Davy Posted March 23 Share Posted March 23 Hi everyone, I have an Ashdown 1x15 neo cab that I'm using with an Ashdown ABM 500 head. It has a buzz at a certain frequency when played at gig volume. I'm guessing it's not the speaker as I can stop the buzzing by pressing on the grille with my foot. I've checked all of the screws holding the grille in place and they are all nice and tight. Other than removing the grille, I'm not sure what next step might be. Has anyone had this issue before and how did they manage to fix it? Cheers Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted March 23 Share Posted March 23 It could be the tweeter, I had a similar problem with an Ashdown cab and it was part of the tweeter that was vibrating/buzzing (even though I always switched it off). They changed it for me. Happened on the lower frequencies. Quote Link to comment Share on other sites More sharing options...
alexjbassist Posted March 23 Share Posted March 23 The grill on my ABM 4x10 rattled... I used rubber washers on the screws that hold it on which stopped the problem 👍 1 Quote Link to comment Share on other sites More sharing options...
stevie Posted March 23 Share Posted March 23 Grilles can rattle for a variety of reasons. Ideally, you need to pinpoint the exact location of the vibration. The most likely source of the problem is around the edge of the grille where it's attached to the supporting batten. The screws could be vibrating against the grille, in which case @alexjbassist's solution would work. It's also possible that the foam strip beneath the grille has disintegrated or isn't damping the grille effectively. You would then need to replace the foam strip. 2mm thick should do the job. 1 Quote Link to comment Share on other sites More sharing options...
