ns10 - how to check if tweeter blown? replace?

I had my master volume accidently up and now the tweeter on one of my NS10s is not working.

Is there a test to see if it definitely is blown? I remember something about putting a 9volt battery across the terminals?

and if it is blown...would I be able to replace it myself (is it just clips?)

Thanks,
Keith

the test is to listen to it and see if it sounds blown.. probably is if you turned the volume up to far.

When I did that I snuck into my record company and swapped it for one of theirs! chalk one up to the muso's! Although a record company exec wil ever notice..

thanks for the replies gents...
I will have to order a replacement...was "listening"more to it...yep, fried!
(of course, it doesnt help when you are recording with a stuffed up nose/head, but even I could tell!)

I'll pop it open and take a look see at how to replace.

Thanks again,
K

I've had fuses installed on my NS 10 and NS 1000 tweeters. Saves me a packet.

Very good idea: Fuse passive neardields...especially NS10s.
Much easier and cheaper to replace a fuse then a tweeter.

Bad idea-Chokes or colors the sound.


And you really want a thermal fuse which i don't think i've ever seen on a pair of NS10's.


Best idea- By an amplifier with enough juice to drive it openly.


Also stay away from digital feedback.

I noticed little difference in sound when fuses were put in. The savings on tweeters have been huge particularly the NS1000's which aint cheap in this part of the world... and yeah dam it... the fuses did not save the tweeters when my Big Ben (at my instigation) put some major digital noise through my system.

FWIW about 16 years ago I had to replace 2 tweeters before decideing to fuse. Eventually, I had Bryston 7Bs with silver speaker cables. The NS-10s remained fused. No problem but then again I never loved the way ns-10s sounded. I still have one room with a pair of KRK 9000s and NS-10s for nearfields. It's not a large room and there is a crown PS-400 in that room. Primarily used for hip hop tracking. They're fused. YMMV.
I no longer use NS-10s in my mix room.

Speaking of coloring their sound. Remeber (for a minute) the craze was to place tissue over the tweeters?

I can't believe we're at Gearslutz and nobody suggested putting a meter across the tweeter.

And, yes, a fuse will absolutely make the tweeter sound different.

I agree. It seems that it's usually underpowered amps driven to distortion that blow tweeters.

That is what kills drivers. Your amp should have 2ice the power output that you speakers can eat. This way you won't hit them with distortion. And if you do blow them up, they'll lite on fire and it will be cool.

the power amp had plenty of juice, it was the extreme loudness of digital feedback that did 'er in!

NS10's can sound worse than they already do?

Have any of you guys replaced your NS-10 tweeter? Did you do it? Is there soldering involved?

Though I am not highly schooled in electrical engineering, I had this thought. If the argument is that a fuse, due to the gauge of the fuse wire being so small, is acting as a current limiting device, putting a fuse inside the cabinet only in series with the tweeter should not compromise the sound. When you consider the lower current being delivered to the tweeter vs the woofer you are only an inch from the tweeter voice coil wire which is probably smaller gauge than the fuse element.

Just look inside the speaker housing. It's a simple matter to desolder and take out the blown tweeter. Just duplicate what you see regarding old tweeter connections. Remember to duplicate + and -. It only takes a few minutes to perform the operation.

Can NS10 tweeters be repaired? Typically when any speaker blows I assume it's blown for good. What actually happens to the speaker element when a tweeter blows?

That was on the original vertical NS10s, not the ubiquitous horizontal NS10Ms. And they needed it. Sounded kind of harsh after long bouts of mixing.

If I see someone use tissue on NS10Ms, I immediately assume they do it because they read about it or saw an old picture of original NS10s, not because they determined they needed it by actually listening.

Sorry to add to this. How can I test tweeters in krk vxts. I did a room acoustic measurement and it dropps by 30db from 10khz to 20 khz although the tweeters are working.

I have exactly the same problem. Do I need to replace HF drivers on both monitors (to keep them identical) if only one doesn't work properly?
