Es porque han pasado exactamente 30 años, así que no creo que sea tan extraño. Hola a todos, han pasado algunos días desde mi última publicación, pero tengo noticias que compartir. Finalmente decidí hacer dos cosas. Quizás recuerden que sospechaba que el problema era el ferrofluido de los tweeters. Una de ellas fue desmontar los tweeters para verificar que el ferrofluido estuviera completamente seco. Los limpié siguiendo los tutoriales. La bobina móvil y las cúpulas parecían estar en perfectas condiciones. Compré el ferrofluido en eBay. Todavía no ha llegado. El segundo que hice fue desmontar el crossover y descubrí que había sido completamente reconstruido y modificado con condensadores de alta fidelidad. Es muy posible que este trabajo se haya realizado en Argentina. Les mostraré fotos de lo que encontré. En general, suenan fantásticos, pero los tweeters están un poco apagados y sin brillo. Si no es el problema del ferrofluido, entonces debería revisar el crossover.

Hi everyone, it's been a few days since my last post, but I have some news to share. I finally decided to do two things. You might remember that I suspected the tweeters' ferrofluid was the problem. One of those things was to disassemble the tweeters to verify that the ferrofluid was indeed completely dry. I cleaned them as the tutorials indicate. The voice coil and domes appeared to be in perfect condition. I bought the ferrofluid on eBay. It hasn't arrived yet. The second thing I did was remove the crossover and find that it had been completely rebuilt and modified with some audiophile-grade capacitors. It's very possible this work was done in Argentina. I'll show you photos of what I found. Overall, they sound fantastic, but the tweeters are a bit recessed and dull. If it's not the ferrofluid problem, then I should check the crossover.

Hello friends of the NHT club, I've finally been able to examine the speaker's crossover and draw some conclusions. It's clear the speaker has been internally modified, perhaps leaving only the original cabinets and drivers. The crossover was adapted for bi-amplification. Mundorf caps and some internal Van den Hul wiring, along with a WBT binding post, were added. Finally, four additional screws were added to the midrange driver. I don't know when or who did it, but they sound great. It's a bit of a Frankenstein build, but oh well! I've attached some photos. Greetings to all.

Oh a fantastic journey. Here I can't get qnother NHT speaker. Saludos

Thanks

Thanks Bob Thanks 3M

Thanks for your comments. However, although I don't know the full history of my 2.5s, it seems highly unlikely that anyone in Argentina would have undertaken such a complex upgrade. Because it involves modifying the crossover as well. I think it was more likely a hybrid pair, released just days before the 2.5i, which already came with a double binding post, came out. It must be said that both tweeters sound identical. But they have traces of dried ferrofluid, as can be seen in the photos. That said, they still sound very good.

Thanks I've owned a pair of NHT 2.5 speakers with silk dome tweeters for a month now. They were manufactured in June 1996. The binding post for WBT Germany is quite striking. I'm sure you all know much more about the brand than I do. I'm all ears.

Thanks 3M
