What is your design criteria (maximum SPL, lowest bass frequency, etc.)? How many channels/subs are you considering? What is your overall budget and budget for speakers? Being an all concrete space recommend your budget include at least $2k for acoustical treatments (suggest GIK here at Audio Circle for products and advice).
As I mentioned elsewhere the JBL 4722 are beasts, way overkill for this application.
Have you looked into more ordinary HT speakers that are part of a family of speakers, so you can have speakers specifically designed for front, center, rear, and height effects channel use so that all the speakers would share similar voicing? Depending on your budget I'd look into SVS, Hsu, Paradigm, or Ascend Acoustics. These companies also offer subs.
