Brad, you are accurate and insightful as always. Only statement I disagree with is the imaging part. It is independent of back boxes, as it is strictly a tweeter function.
No,
Imaging is a product of most all of the audio frequency. We take spatial cues from quite a large response. The bottom end of that is a topic of controversy, with most arguing in the range of 70-120Hz.
But certainly response differences in the 120-260Hz range (on average) can make a slight difference in imaging as well. Those frequencies can certainly be affected by enclosure volume.
