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!

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

Best,

Thanks all. The primary source is a Parasound Halo CD-1 player. Also occasional vinyl via Rega P3. But all has gone well for 2 1/2 years using these...
If it really is the tweets, did you recently replace your speaker cables?? Sometimes high capacitance can lead to amp oscillation.
If it were me, I'd have the amplifier checked for DC leakage before having the speakers reconnected with the new tweeters.
