against a wall as is. Mostly listen to my various DIY builds.
