Today I pulled apart an 035Ti I purchased to repair a broken input lead. When I inspected the inside of the dome I found the foam from the pole piece or phase plug was stuck to the dome and coil. I'm not sure what to call the center of the magnet structure in this case. I cleaned this all up, removed the remaining loose foam and finished the repair.
This gave me an idea about the tweeter this was replacing. It had low output. I pulled it apart and the foam was the cause of the low output. I cleaned and reassembled it and it was again in good woking condition with normal output.
This left me with questions
Do repair kits come with new foam discs?
Should the foam be removed completely?
I have only removed the offending foam and left what was attached as I assume it is for damping?
