OK, how can you physically tell if a tri-lam tweeter is blown? I ask this because I was about to pack up my RT25i's for shipping and noticed what I think is a little tear in the upper portion of the tweeter. Thing still sounds great so I'm not sure what's going on with the tweeter. Still useable? Or should I replace the little sucka? Anyway, here is a pic. The tear is in the circled part.
