that's an ugly rolloff graph, but can you consider bass from a pa in a concert hall far field..? i mean, i dont care where you are in a room when the mule plays, the bass is going to thump your chest. and that is the case in alot of these concerts. obviously there is no substitute for a field test, but i think that graph might be deceiving, esp. since "far" and "near"are a bit ambiguous, esp. given the purposes for which we would be using the mics...
i just hope they are as good as the omnis are - i should think they would be the way to go for the larger concert venues, when placement is not ideal...
