I also have the 1812 overture and when the cannons fire, my current speakers make the house vibrate, the maggies never did that. I have a Cranberries CD with organ music in it and the low notes will shake the floor and can be felt in my chest, not so with the maggies. I go to a lot of live shows and the bass can be felt as well as heard, that can't be said about music being reproduced by maggies. I am not picking on Maggies, over all they are the 3rd best pair of speakers I have owned, I just think that they lack bass and are power hungry.
