Don't waste your time.
Like all cables, it has a sound. You have to drink the Kool-Aid.
Thermal Distortion your loudspeaker most likely suffers from it. But do you care?
Thermal Distortion is much more serious than just a maximum power handling limitation or side effect.TD is overlooked by most manufacturers as there is no easy (low cost) solution and TD is audible and measurable most of the time at most power levels. TD is caused by the conductive metal (aluminum, copper, or silver) voice coil getting hotter when you pass electrical energy through it. The more power you pass through it the hotter the metal gets. The hotter the metal gets the more the electrical resistance increase. The efficiency goes down and you need to ram in more and more power for smaller and smaller increases in SPL. It can be the reason you get fatigued while listening. If you are running massive power you are creating more TD in your transducers. But do you care? And is it a reason some prefer horn-loaded designs or SET-powered systems since they have the least problems with TD?

ditusa, Thank you for the interesting paper you attached to one of your postings. I just got around to reading it and it is very interesting. Not only does heat affect the voice coil, to the extent the heat gets into the magnetic structure, flux is affected which further adds to thermal compression. I also did not consider that changes in Thiele-Small parameters also add to compression. Finally, I might add that although the paper does not mention this, heating of the components in the crossover will add to compression. |
