Why do they use aluminum voice coil? From what little I have read so far, Aluminum only recommended in speakers due only when you have high power source. If not its still recommended to use Copper.
Basically what I read it doesn't make sense to use aluminum voice coils in headphones, and probably why Sennheiser seems to be the only one to do so, and rest of industry either use copper bobbin or copper clad aluminum voice coil. Did notice that the K701 and K702 use flat wire aluminum, another headphone that doesn't truly shine until driven by an amp well above its own value.
My impression so far is copper used to conteract the limitations of aluminum which conducts too much heat and burning the speakers. Instead of using some sort of polymer, copper is used instead.
Seems AKG and Bose turned to using flat wire or flat ribbon aluminum to address the same issue above and to avoid dialectric breakdowns.
So I can find good reasons why AKG and Bose use flat wire aluminum and other uses copper cladded aluminum voice coil, but can't find any good reason why Sennheiser uses the voice coils they do. Its also the reason why I suspect they have a veiled sound unless powered by expensive amps/tubes and why their signature sound that many find unimpressive is pervasive in their entire line of audiophile/personal headphones.
Love to read some input and discussion about this. The pros cons of aluminum, copper and aluminum flat wire or ribbon. I'm sure I am correct on everything, but would shed some light into why some headphones are so hard to drive and why they maintain a veiled sound until used with powerful amps. And for those of us who are not as knowledgeable on this subject.
Also more interesting to read than another suggest me a headphone because I can't use the "search" button. That was in jest right there if you happen to miss it.
