Yes, that is what those babies cost. Sometimes you see one for maybe a grand or so, but still awfully spendy to blow out.

dead diamond tweeter
Quote:
I’m an engineer so I’ll weigh in with three technical* ideas: 1. Publicly shame B&W into providing a design change so this never happens again. 2. Sell the speakers and buy something that is properly designed. 3. Start a class action lawsuit- put ads in Stereophile and TAS. *Adding a bandaid to a bad design never produces a desirable result.

I owned a pair of 800 D2 for seven years and run them on Accuphase power amps (P-800, after two years replaced by A-200). In June 2014 I broke one tweeter mechanically (by stumbling and falling against it). The pretty thin diamond diaphragm was shattered into pieces. My dealer charged me Swiss Francs 667 (which I think was what he had to pay for) and came to replace it personally. That's what I call customer service! The above mentioned incident was the only one with a tweeter. However in 2016 and 2018 I had to replace a total of three bass units (LF02372; USD retail 486.53; my dealer charged me Swiss Francs 350 each) because of partly broken diaphragm suspensions (beads). I do not know whether I damaged them by occasionally dusting them off not sufficently carefully or whether it was an environmental / thermal / aging problem. Hope you will find the cause of your problem soon. Martin Last edited by meltemi; 10-28-2020 at 08:53 AM. |

Tweeters (including their housing) are matched to the corresponding models. The tweeter for 800 D2 Series (ZZ14388; USD retail 1086) is different from the one for 800 D3 Series (ZZ28738; USD retail 1205.46). Martin |

Interesting info, Meltemi. Have visited your great CH many times. Sounds like I need to get to know your dealer!

BW Diamond Tweeter Design
Quote:
Versions before the D3 had a removable tweeter grill that was held on magnetically and was easy to pull off. The diaphragm material is very fragile and thinner than a human hair and is easily shattered by any physical contact. I have driven the speakers hard on many occasions with solid electronics (Classe Delta amps) minimizing risk of clipping, which will destroy any tweeter. I feel it is unfair to bash B&W for having an inferior design on their diamond tweeter. On the D3 the diamond dome is one of the only components they did not change because it works and sounds excellent in my opinion and many others. My two cents.

Like I said earlier I have not had one diamond tweeter issue on my D2 or D3 for over 10 years and I have absolutely cranked my system on many occasions. This is not a design issue or quality issue for B&W diamond tweeters. If you know absolutely no physical contact has been made I would suggest you look elsewhere in your system for the cause of failure. Last edited by Greg Gale; 10-31-2020 at 02:23 PM. |

Glad you have had a good experience.
The large number of failures of these tweeters is not a coincidence.
