well the way not to create problems is have a giant electrostatic panel.
starting from that point we create problems in an attempt to make the speaker smaller and more practical.
certainly i am creating problems by curving the ribbon and loading it into a waveguide - but it is not without a reason. it allows for a smaller ribbon. if cost was no object i wouldn't do it. i would simply run a ribbon from 1 foot above floor level to about 8 feet above floor level. i hope you agree that a ribbon that is maybe 6 inches long is potentially cheaper than one that is 7 feet long.
i definitely believe that line source will always outperform a point source ( and a plane source will outperform a line source ) but point source is just CHEAPER.
my idea of a curved ribbon is intended as a COMPROMISE between a point and a line source which allows for a certain degree of optimization via differeing degrees of curvature as well as different shapes of waveguide.Rerurn to Romy the Cat's Site
