Have a listen to this Sentry!!

It sounds like it doesn't like a certain something or someone, as if it's holding a grudge.

sounds like the dual tone version of this type?

[Archon]

that one is 10/15 ports

Sentry Siren's website says that most/any of their single toned sirens can be offered in a 970 or so Hz frequency "when extreme distance is a must."

[500AT]

I asked Sentry if they could have the 10V2T, 15V2T, or the 20V2T sirens custom manufactured with dual 920 Hz rotors, and they replied "yes." Any of their dual tone sirens can come with two 460 Hz, or 920 Hz rotors, as single tone models.

I would love to hear a 20V1T with dual 920 Hz rotors.

[sirenman1bd]

its almost as high as the ATI's 1000Hz tone, except this is infinite times better

Ditto!
ATIs = ME NO LIKE!

Either that thing has sixteen ports, or it is on steroids.

Yup, sure is a sixteen port. What a great noise it is, isnt it?
