You are probably right, but it will have to live with a smaller volume for now...
8 cu ft is what the 4645/B460 gives to the 2245, and that is also the size of the "small" box in the 1983 article. With a low tuning and some eq (which I hope I can add with small group delay penalty using the PC) it seems quite good.
I also read this thread:

2245 in a sealed enclosures could well be what I need for my room, and a 8 cu ft volume would let me try both ported/sealed design. If it fails then I could build a bigger box, keeping the unchanged HF panel.
This will be the first box I build, maybe I am crazy to begin with such a big box
