CD volume imbalance
Posted by floydandrews on May 21, 2023 at 10:48:47:
I have been using Altec 908-8a compression drivers with GPA aluminum diaphragms for years. Recently, one of the drivers is just slightly lower in volume than the other. I thought that I was losing hearing in my right ear, but when I turned around, the problem turned out to be a slight imbalance between the drivers. What might have caused this? Is there anything I can check that might be affecting the response? Dust or something in the gap? Do ferrite magnets lose charge over time? I suppose I could use an L-pad of fixed resistors to balance them, but I would prefer to correct the problem if I can.
