As I was reading up on thermal and mechanical compression(due to a comment by Jim below), I came upon an article by someone who said that most speakers don't produce bloom and that bloom is something that you have in real life:"When a saxophone is playing at relatively low level, the sound seems to be coming from the instrument, but as the sound level increases, so does the apparent size of the sound image. It not only appears to get wider and taller, but to expand toward you. I hear this effect when I am sitting close to the stage, but on only a very few loudspeakers, and with very good recordings."
Hmmm.....
