Thanks for the information, alwsjr. Whenever the foam plays out I will probably spring for the signatures myself. Anything worth doing is worth over doing is what I say.

I should have written this post before now because I need to update matters on the AER MD-3. When I really closely examined the driver with the problem I found that the brass phase plug had unscrewed from it's complete attachment position to the point that I had bent it over, probably while dusting the horns for ten years. and it interrupted the free movement of the voice coil. After I straightened the threaded brass rod which attaches the phase plug I screwed the plug correctly in. When I listened the subject MD-3 in an Oris 150 horn it sang as sweetly and musically as always.

As I mentioned earlier I have a substantial vision impairment. I only see from one eye and it has had two surgeries this year.

The reason I should have written this sooner is to remove the insult I paid to the MD-3. They really are great drivers.
