F1 *12 speaker
I have had the F1 812 for 3 months the sound is unbeatable for vocals ,backing tracks and guitar.
Sadly the speaker has developed what i think is a continious rattle sound but if hold my hand against the centre grill it stops the rattle. (photo Attached) I don't think it is the speaker more like the grill vibrating.
Has anyone else had this problem?
any suggestions of how to stop it?
