I take this to mean the media extends to "faraway", so you are
actually looking through more "stuff" from the distance. You could
try limiting the media to a smaller container or use a density which
is higher in the cone of the spotlight. It's cheating of course, but
then what you ask for might be an unrealistic effect ;)

You could also try using less dense media with a brighter light
source but stronger fading (smaller fade_distance).
