Why do my Opera Secondas sound soooo bright?????


I just bought a used pair of Opera Secondas (first generation). The previous owner has had it for a year and a half at most and I don't know how much he used them. When I set them up in by listening room, I was unpleasantly surprised about the tweeters. I have had NUMEROUS "bright" speakers in the last 20 or so years (b&w cdm 1nt, thiel 1.5, mission 753, linn keilidh, psb silver, totem 1's, and I'm sure i'm missing a few) but I have never heard anything like these Operas!!! I'm pretty sure these have been broken in and if that's the case, then what's up with these highly rated Secondas???? HELP!!!

Gemini, from your description it looks like
a) your amp doesn't drive the spkrs (I checked the Seconda tech specs they are not the easiest to drive)
b) there is something wrong with the mid-bass units. You would have noticed that, so this is an unlikely option
c) there is something seriously wrong upstream -- also unlikely as the sound is OK with the Triangle.

The Seconda is a close design which makes it a tad less easy to drive.. can you borrow a bigger amp to try on them?
lol, down boy, down!
Anyways, whats your equipment that you are using to drive these speakers?
Agree with Gregm and Marakanetz. It would be a good idea to try and use another much more powerful amp to try and go from there.
