A) Everything I post is deleted after 24hrs. It literally says that in my profile. Try reading before making yourself look stupid.

B) There's nothing factually incorrect about that quote. It doesn't even disagree with your number rattling rant. All speakers contain the exact same parts. There's no mystery to them. You talk about response like that actually means anything, but that speaker is still vibrating away at frequencies it's not designed for, you just can't hear it. That doesn't mean the speaker doesn't "work", it means to make a good speaker by audio quality standards it needs to be made in a way that actually produces the desired sound. A bad book is still a book.

C) The only thing about about downvotes is the rate limiting. Otherwise I don't give a shit. The ability for an in group to act like chimps doesn't actually make you correct.
