Tweeter material and their effect on fatigue.

[Mouse]

I'm suspicious aluminum tweeters are giving me hearing fatigue. I look it up online and see this is a thing. Some people say metal tweeters cause hearing fatigue (with exceptions) and textile tweeters are easier for longer periods.

So I never make another mistake like buying aluminum speakers, please share your experience with tweeter and woofer materials and their effect on sound and your fatigue if you experience it.
