Yamaha NS-10 Tweeters both broken: what´s the reason? How to

Fede · Post by **Fede** » Sat Mar 30, 2002 6:26 am

Hello everyone

After two years of good listening my Yamaha NS-10 decided not to work anymore: at distance of a week one tweeter after the other has burn out. This happened without any overdrive or larsen or anything else, by simply using them at low levels. The damage appeared gradually and not istantly, they shut down slowly. I'd repair the tweeters if I knew what caused them to break, because one of this tweeter actually costs about 150 euros; changing them will cost 300 euros: and if there's something wrong in my system they can break again. Anyone knows what is the possible reason?
The amplifier used to drive them is a common integrated Cambridge Audio A500 (50W+50W)
Any suggestion is greatly appreciated

Thanks in advance
StratF

Best way to fix it is to move on to new & nicer sounding monitors

Maybe ones that are internally biamped...

yeah but if you love 'em............(that's why yamaha keeps making those darn tweeters)

Hey sub, right, that would be the best solution, but my problem is also about money and this takes to spend more, however it will be probably the choice, but for now I don't know, cause I loved them very much.
...maybe I win some money with the lottery and I get new speakers and the old ones repaired...just dreams
My choice will depend mostly on understanding the manner to treat NS-10s without causing other damages in the future

Thanx

you know,if there is no spike or other audio overload and it's NOT simple mechanical failure,then it COULD be a problem with the power amp.(outputting dc or some other exotic disease..unlikely) not too many things could cause this.......(ultra high or low freq clipping out of the range of human hearing could,maybe...and yes,low freq clipping WILL bypass the xover.got too much sub bass?)

Hey, I don't know anything about this thing of bypassing the xover, how does it happen?

This happened without any overdrive or larsen or anything else

I mean: anything evident I noticed

I've a pair myself. They're OK but I've heard that blown tweeters are a VERY common problem. So common that it's almost a manufacturing problem....

true,a very common problem.

Well, when I telephoned to the assistance, I only said I had a problem with those speakers: the technician answered immediately at 98% the tweeters were blown, cause it happens continously and normally he has a safe set of those tweeters to be ready when clients ask...and NO any kind of warranty, nor for one day!
