I would not want to use a horn with vertical pattern too large. For one thing, nulls appear above and below the forward axis and it is best if the nulls are set outside the horn's vertical pattern. And for another, radiation at large vertical angles really only serves to increase ceiling and floor reflections, which is an undesirable property. For this reason, all of my horn loudspeakers are designed to use a 90°x40° horn.
