I have never used these speakers but I assure you the ones I had where fused and if you went over there rms they would blow the fuse and it had to be replaced to work again. I thought this was asomething they still did just used a resistor or something instead of a fuse. I guess they just filter out frequencies now right. But I know they do take more power then say a active set so unless you go crazy it's gonna be hard to over power a good set anyways. I would assume they would destort and sound like poop if they where in danger.
