4x10 speaker buzzing, help?

[caden000]

This may have been discussed before, so apologies, search function's a mess.

Ive got an acoustic B410 (no complaints, i love it) that im using with a hartke 3500A. the cab is 8 ohms and so the amp is only pushing 240 watts, and the cab handles 400. but recently ive been getting a slight unwanted buzz from the top right speaker. i took off the grill and all the screws are tight, so its not rattling against the frame. i dont know whats wrong or how to fix it.

its my only cab, so if it means removing that particular speaker and going with a 3x10, i guess that would be ok, but please include how i would go about wiring that.

thanks

did you take the speaker out and see if a wire was touching the speaker from the back side....that can cause a buzz and is easily fixed....and no i would not remove one speaker and just use 3 . depending on how they are wired together it may cause the other speakers not to work at all or cause some crazy type of ohm load depending on the rateing of each speaker!!

1. You can cause mechanical damage to a speaker with FAR less power than the speaker's rating. Using too much bass boost is one of several possible causes.

2. You must run all the speakers in that cab. To do otherwise (either by pulling one speaker or by simply disconnecting it) would give you a drastically mistuned cab that will sound like crap and may put the other drivers at risk when you try to compensate with EQ changes.

I agree with the wire touching the speaker suggestion. Also check to see the speakers are well snugged-up to the baffle board. Sometimes the screws loosen up. Don't sock 'em down hard at the risk of stripping something, just snug 'em up.

Be very careful of that in your case. Those B410s are made of particle board, I striped one of the screw holes in the one I had. Fixed it with a tooth pick.
