If you're so committed to marrying these things, what's
wrong with the idea of taking two forms of somewhat different
diameter and filling the space between them with sand?

Is that what you would do?

The reason such silliness is not necessary is that Sonotubes are audibly
plenty stiff enough. Refer to Hsu and SVS's use for their commercial subs.
If somebody is paranoid about what a Sonotube will do when trying to get
down to really low frequencies, they should just build a clone of the Hsu
TN1220 or one of the bigger SVS models. That way, they will be taking
advantage of research done by people who know what they are doing.
