I started tinkering with speakers (mostly amplifier circuits) and I learned a lot about how sound and amplifying works but I don't understand how to increase quality
I have several kind of speakers , 0.5W , 1W , 5W but some speaker's quality better than others , I don't understand why ?
Their rated power is same , resistance same , size is same but sound quality different why ? (Both of them almost never used before and no visible damage )
I know my question seems like off topic but I want to know what's determining quality (factors or reasons)
Like quality depending on amplifier or speaker (maybe both ?) And what makes two same sized & power speaker better than each other ?
Edit : I want to make myself clear , When I say "quality" I don't mean noise or spikes . I mean audio sounds better (like it's more similar to real life voice)
For example : My cousin bought sennheisher headphones (I'm not advertising brand ) and when they stop working he gave them to me and I noticed internal speakers are almost same as mine but somehow mine sounds worse , why ?
Also I'm sorry if my question so hard to read because of grammar errors
