"What do you think about the second sub idea?
I know this isnt what you want to hear but, in my experience, subs are one of those personal preference sort of things. Some love em, some dont. If I added subs in my system, Id probably want to make use of some room acoustical measurements software. Have you talked to your dealer about letting you try both options in your space?
I still think that the 2.5 meter listening distance is likely to prove problematic for the Scalas.
