I usually don't post here but saw your subject line on the main page
You may want to try the Telarc 1812 Overture towards the end when the cannons are fired. Be very careful if your setup with 2 ch track goes to the sub. Lots been posted on that CD. Fundamental is at 5Hz
When I got my Cd some years back, I read the insert. Real period cannons used, progressively larger, more power, and windows were blown when they recorded the cannon sounds separately from the music. Be careful.
