I understand that one BA driver cannot cover the full audible frequency spectrum, so you need more BA drivers for that. Shouldn't 2 be enough though? Or 3 at most? Ok, maybe 4 MAX. lol But why squeeze even more drivers in there? I heard that doing so makes each driver do less work and so allows it to produce a lower distortion, clearer, more detailed and more accurate sound, but how exactly does it work? I just don't get it. Also, isn't it extremely hard to produce an IEM with so many drivers - like say 4+ - to make them work adequately in unison? I also heard that more drivers actually have the potential to sound more coherent than less drivers and that I don't understand at all. What's the deal with that?
I want your thoughts on this guys.
