In light of what happened to misterdoggy's tweeter on his 802D (which I also plan on getting soon), I am a bit concerned about the fragility of the diamond tweeter. Is there any widespread issues with the diamond tweeters? I was hoping that this next speaker upgrade for me would last for a loooong time. Replacing tweeters at $1000 a pop is not what I am looking for in a long term speaker...
D Tweeters fragile??

Jimm777,
Don't you think he would have know that he had a tweeter blown???? He can't just discover it if he listened to anything on his speakers, I assume he would have noticed a sound difference..Right? . Unless he did not listen to his speakers after the Lexicon amp blew up???????? So therefore, He noticed the problem ONLY after his amp got fixed and was able to use his Hi Fi system???? Forensic HiFi stuff is intreaging here!!!!!!!- Bottom

Well It would only be noticeable in a certain range. That is to say not all the time but only where the tweeter works.
It wasn't the Amp that blew, but the power supply in the Processor. I could understand easier if it was the amp.
I think it happened at the same time, but am not 100%.- Bottom

My thinking is... if this picture shows the speaker with a broken tweeter and it was taken before the problem misterdoggy had with his Lexicon processor, then it would support a warranty claim with B&W that the tweeter was defective and shattered under normal use.- Bottom

HI All,
In defense of doggy, sometimes it is not easy to casually determine if all the drivers are working. Sometimes I will actually put my ear to the individual drivers to make sure.
The tweeter crossover frequency is 4kHz. This is a pretty high frequency. Not many instruments can produce fundamental notes that high and higher. Mostly, the tweeter is adding the high frequency harmonics. This can be tricky to detect. Usually it takes some time during a listening session to realize that something may be wrong. Often the first indication is image wander. Then its time for the old "ear up to the speaker" test which will confirm the problem or lack thereof.

I take a lot of fotos. One is of the System Feb 3, 2006 (before incident) after adding the Lexicon where you can see the tweeter intact, and the other taken after adding the Preamp Pass labs X1, is after the incident. So No question what so ever.
Plus the noise when it happened. Like a Rock hitting your windshield.
Everything sounds OK. What should I be listening for ?

I have had the 802Ds for over six months, driving them with Bryston 600 watt monoblocks at fairly high volumes for extended times. Have had no problems. At this point I don't have any concern with the diamond tweeters being too fragil. As long as I keep fingers off the tweeters I don't anticipate a problem.Those who know it all know less than those who don't- Bottom

Originally posted by bigburnerTommy, I'm very well thank you. I post occasionally but I spend more time these days listening to and researching music. My current project is Willie Dixon. What a prodigious song writer. I've also changed my system around to be more DVD oriented. Although it's in the same room, I've moved my speakers 90 degrees and the SQ has improved hugely. I enjoy my system a lot more now.

Are you using a line conditioner. Could the hum be from your current ?- Bottom

misterdoggy, I don't have a line conditioner, and from the research I have done I do not believe that line conditioners make any difference to the sound of a hi-fi system (although I expect many members of this forum would disagree).
I think that the cause of my hum is a ground loop, which occurs when two or more devices are connected to a common ground through different paths. Easy to say but hard to isolate...- Bottom

One thing for sure I believe in Current regulators because they have a job to do that we can understand. As for line conditioners, maybe they don't make a difference in some areas and make a big difference in other area depending on the current available.- Bottom

Funny that you all mention line conditioners. I not long ago made a huge investment into balanced power. The company I bought the equipment from is called Equi=Tech. They provide equipment to professional recording studios and the like. I did some reading and the science behind balanced power is sound (forgive the pun.) The way the system works is to break up 120V in into two 60V rails. The hot and neutral in the standard setup is now both hot. Each rail has a 60V supply that are 180 degrees out of phase with each other. What this does is to eliminate any noise that can filter into the equipment via the neutral. I have their rack mount unit the 2Q which also has EMI/RFI filtering. I also have a 1.5BQ which is a wall mount unit that is hardwired into the power circuit to feed my Bryston 6B-ST power amp. I haven't had the chance to run the entire system off of the balanced power conditioners yet.- Bottom
