Hughp3, you are correct. But many modern drivers can have a lot more excursion than the head of many kick drums, depending on how that drum is tuned. I have dual 15" woofers in my speakers, which helps a lot. If I really crank the system, it will play at levels I can only tolerate with earplugs- you can feel your organs vibrating in your chest, pants cuffs moving, etc.
If I had a real drum set in the same room, I would experience the same thing. Without a sound pressure meter its hard to say if I am really at the same volumes but for me its moot- I don't play the system that loud :)
