Repurposing old car speakers - Ideas???

[Nemus]

I have a set of pioneer 8 inch 3 way speakers. Had them for probably close to 20 years in various vehicles, taken care of them when installed and between installs. My current vehicles do not have space for these and I would not cut to install these speakers into them, so I had them in one of those twin 8” boxes, but I’m looking to repurpose them.. has anyone done something similar?
Does anyone know where I can find a pair of decent towers or bookshelf enclosures to install them?

Or maybe install them in the ceiling??

Maybe an enclosure like this???
Where would I find this?

The square part, maybe.. but that labyrinth port would be out of my woodworking skill level.. would be amazing to have one of those boxes.
