Question about the tone of the b drum on acoustic drum sets?

I noticed that at rock concerts, the b drum always has a super loud, solid, b-y thump. I realize that it sounds so good because of the acoustics of the room, the professional drum set, and the microphone for the b drum. Whenever I hear b drums without mics, they sound rattly, loose, and un-sharp. Is it impossible to achieve an actual b-y sound with an acoustic bass drum without it miced up?
