Loudspeaker Quality topic

As there is no similar topic specially for Loudspeaker I decided to create one.

I like the speakers of the phone sound good and bassy.

Although I had to replace the speakers (repair),
(cuz it got low by it self (hardware defect))

But I noticed the bottom speaker is thinner and more high frequency specialized in the other side the top speaker for low frequency (bass)

Idk if it is hardware fault or it is designed by Sony,

I want to know your thoughts abt the loudspeakers 👍
