Don't those founder series also have the room correction built in?
if its the same ones i was listening to a couple weeks ago they are very good, I liked them better than the Focal Sopra 2's I also listened to.
The room correction system integrates the bass much better than any sub alone will. It only works on the bass section but after we took the measurements and let the software do its thing it smoothed out the bass response significantly in the smallish listening room at the dealer. made me stand up and consider them more seriously.
