Meadowlark Blue Heron - gas tweeter leak problem?

DDrave44

Try  the large screw in a small hole trick.  Basically you remove the original screws then put a single wide threaded screw that is just a bit too large for the original hole.  VERY CAREFULLY hand thread it into the tweeters plastic flange ( where the hole is ) and once it is tight ( not screwed into the baffle but tight in the plastic) you use a claw hammer's claw end to slowly pry up on the head of the screw.  Put a cloth under the hammer head to prevent damage to the baffle. 

I have done this on several BHs and even a few BH  centers.  Slow and steady pressure will release the tweeter from the keldamp gasket material.  Just be super careful not to puncture the outer mylar membrane.

Good luck with your BHs.

Mike,

Do you know, per chance, how to fix a deflated HD3P? 

Thanks a lot!

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. 

I came across this old thread and even though it's been 5 years since the last post, I just wanted to mention that I still have my Meadowlark Blue Herons, and that my repaired Audax HD3P gold egg tweeters (by Marco in France) inflation has been lasting about 15 months between re-inflations before the crinkling in the gold foil of the tweeter begins to show. If interested, check out my previous post above for Marco's info in France.
