Driver driving a passive raditor with internal port in seal encolure

I think we have discussed before but lost the thread
What kind of speaker design is this

That's a series-tuned 6th order bandpass, with a passive radiator as the 2nd port.

The tweeter chamber seems to have a short, wide port too. Might it be an 8th order?

I think that is the closed midrange chamber. The wide port thingy could be a plate to feed through the speaker wire. It is an Elac Adante.
