Model 5 High tone

[pyramid head]

My siren at CV-TEC, the sound pressure came out to be 128.2 point-blank. I did a small presentation on sirens and sound before we started, but that would be too long to even bother putting up. I hope you all enjoy it as much as I did.

Is that a 10-port model?

No, it is a 12. She only runs at 3200 RPM, which will only make 640 Hz, explaining the slightly lower frequency.

Great job on the restoration! You've been working on this for a long time. It sounds like the older "heavy rotor" version, which in my book, is the more desirable kind of Model 5.
