Just noticed that one of the 6" drivers on one of my Eyris 3 is no longer, erm... driving. It's moving a bit, but I think it's primarily due to the pressure exerted by the other driver in the speaker. It's main job is to handle the lows.. and it's not quite reaching there. When swapping channel inputs, the tone is definitely deeper my other cabinet. My guess is it's just a wiring issue, due to the fact it's not distorted and has no visible damage. So my question, am I stupid to attempt to open this cabinet.. and see for myself, or am I better served to take it to someone who knows what they're doing? Opinions, please!
