I was listening to some music at -10 yesterday and was hearing a strange sound, i shrugged and ignored it. Then a song i liked came on and it went up to -5. A definate 'farp' 'farp' 'farp' was being overlayed onto the sound. I turned the volume down and noticed that the 'farp' was only coming from one speaker. My front left AE aegis evo 3. So i take the cover off and see that the midrange is moving around a lot more than the bass. Hmm, maybe its just the music i thought. So i check out the front right, its not suffering from the same problem, they are set at the same volume as each other. I dont have a sub yet so the bass is being directed out of these and the aegis evo centre as well. But i cant think how this could happen, i could understand a faulty driver not moving enough, but too much? It has never been above -5, and has always been slowly increased over the space of 30 mins or so. hmm, any ideas?
