on a tip I snagged a high/low note set of Buell Reed horns, same type as the ones used for the Red Wings goal horn. I've figured out how they work, anyone interested in a write-up?

ok, I finally got the time to do this. This is the set I got: they're Buell Trombone marine horns. These things are pretty weathered; and judging by how they're made they look like 1940s manufacturing tech. I only pulled one apart for this, but this is what they look like inside. air goes in here: this is the rear chamber. It has a (hexagonal) hole for air to pass through, this is important: this is the reed, plate, and reed retainer pin: Plate/pin removed: The "reed" is actually a small copper disc about the size of a penny. it covers the horn inlet and has just enough room to rattle/vibrate around: from what I can see, the way these horns work is that air enters the front chamber and lifts the reed off of its seat. air then rushes past the reed out both sides; some through the horn, and some through the rear chamber causing the reed to vibrate. The pitch of the horn is determined by 1) the volume of the rear chamber, 2) the volume of the front chamber, and 3) the length of the horn. since the horns' pitches are set by those physical attributes, they should play the same notes regardless of how much air you give them. More airflow just makes them louder. Supposedly these things can take 200+ psi. but I can blow through them and they make noise, though they sound rather farty and pathetic. I gave them about 20 psi at low flow with my hobby air compressor and they sounded pretty close to the JLA horns. just not very loud.
