I did think about a possible oscillation problem but I have tested the amp carefully on both 8ohm and 4ohm dummy loads with both sine and square waves at different frequencies and could not detect any oscillation. I will test again directly connected to the speakers instead of a non-inductive load.
Well I still have no clue why it happened and if it will again someday but for now they are fine.
Sorry I can't help you but actually none of the speakers had any kind of reference written on them. They are definitely all built by davis acoustics.

Thanks anyway. I have MBL311E monitors which by the look and specs are based on Davis 17cm midwoofer used in Cesar and I'm beginning to think of adding a woofer on the bottom to supplement those monitors since they are decent enough.
A friend has the same problem, except that he also burned the tweeter outside the midrange.
The only good thing about them are the acoustic enclosures, I don't like the way the drivers look or sound, they have an anemic bass, for this money there are other better options.

In the end, he changed the mids and bass with something professional from Fane Sovereign PRO 12 and 8, he is going to put a compression driver from B&C and made another crossover. I measured the bass and mid from Davis, the bass seems to me to be something low cost from the tin, which has FS at 40hz.
The measurements are made on both pairs, mid 8 inch kevlar and bass 12 inch.

Interesting because MBL 311E based on Davis 6" midwoofer is doing pretty well in all regards.. All French speakers sound thin and fairly aggressive.
Well a generalization of a trend like " all Americans are fat " Focals , Cabasse and my own Rehdekos ( I'm a big fan of French Hi-fi ) spund that way to me and electronics ( yba , audiomeca , audio mattiere ) follows. Light footed on the bright side
Understood. Just some of them, then. I was wondering if I'd missed something, since the response trend / balance I'm used to seeing from French manufacturers like Supravox, PHY, Oscellier, Triangle, Revival etc. is generally the opposite.
I had a good laugh when I discovered the spikes put in the coil,
now without metal, the 4mh measurement shows correctly, with the metal in them it was somewhere around 7.5mh as far as I remember. For 4000 euros they couldn't find a 1 euro ferrite cylinder..... anyway, I finished the crossover with Fane sovereign and P-audio compression drivers.

That's nothin compared to Audiomeca engineering blitz haha . Although Audio Matiere and Jadis is not far behind.
Be interesting to see impedance curve of original crossover.
Thinking it would have horrible dips.
Then realized the 8" woofer ...cough cough " midrange"
was just on a low pass originally?
Does it have a mid chamber for it in the enclosure? or do both share the whole enclosure.
Either way if the bass is described as anemic and your boosting with normal EQ to get anything
the midrange is getting blasted with excursion regardless.
Making a wild guess the tweeter had just a cap for high pass.
Surprised that didnt blow more often too. Being part of the wild guess it was crossed too low
to make up for a woofer as a mid with mostly cone breakup being called midrange.
Must sound horrible off axis. Or guessing that " 1 watt" that blew it was more like 10 dB of EQ boost
not including all the bass boost along with it.
