Ceiling suspension was a really big thing for a while. You don't
see it too often any more except in broadcast facilities, in part
because it's hard to get good solid low frequency coupling with
suspension. But I still see it around.

Isn't the whole purpose of hanging by wires to isolate and prevent
coupling?

Right. Unfortunately now you have speakers physically vibrating in
the air because they aren't held down with a large mass, even though
they don't effectively conduct vibration into the structure any more.
You want the speaker cabinets steady because you want no radiation of
sound from the cabinet, only from the drivers.

I think the real reason that people do this, though, is because radio
studios tend to be very crowded and it allows you to put the speakers
in reasonably optimal positions (ie. with the tweeter at ear level)
without using up any floor or desk space.

So the coupling you were talking about above is coupling the driver to
air, not coupling reflections off a boundary. Action-and-reaction work
freely in a suspended speaker.

Can I assume that a mounted speaker fixed firmly in place (ignoring
reflections off the stand) would theoretically have cleaner bass than a
suspended speaker at the same location?
