[rec.audio.high-end] Spica TC-50 tweeter

Recently one of my Spica TC-50 tweeters started resonating pretty nastily,
and sounded suspiciously like a blown tweeter due to amplifier overload.
I maintain that I haven't overdriven my amp (a NAD 3150); and listen primarily
to music with relativeley low dynamic range.  I have a couple of questions
with regard to this problem:

    1.  Are Spicas *that* fragile?  I realize I'm not going to get thundering
        bass out of them, and so I don't try with equilization, etc.  But I
        feel like they should be able to play light jazz and chamber music
        at reasonable levels.

    2.  The store where I bought them 3 months ago said that they must return
        the driver to Spica for an evaluation before they pay warrany costs.
        In general, is it pretty cut and dried to tell if a driver is blown
        via amplifier overload rather than a defect?  In this case, the driver
        definitely didn't melt down; it just showed up as a nasty resonance
        with solo piano.  The determination by Spica has not yet been made.

    3.  Given that I must replace the tweeter on my own, I would like to 
        replace the driver direct from the manufacturer of the driver rather
        than pay the $40 that the store wants.  Given that Spica doesn't 
        modify the driver, does anyone know what tweeter is used in the TC-50s
        and where I can get replacements?

Thanks for any info,
