Hi, many years ago I remember being impressed by some speakers that looked a
bit like footballs. The ones I saw were made by Toshiba as I recall, but
were out of my price range. They had literally speakers mounted in a multi
sided solid a bit like a dodecahedron, and covered up with some kind of
foam. You could hang them from the ceiling or on a stand. Very heavy for
their size. The mounting was die cast.
With a bass bin they actually sounded very nice.
You do not see this sort of thing any more,, so I'd imagine they had a
strange impedance. It was interesting as they seemed to not have any
tweeters or anything and one would have thought the reflected sound would
have mucked up the stereo, but at least in the couple of demos I attended
this was not true.

It wouldn't necessarily have a strange impedance. With 12 8ohm drivers
you could get 6ohm overall by connecting them in series-parallel.
And it would work just as well as a Bose 901.


Another strange speaker I recall from long ago was just a gimmick I think,
as it had a definite smell and a crackling kind of sound. It was a plasma
modulated with audio. Weird. Completely impractical of course.

Gimmick? Impractical? Bugger the ozone layer, I want a pair of plasma
tweeters.
