I use both bottom ported OHM Walsh speakers and rear ported Dynaudio monitors. The thin carpet and pad over concrete floor prevents a lot of bass interaction with the floor, especially with the bottom ports. When I use same speakers on the floor above with typical modern plywood flooring under similar carpet, bass can be overwhelming and harder to get under control.
I've also used front ported B&W P6 floorstanders and Magnepan planars in same rooms. Maggies were the least sensitive to flooring type sound wise for sure, but harder to get clean full extended bass out of. Much less interaction with the floor acoustics it seemed with those.
