$200 (US) seems a little excessive to lengthen the port, IMO

It could be more complicated than that. Generally you also want to increase cabinet volume as you lower tune, so maybe they found a way to do that.

There are two rotary subs that I know of, only one of which, the Thigpin, is still in produciton. I would love to hear this one in action as it is supposed to be in a category by itself.
