So i've been putting my new Eden XST through its paces since the weekend, and I noticed something new today. I always keep my Tone knob on my Thunderbass all the way down, but i turned it up, and with the tweeter control at 12 o'clock i kept on hearing buzzing, almost like the sound coming from the tweeter was static-y, i turn the Tone knob down again, and its gone and it sounds good. Are highs the first to go with weak batts or something? is my tweeter gone? with my tone knob down and my slapping away, the highs sound fine. I'll swap the batt tomorrow when i get another one, but if anyone has anymore ideas i'm open to suggestions and no. the speakers never lit up either EDIT: and for the record, the treble EQ on the IOD did affect the amount of buzzing in terms of loudness.
