Speaker buzzing?

hey! I have just built my internet radio and everything seems to work and I was so happy to have this thing
until I realized that with a bit bass the speaker starts buzzing and it isn’t fun anymore to listen to that music. So I can hear cheezy music or classical and nothing with bass.

I am wondering that there isn’t any topic about this. If it isn’t so common, then do you have an idea, why I am having this problem??

thx

I’d have a double check of all of your connections on the speaker, especially where it make contact in the board with the terminal heads. It’s possible that there’s a faulty connection somewhere that’s dropping out some of the lower frequency range.
Make sure to check the solder on the back of the speaker as well, as that’s a possability!
