weird "woofing" sound?

[PolishSasquatch]

not sure where to post this, but basically: when i play some chugging style stuff, mainly open palm muted 0's my speakers in my 4x12 seem to woof out. or at least one does. but it donest exactly woof out, as the sound is much more shrill. kind of like a paper crunching sound..but loud. I can only notice it without earplugs but then my ears fell like theyre gunna bleed. It may be my grille (its metal) thast shaking, but not sure. i doubt i tthough sounds like its coming from the speaker

PS: cab is a behringer BG412H

Does the sound like crunch out and then fade back in slowly?

If so, I had a similar issue, it was a rectifier tube going bad... or do you mean your actual speaker itself tops out?

Same problem... its a bad speaker.

bad speaker? ****... i think its the top right one, but i cant get my ear close enough to the otehr ones without it feeling lie its belleiding and major feedback

take the grille off and gently tap the speaker cone with your finger.. it should sound a little like a drum.. 3 of them will sound the same, and one of them will sound dull, vibrate weird, or make a funny noise. Thats the bad speaker.

Musicians friend sells the replacement speakers for like $70... its a pretty easy job

Just some friendly advice, if you're going to spend $70 for a replacement speaker, head over to avatarspeakers.com and get a nice speaker.

I've noticed this a few times but it only happens when I am playing my 7 string tuned down to G and jamming the palm mutes... I don't think my speakers are bad because thats the only time it will do it.
