I consider a peak of 95 dB at my listening position loud. I would never listen to the music that loud, but I would turn it up that loud to show the system off, and/or to test out components. I usually listen in the high 70s to mid 80s (dB). With a speaker that puts out good bass you should be able to do all the shaking you want without having to output ear damaging dB levels (or you could always go with a dedicated sub).
As far as shaking shelves and other stuff, that is just a good way to destroy your hearing...
