Burnt voice coils mean burnt voice coils. Maybe they could not take the power they were rated for. Maybe cooling was insufficent. Maybe they shorted , or resistance dropped in the crossover causing them to eat more amperage than expected.
Indeed, the volume that (based on specs) would be needed seems deafening. Why don't I see similar complaints all over the place for other brands (with less efficiency and similar power-handling)?
Tell me exactly how you have established with certainty that this poster did in-fact abuse this speaker. Please describe the specific abuse that was done and your proof.
"Maybe" monkeys will fly out my butt.
Repeat: Standard universal industry policy is that burnt voice coil always defines user abuse and is always excluded from warranty coverage.
Please stop wasting bandwidth till this statement is disproved.
Everyone reading this is surrounded by several trillion miles of conductor called "wire." Wire has well established and well known current and voltage capacity. There is a safe range, marginal/borderline range, and range beyond which said wire burns.
An excellent example of wire with specific current rating is the tiny conductor wire comprising a fuse.
Current flows through a dynamic coil speaker driver's coil. Guess what? The coil is wire! That wire has well known and well established current rating. Earth to readers: Disagreeing with that current spec doesn't change it! If/when you find a flaw with such current ratings, please do a PhD thesis on it and let us all know! We won't hold our breath.
Current from the amp flows through the tweeter coil. Beyond a certain current, guess what happens? Think hard now. C'mon....keep thinking.....I know you can do it!
Yes, it burns up! The voice coil opens and burns up to powder/cinders/smoke, AKA "products of combustion."
Still confused? I hope not!
No, an evil witch did not curse your tweeter to an early failure with low current, sorry.
You can just as soon return a blown fuse for a free warranty replacement as claim warranty coverage for a blown/burnt voice coil.
If these current ratings for wire are not accurate, then why does not the entire world have examples everywhere of burnt wire conductors burning for unknown and unknowable reasons?
One reason I can state for this tweeter blowing: Eric overstates power handling, because the tweeter pole is low and/or slow, resulting from the two way design.
But this does not transfer blame from the user to Eric. All or most speakers overstate power handling to various degree. Klipsch overstates sensitivity 4-7 dB.
It's up to the user to listen to the speaker, the closer to the limit the more carefully, and never cause the speaker to audibly distort.
