Monitor speaker buzz

[maorgr]

Hi,

I have a single B2031 monitor speaker which sounds great except when I pick the 6th or 5th strings, there's a buzz coming out of the speaker along with the note.. (connected to the AXE FX 3)
Is there something wrong with the speaker ? I tried connecting a headphone and the AXE3 sounds perfect

Please advise if possible.

Thank you in advance.

put a foam mat under the monitor or something similar
