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,
