Interchangeable drivers in popular full range speaker plans

This topic crossed my mind recently since I picked up a pair of unused L Cao 8 inch in the swap meet for peanuts.

Not sure what I’ll do with them, but I couldn’t resist!

I could throw them on a baffle and use them with bass support etc

I’ve only superficially poked around looking for something besides the TQWT suggested box plans

that came with them. There’s also some parts for a suggested correction network.
