Yes they are wonderful speakers. And that’s why I can’t part with them. In my opinion the current version,
( legacy Focus SE ) I’m quite confident at the price point there are few loudspeakers that could compete with these speakers. 
Any feedback on legacy speakers would be interesting.
I would have to add that dealing with Bill Dudlesten and his wife Victoria has been a absolutely wonderful experience.There are very few people in your lifetime you will meet like Bill and Victoria...
I tried various settings.  A bit over 400 seems the best in my system.  Some people seem to like it at 1000 though.
