Edward,
The only repair data I have is from the thread above:
My two HD3Ps are currently being modified repaired at Moca Audio (www.moca-audio.com) in Tours, France by an acoustical engineer (Marc-Olivier Chauveau) who specializes in Audax drivers.
I suggest contacting Mssr. Chauveau and asking if he still does the service to the HD3Ps. I have a singe un used HD3P left in stock. It has deflated even never having been used.
