So you did get them? If so, then pull the screen off the baffle and pull the drivers. My suspicion is the drivers are vintage OEM types made by CTS or similar, nothing wrong with that, but the speakers are either DIY or made to a price point for a stereo store chain as an in-house brand.
They could sound decent, but the crossover is likely 4 components or less, even for a 3 way.
Technically, if the boxes are solid, there's an opportunity to DIY build something that could sound really good if that is a potential project goal. Of course, that runs into some $$$.
