Concrete floors are good...an un-like surface area in relation to whats usually up top...drywall ceiling.
Concrete also offers much better isolation from vibration of components caused by deep bass, or people... (kids).
Carpet or wood flooring over concrete is probably a toss up...carpet has no effect on "deep bass" although carpet or a few rugs over wood floors does tame reflections of higher freqs so is usefull.
Trying to build a floor thats a bass trap would seem a very costly undertaking...ie, a floor with flex...but still solid. Building better walls and ceiling would be a better investment of your money...double wall construction comes to mind as one thing.
My floor...Concrete. I took treated 2x4's and laid them on their side...glued and nailed down with 24" spacing between rows...this raised the floor 1 1/2 inches.
I placed 24" wide and 1 1/2" thick foam panals between studs...this made a flat flush floor across the room. I then used 3/4 T&G flooring on top...pad and carpet over that.
The real idea behind my plan was warmth in the long cold Michigan winters and not sound...thought I'd mention it anyway. The floor is extreamly solid regardless of the number of kids jumping around.
BTW, I did do double wall construction along with 5/8's drywall...16 foot sheets, very heavy on my old back!
