If you have it, Peter Gabriel's "So" contains a great test track that I've used to identify a clipping-damaged tweeter (been there, done that, more than once). Check out Track 8, "We Do What We're Told". No need to listen to all of it...the opening measures before the lyrics will tell you what you need to know. If there is damage to a tweeter, you will hear a scatchy obviously distorted sound. You'll know it when you hear it. If it sounds lyrical and smooth...so far, so good.
