is the Protection good enough to avoid to blow a speaker?

I've been using 8040a since it was released in the first year, quite happy with the sound quality.
however, I accidentally experienced an overload in volume during mixing a music. the guitar track peaked at the highest volume and the red light was completely on for few seconds in both of my speakers.
and now I wonder if the protection circuit is good enough to avoid blowing the speaker, because I feel it sounds weird in the high and lacks clarity. :(

Hello,

The protection circuits should activate fast enough to protect the speaker/drivers from any kind of signals.

If the speaker has failed, it usually means that the tweeter unit is completely gone, meaning no output above ~3 kHz. Can you test with sine generator? Or engage the tweeter mute dip on the speaker and see if the sound changes at all?

Hi,

I just tested the speakers with a sine generator in logic, it has no problem above 3 kHz, I can still hear it.
however, I feel like it sounds a bit boxy and lacks the clarity, any further ways to test it to be sure it's no problem?
thanks!

If you can take a frequency response measurement in an anechoic room, it would tell you if the speaker has any frequency response related problems. Where are you located at? Best way would be to send it to professional service, they can check if the speaker is ok or not.
