ACA Sentry 95

[Gil]

Does anyone have that picture of the supposed ACA Sentry 95 that was in Minnesota? If so, could they please post it?

I'm wanting to bring this topic up again. What all do we know about this prototype siren?

I think that Nelso posted a picture of what is supposedly a Sentry 95.

All I know about the Sentry 95, based on an ad, is that it has round ports.

This might sound like a dumb question, but would round ports make a different sound than square ones? By diferent I mean in pitch or something.

[SirenMadness]

Round ports would probably give less of a choppy accent to the siren than square ports, because there is less air being expelled out of the stator at the very beginning of an interval of opening of a port on the stator.

Here's what I think is what you're talking about. It's the only one like this I've ever seen.

I'm getting File too big to hotlink. :/

EDIT: Sigh, just have to open up a new tab and do it that way.
