I am running two LK140's aktiv into Ninkas and previously ran only one passively. I never tune demed the LK140 to the LK85, because I wanted as much power as I could afford when running passively and the Klout was a little out of my reach.
I too have heard numerous times if you run aktiv LK140 and LK85, put the LK140 on treble and LK85 on the bass for the same reason you stated. I thought about doing this when I went aktiv, but instead just saved a little longer to get a matching LK140.
