To pull this off, you need a tweeter that is really a mid-tweet that plays really really low plus a paper-cone woofer that plays really really high and then just smoothly rolls off without getting bumpy. Basically, no poly-cone woofer does this.
This is a much easier feat with a 10-inch woofer than a 12-inch woofer. That Seas woofer Madisound carries is a 10 incher that comes close to doing this, and there is a Tweeter that goes low as well. Airtime has all the details. The modern version of the Dynaco A20 is the relatively easy 2-way build, but that is a 10-inch woofer.
So far as I am aware, there is no currently-manufactured reasonably-priced 12-inch woofers that would work in a 2-way design. You are looking at using vintage paper-cone woofers from companies such as Jensen or Utah. These sometimes show up on ebay. Trusonic in later years was part of Utah, and I think a lot of Trusonic speakers prior to that used Utah-sourced drivers. If you measure the original large Advent woofer the right (wrong) way you MIGHT conclude its a 12 incher...its really a 10 inch woofer in a 12-inch frame. And the tweet ie really a mid-tweet, a mid range and tweeter in a single frame. The tricky part in a two-way large woofer design is getting the lower mids right in the transitiona area between the woofer and the tweeter. Even the large Advent didn't get this perfectly.
