I'm no expert but I'll give a shot at it. I think the name implies the difference. Long throw horns have narrow dispersion and are made to throw a wave and be used at a distance. Short throw horns have wider dispersion and integrate close up but don't carry as far. Ralph

That's it, more or less, but in reality the idea of short versus long throw is somewhat specious, as there is no difference in how far a 60 degree horn will 'throw' versus a 90 degree horn if they have the same on axis SPL. What does differ is the width of the coverage zone; by and large one wants a wider beam for a shorter throw so that the audience in close and off-axis can hear it. But this whole concept has been rendered somewhat moot in the pro ranks by line-array technology, which addresses the long-throw aspect via nearfield (-3dB per distance doubling from the source)coverage zones up to 300 feet or so deep, and close-in dispersion with curved (J-Line)arrays.
