I have a second setup very similar to what you are proposing, except in a room with a wood suspended floor. My speakers are the paradigm mini monitors which included upgraded to better crossovers by:

The speakers are time-aligned. The high dispersion tweeters make them sound pretty good throughout the room. My goal was to have a system sound good in virtually any part of the room and these fit the bill. I have not heard the non-upgraded Paradigms.
I have measured the Paradigms using the REW software; they are pretty flat down to about 45 hz in my room without the sub (obviously the Paradigms are ported).
Very pleased with these monitors, especially at roughly $700.
