I don't believe it! I've had the rev D 12" sincs april and now its speakers have gone very odd... It's obvious they need repair, every 40 seconds they let out a loud distortion noise which sounds awfull! distortion is the only way i can discribe it. It is def the speakers themselves becuase on mute the sound is non existant. Has anyone experiened or even heard of such a problem? Not sure what to do, i couldnt bare to send the thing away. Will i have too? Please help! edit... okay now it's stopped. It did it yesterday at about the same time, and stopped as well. Is it the other side trying to contact me? or am i missing something obvious here? it has been hooked up to external speakers, would this effect the internal speakers when i used them straight after?
