Tornado Warning & Sirens: Jasper, Indiana 4/19/11 (Federal Signal DSA)

[Cars2fan]

Either then the siren going high then low. If you listen VERY CLOSELY in the back ground you can hear i think to be another Federal SIgnal but i think its a model 2 or 5.

DSA's and Modulators are the same thing, but DSA's are just speaker thingys and Mods and cooler looking. They have the same speakers/drivers.

@weatherstorms The title says it's a DSA....

[weatherstorms]

@hi91023 I know. I'm just saying the sound sounds directly like the modulator, that's all I'm saying.
