If you want bass slam, get a sub-sat setup and spend less on the main speaker. (Think Paradigm signature bookshelfs with their 15" servo sub.) Your amp would be fine for now with these.
I have Thiel CS6s which go flat down to 28htz or so. I would not descibe them as capable of big slam without a sub even with my McCormack DNA-2 DLX amp which is 300 watts at 8ohm.
