Chris,
copying and pasting worked like a champ! :emoji_thumbsup:
Scenario one would be my choice. If your drawing is to scale, it looks like 28" to 30" stands might work well for you.
Chris,
I think you might get some mixed opinions about this....
There was a thread (last week?) that talked, a bit heated at times, about this very subject. You might want to run a search for "speaker height".
IMHO I like the "tweeter at ear level" scenario. Just above ear level has worked...
