I aways wonder why speakers are sounding so different, they all have metal baskets, magnets, paper cones and copper voice coils and they all look almost the same.

Is there anybody on this forum, who can explain me, why one speaker sounds good and an other (same looking) sounds bad.

The same problem do we have with diaphragms, they all look the same, but they sound different.

Why some people love a particular speaker/diaphragm, and other people don't like them at all.

I think here on this forum are people with a lot of knowledge, who can exactly tell me why same looking products are sounding different.
