does the turbokat have external loudspeakers? I'm guessing
no, but I don't remember if they ever used any in the series
or not. besides, jets are pretty loud. (but I'm going to
give them noise-cancellation technology, so there.)
The SWAT Kats have used loudspeakers in at least one episode that I know
of: "Chaos In Crystal," when Razor tells Shard that they're trying to help
in (and Shard, of course, refuses to listen). Offhand, I don't remember if
they used speakers elsewhere in the show.
Exactly *where* the loudspeakers are is a good question; *that* I don't know.
