Some comments that have come up in a Stereophile review of the Mytek Brooklyn amp and elsewhere led me to search for impedance plots of large speakers.
Some large speakers are hard to drive. I'm thinking electrostatics, pure ribbons (like the old Apogees) and probably many more.
On the other hand, it is possible to make large speakers with multiple drivers that are incredibly easy to drive. Here's a good example, the Dunlavy SC-IV/A as measured by Stereophile:

Best,
