Duntech repairs?

HELP!  My Crown Princes sound amazing until they hit a strong bass note and they splat, or bottom out.  We just had the surrounds professionally replaced.  I spoke with Bill at Millersound (great guy) and he said there was probably damage done in the voice coil area or something and they wouldn't touch them without the original reconing kit.  Anyone know where I might find recone kits for these?

Did you try Duntech?

@roxy54 yes. They're very slow to respond if they respond at all.  I got a facebook message back from them saying they'll reply asap, that was like 4 days ago. I have read that they can't do anything and they'll send you around the world on a rabbit chase.

This is all quite unfortunate.  As I recall, Duntech has not had an importer in the US since around the time John Dunlavy opened DAL.  And since DAL has been closed so long that can be a problem for those owners as well.  Also, as far as I know Duntech and DAL used different drivers in sibling models so that can further complicate repairs.

I can only add that I was friends with violin and heard his Princess speakers after Legall repaired them.  Bill took two steps and the result was worth it.  First my friend already had his woofer surrounds replaced, but Bill found the replacement was not the same as in the original Dynaudio drivers.  So that may have provided the wrong support or stiffness.  He had the proper surrounds to duplicate the originals.  Second, when reassembling he balanced the cones.  Anyone with general knowledge about racing engines will understand what that can mean.  Then the cones could move out and in with even, smooth motion.  True it wasn't an A/B comparison but the resulting bass was impressive.

Anyone having problems with either brand, I would add my encouragement to consult with Legall.

@pryso I have consulted with Bill Legall and he's outstanding to work with, there's a reason he's very busy at work!  He saw some pictures and diagnosed the problem pretty immediately.  Apparently this is a no brainer for an competent speaker refoamer or repairer but that's not me so he's a little over my head.  

I'm going to take them to a local shop in DFW and see if I think they know what they're talking about.  Bill suggested I do that first even though I told him I'd love to give him my money.
