What does a bad tweeter sound like?

I just found the 5A crossover. :) I would leave it alone unless you are already pretty well versed.

The 5A uses batter biased caps int he mid and tweeter sections. Pretty funky if you ask me. :)

If you have a capacitor short in the tweeter path, you may get a lot more mid/bass (a dangerous thing!)

Usually, it's no sound, rattling, rasping, or tizzing.

If you have one speaker that sounds a lot brighter, it is probably the other speaker's tweeter died. :)

Best,
