Thermal Distortion your loudspeaker most likely suffers from it. But do you care?

@johnk actually I am going to walk back may earlier post.

If the crossover or other electronics in a planer speaker are not suffering compression, then it is entirely reasonable for you to have mentioned it.

so it’s a sage post,
 

apologies sir.

Crossover components most certainly can get hot enough for thermal compression to be an issue.  A friend of mine who repairs gear showed me a couple of inductors he took out of a pair of speakers that where played at a really high volume level.  Remarkably, the drivers were not blown, but the plastic formers for the inductors completely melted--what was left was a spool of wire sitting in a pool of plastic.

Can anyone confirm my lay understanding that Zobel Networks do, in fact, have a significant, if not great, effect on the SQ when applied correctly to a speaker?

It's a filter. Whether the correct one may be speculative.

Please pardon my ignorance, but I am confused by the references to liquid metal wires or liquid metal passive preamps.  What metal that is liquid at room temperature is used to make this equipment?  How is it contained so that it can't leak out?
