It is indeed odd.
The case is of an early version Duetta (with the lip at the bottom front) but the Terminal clearly says Signature which is the latest iteration...
It's not that odd they did upgrade Duetta IIs to DS status. That's all these are I am pretty sure.
The magnets in Apogees aren't that strong and even in the day they weren't. But caution is advised especially if the grilles are off. Then you really do need to be VERY VERY careful. Just one moment of stupidity and you are in trouble with a damaged speaker.
Anyway, if you haven't connected them up, it looks like you have some cable that might do it. The stuff I have marked in red on the attached pic.
For each speaker, connect the bass black and red and tweeter black and red terminals to the spades at the end of the cable with four connectors. The black and red of one pair of spades to the black and red of the speaker connectors e.g. bass and then the same for the treble, matching the colours.
Then connect the end of the cable with the two spades to the left or right channel of the power amp, matching the colours. Colour matching is VERY important, or the speakers will be out of phase.
That's for normal bi-wire cable however it looks like you may not have normal bi-ware cable, but four pairs of connectors, two at each end? If so say so if you are confused?
