I know that there are STH- and STL- 10's, but what is the difference between the two?

STH10s were the high tone version of the two sirens (
Single
Tone
High
10 horsepower). The STH10 had 12 stator ports and 12 horns.

Single

Low
10 horsepower). The STL10 had 7 stator ports and 7 horns.

Thanks. But what does the 10 in the name have to do with anything? Or is it just there?
EDIT: Oh, stupid me. I should have read more thoroughly.

Actually, STH-10 stands for SPECIAL tone high, STL-10 is SPECIAL tone low, not "Single Tone"
.

Ha! I still learn new things once in a while!
I've always heard both words used interchangeably though.
Since I got the STH/STL10 wrong, what does the SD10 stand for? I've always heard that stood for Special Dual 10 horsepower.

SD-10= SPECIAL DOUBLE-TONE 10HP.
Don't worry.... everyone makes that mistake

Funny.
I was about to ask that.
My Chinese wife call them "Garbage can on pole."
I recorded an SD-10.
Was very loud near the bottom of the pole from which I made the recording. I wanted to hear the pole-mounted controller operate.
Seems that too much sound goes down which would be.tter projected out.
