guys..i know it's an old thread, maybe someone can shed some lights to the issue i am having..my old audioengine A5 right speaker (the passive speaker) got very low or soft sound to it..i manage to change some caps but the volume is still low abt 30% - 50%..potentiometer seems good that no issue in increasing or decreasing the volume..but cant confirm if that is the real problem..anyone having the same issue and managed to solve it?
