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!

Excuse the question ... did you use a test disc? Many ribbon tweeters burn with test discs.

Nope - no test discs. I never did identify the cause, but have since replaced my Parasound amp with PS Audio Stellar  M700 monos.

i have changed ribbons on d48R three times. Always the problem due to impulses , RCA connection touched by hand etc... i change the ribbons easily. i have tried replace gs2e by gs2i, interesting but the sensitivity pf gs2i is higher so the balance of treble is not the same than the original.

I finally gave up on the Proacs. Really liked the sound, but there is something about the durability of their ribbons. After multiple failures (with different amps), I sold my D48R's and went with Spendors.  No problems in almost two years...

Wow gnoworyta, what a experience you had with such incredible speakers... I've just bought a pair of D48R!!! hopefully I won´t have to go through the same experience, never had ribbon tweeters before. We'll see. I´ve got a bit worried, but it is the first time I´ve read in forums about this potential inconvenient. Thanks for your feedback.
