Proac Ribbon Tweeters Damaged

Hi all - this is my first submission, so looking forward to your responses...

I own 2.5 year old Proac D48 R speakers, powered by a Parasound Halo A21 amp (about 8 years old). When listening the other day I thought the speakers sounded dull, muddy. It appears both of my ribbon tweeters have gone out and I am at a loss to understand why.  The amp is certainly not under powered to cause clipping damage and I never play my unit abnormally loud  - maybe 1/4 to 1/3 total volume.

As you can imagine, my repair/driver replacement will not be covered by warranty as this is not considered a manufacturer defect. I am told the tweeters run $399 per.

Worst thing I can do is have these repaired and then have it happen again. HELP!

I was only talking about shipping the tweeters to Millersound, not the whole speaker. Your lucky your dealer has the expertise to fix the tweeters.

By the way, I had four 7" scanspeak woofers, the two in each speaker, just stop working all at the same time.  Fortunately, the speakers were under warranty.  But before they would replace them the dealer wanted me to send in the nonworking speakers to figure out what had happened.  They could not.

Thanks. He will actually have to replace the tweeters.

My speakers are under warranty but my dealer stated as both tweeters were blown at once, it was caused by a "system problem" and not manufacturer's defect.

But my amp seems to be functioning normally, so????

Like I said, I'm at a loss to understand how this occurred and want to prevent it in the future, post repair...

Ribbon tweeters are delicate. That Parasound puts out 400 watts into the 4 ohm Proacs. If you have a DC leak with that amp it will damage those tweeters. BTW, my friend owns that speaker and it is one of the best speakers that I have heard!

Um, you should check to see if the ribbons are truly what is damaged. Lots can go wrong in the crossover.

Best,
