What's wrong with my speaker?
If you are thinking of saving a bit of money by trying to repair it instead of replacing the driver you are mistaken. 
Jamo concert 11 sound issue.
probably the drivers. Crossovers unlikely. Could even be the cabinets. 
Is the ideal multi-way a 3-way with limited bass?
Wait wait, last week we were all schooled that all speakers sound exactly the same. Now we are being educated in how different speakers sound different depending on how they are built?When will the madness end?? The differences that are report...

Relatively small speaker with a "big" performance: Role Audio Starship SE model
My review has some of the measurements you are seeking.

change amps or speakers
he has a 60 watt amp with too low input sensitivity 
Poor Fritz
It's knarly because of the title... Which is how the OP intended it... He likes to troll then call foul when it goes in a direction he doesn't like. who is the troll?
