Hi, I was wondering if anyone knew anything about these shells.  I'm not

really sure what they're called, but they're usually used when
converting an auditorium into a concert hall.  They are placed behind
the orchestra and basically look like an added wall of panels with an
angled upper section.

All I can find out is that the upper section should be parallel to the
angle of the ceiling and that if shells are placed on the sides of the
orchestra, they should not be parallel.  This prevents an echo.

I would like to find out how tall they should be, what they should be
made of, how long the upper section should extend from the panels, and
how to angle the top if the ceiling is not at an angle.  In general, I
want to know anything and everything about these shells.  Anything would

helpful.
