did you get the aluminum tweets or silk?
i dont like the aluminum diamond tweets, way too harsh, but the silks sound just right to me. the aluminums work well in cars like S2000's (convertibles) but for the average person, they are too much.
did you attenuate the tweeter any? on the crossover there is jumper for adjusting the tweeter, it should be -2, 0, +2. 0 is the default, so you would want it on on -2, try that and see how you like it.
