Make sure you don’t toe them in very much. Focals like to be pointed at 90 degrees to the rear wall, or with minimal toe-in.
The imaging will improve and hopefully you will hear them as less bright and more bass. However, Focals do tend to soak up current in the bass and are not very tolerant of lesser amps. This is not, IMHO a good thing, just experience.
A non-destructive experiment you might also try is to plug the ports and back them up to the wall as much as you can. Make sure to only use clean socks, as dirt and body oils can affect the port refraction. <j/k> but I do actually suggest trying it.
