The backstory: I have 2 E53’s in the driveway. One is the wife’s with the basic stereo. The other is a flip car with the navigation premium sound but the head unit is broken. Depending on complexity I might put the wife’s basic stereo in the flip car and do an android upgrade in hers. But are the speakers/drivers different?

You would have a lot of rewiring to do as well. The harnesses are completely different. As for the actual drivers, I believe the base sound speakers are 4ohm while the DSP speakers are a mix of 3ohm and something else. I have a complete set of DSP speakers on a rack, could check resistance. But again, pretty sure a lot of wiring to fit the DSP amp and radio unit in the back would be needed.
Now, if the nav truck has premium sound. The radio module is still located in the trunk but I don't know what impedance those speakers are. I'm pretty even the premium sound amp has more channels of amplification than the base audio vehicles though. You might want to check below to see just how much work would be needed given the differences.
