Re: What's wrong with my speakers? (sound clip)
What amp and speakers? Sometimes, harmonically rich amps will drive a certain frequency real hard, making a speaker do that thing called "cone cry." It's where that frequency buckles the speaker. I notice it most on D or B single notes. Your clip sounds bad, tho. I'd try another cab, or check the wiring that the amp is plugged into. I've had weird sounds like that when an "almost ground loop" is happening with pedals or cables.
