Memories of a klipsch folded corner horn

I grew up listening to a mono tube Amp my father built along with a klipsch folded corner horn with a 12" 16 ohm Stromberg Carlson woofer with a 72 Oz magnet. I can still remember watching the throw of the woofer while telarc's half speed mastered recording was playing of the 1812 overture with a 5hz cut for the cannons firing. No sound. Chest compressed from the volume of air coming from the woofer. Great memories
