Each horn must have a very narrow vertical and a very wide horizontal dispersion.
2.
It used a 6 driver articulated array having approximately 180?horizontal dispersion and 40?vertical dispersion.
3.
One for the maximum vertical dispersion of hits and one for the maximum horizontal dispersion of hits.
4.
Brian Cheney invented and patented a Constant Directivity Wave Guide ( CDWG ) to increase the horizontal dispersion of the planar mid-range and tweeter.
5.
They are attractive in these applications since nearly all ribbon tweeters inherently exhibit useful directional properties, with very wide horizontal dispersion ( coverage ) and very tight vertical dispersion.
6.
In service these guns chronically suffered of great horizontal dispersion, both from the worsened thermodynamic performance of the guns themselves and from the unequal quality of the shells fired.
7.
In addition, he developed curves that are now interpreted as the vertical and horizontal dispersion coefficients, " ? z " and " ? y ".
8.
There were four air-motion transformers of the mid-sized upward firing variety in a 180-degree format, instead of the traditional horizontal dispersion amt common with all of the " home " type loudspeakers ESS built.
