That's a fine tweeter. What my surrounds do is remove the additional info radiated by the speaker baffle. That reflection, diffraction it's actually called, is superimposing itself, mixing in, upon the pure info propogated by the tweeter. That is quite possibly a problem. It's removal does a lot of things. Intergrating the tweeter to the midrange is one. The way the soundscape takes on more realism and gestalt is another. Instruments are separated out better spatially, radiate more dimensionally, possess more body. I hate using words to describe these things because they are static. Try it for yourself. That's best I can tell you. It's enhanced my experience of listening to my recordings and the pleasure it gives me. That reflection is a distortion and the ear/brain don't like it for very long.
