Buttkickers and the like just seem too gimmicky. I have two 18" infinite-baffle
subwoofers mounted in my ceiling (you need to have attic space above for these to work properly). I, too, have a concrete floor in my listening room. Those two subs move such incredible amounts of air that I swear they shake the concrete.
When I watch "U-571" (and well below THX levels, which I find absurdly loud), it feels and sounds like you're in the submarine when the depth charges go off. Reproducing good low frequency is all about moving lots of air and when you move lots of air with quickness and impact, the results are quite impressive, if not startling.
