The rating on the EV spec sheet IS the real power rating. This isn't a car stereo speaker that's sold through Crutchfield with Sony-type power ratings that are nowhere near reality, they're from a well-established company that makes a lot of equipment for commercial/industrial/musical applications and the specs they offer are used by engineers when designing systems for long-term use without problems.
When a speaker blows, several types of failure can occur and if anyone blows a lot of speakers, I guarantee that the signal being sent to them isn't what they're designed for, or the drivers aren't in the correct cabinet WRT power handling.
