In the first few hours of use this might be ok - voicecoil adhesives are getting "baked"
But later in life - you are burning up the ferrofluid and possibly damaged the kapton paper over the coil wires and may have caused arcing (that strong smell)
The op speakers probably failed a short time after the original post unless it was "baking"
