Issue with a speaker that trips the amplifier

Hello everyone,
Following a somewhat intense use of my amplifier (a Yamaha (115W) - I don't remember the exact model, but that's not the issue), one of my speakers (Magnat Monitor Supreme 2000 (220W)) causes my amp to shut down above a certain volume (above -10/-15dB when both are connected). There must be a safety feature preventing it from blowing, so I think the speaker demands too much power (I had never had a problem before). I imagine one of the components has burned out, but I don't know much about it, so if someone could help me it would be great!
PS: I tested just with the other speaker and I can crank up the volume all the way without any issues (except with the neighbors of course ^^), with other cables and the other output of the amp >> it works.
Thanks in advance!

For those who have the same problem: it's due to a capacitor that burned out in the speaker. I'm going to replace it and that should do the trick!

Hi
It must be the speaker that's dead, even though it still works; it’s probably the coil inside the speaker that has come loose. You can tell by pressing on the diaphragm, and if you feel any rubbing, to see the difference, try it with another speaker to make sure that's really it. Unfortunately, the only way to fix it is to replace it.
You're right when you say that the amplifier goes into protection mode when the speakers have a problem or aren't up to par. -
Hi! Thanks for your response, but how can I be sure that it comes from the coil? I don't see any difference when I press on the diaphragm and especially there are 3 drivers in the same speaker, I don't know which one has a problem... Is there another way to check? And can it be repaired without spending too much money instead of replacing the driver?

Hello,
Watts refers only to the maximum power that a speaker or a cabinet can handle.
On the other hand, efficiency is important; the higher the efficiency, the less strain the amplifier will have in driving it.
It's strange that a component of the speaker has burnt out, the efficiency is very good "93dB"!
If you don't want this to happen again, redo the filter of each speaker with quality components.
