Your chart is not labeled but that looks like the MMG curve? The 1K Hz@23 Ohm rise did not make my Cary Six-pacs happy. It was discovered during listening tests and in searching for the cause, the impedance curve looked like it might be the problem. Swapping out the tube amp with a solid state device completely cured the issue.
No measurements were taken to confirm my listening experience but it didn't really mater, the issue (problem with one frequency) was identified and resolved. The 3.7 curves look favorable but I have not seen data for the new series crossover and I wanted to try the Six-pacs again.
Worse case, I'll dump the Carys and put my 400WPC Mac with output transformers on the job. Did you have something to add?
