Believe it or not, that is my "small" horn! What I've got in the back of my ST now humbles even the cruise ships. This beast came from the dismantled hulk of the former Great Lakes ore carrier "Joseph H. Frantz". It rumbles the ground at 66 Hz. Unfortunately, there is no way to capture the experience of this horn in a video or audio clip--how it sounds is not much without how it _feels_. It's a visceral experience standing in front of it when it blows, and we haven't even given it full power yet
