No sound coming from tweeter

[Forty six and two]

All the sound including guitars and vocals is coming from the mid range driver. No sound from tweeter. What could be the reason. Help. Thanks.

Could be a fried tweeter, intermittent wire going to the voice coil, crossover issue even a loose wire inside would do it. What where you doing when the fault occurred?

thanks for replying. Honestly i never noticed. I dont even know for how long no sound is coming from the tweeters. By listening speakers sound just normal. Mid range is playing all the sounds. But one day i casually put my ear near the tweeter, thats when i noticed tweeters are just silent.

IC. Sounds normal enough actually. Do you have a multimeter with Ohms? If you do then unscrew the tweeter and pull it off the box, disconnect the wires and check the tweeter with the multimeter and meter the resistance of the tweeter. If it is zero Ohms or open then there is a issue with the tweeter.

When listening to normal music at normal levels, the tweeter will be very much quieter than the midrange (even with your ear next to it), but you should still hear small sounds especially percussion.

Even my bad ears can tell if a tweeter isn't working. Play percussive music with cymbals, then try covering the tweeters gently with the palm of your hand (don't touch them though) and then quickly take your hand away - repeat - you should hear clearly if they're working or not.

In my day, tweeter damage was most often a clipping amp taking them out, but I don't know the speakers or amp to even begin to confirm from a distance I'm afraid.

What speaker are we talking about? What's it used for?

I just replaced the tweeter voice coils in my small PA speakers (FBT Jolly8 ba). I expected them to be fried, possibly due to long feedback, but they looked like new and the DC resistance was infinite. The service technician was just as puzzled as me but had seen it before; could be caused by a very high amplitude peak. This however should have been prevented by the internal limiter.

You means vocals also will be coming out of the mid range? But i usually listen at considerably loud levels -20db

I have apple music. Can you recommend any song that i should play to test the tweeters

Anything with a good 'assertive' drummer

I'm going back to my earlier music years just now and recently been playing plenty of Brand X, best known for having Phil Collins as enthusiastic drummer... The title track from 'Masques' is a good one, as it's not too loud/busy but with plenty of percussion (by Morris Pert r.i.p.) - also available on Youtube too

Audacity can generate tones. Try generating a tone at 5-10kHz.

Be careful and keep the volume down. The tweeter can't take as much power as the woofer & midrange and the LAST thing you want to do is fry it by testing it! And don't go to 20kHz where you may not be able to hear it, or where your ears are less sensitive. You can also fry speakers with sounds you can't hear!

no sound is coming from the tweeters

It would be unusual for both tweeters to blow at the same time.

You have a point about both tweeters. So tweeters are not supposed to play the vocals? I always thought majority of the sound like vocals and guitars are played through the tweeters.

I think it could be the issue in the amp because all the music is getting played from the mid range driver. Is there any setting i can change in the receiver?

Have you frequency swept the speakers? Both tweeters going at the same time is more common than many people think. Sweep the speakers at a medium volume and not too too loud and see what they are doing.

So tweeters are not supposed to play the vocals?

The "main vocals" are below 1kHz (in the mid-range). But there are higher harmonics that help with intelligibility and the tweeter handles the "crispy" part of the "T" & S" sounds.

On occasions when I've had just the tweeters connected it's surprising how little sound there is.

 

[Mnyb]

There is usualy no fundamental notes in the tweeter just overtones and harmonics .

Music is mostly midbass and midrange

Try cymbal crashes or electronic music .

So tweeters are not supposed to play the vocals?

Tweeters usually start obviously playing when there is hissy stuff (like the "S" sound of a voice) or musical sounds with a frequency about the same as the top few keys on an 88 key piano, or the highest notes on a violin.

If your hearing is "normal", and you don't hear them at all, they could be blown.

Or your ears could be blown.

If the speaker is a two-way passive and has two sets of binding posts, disconnect the speaker wire from the woofer so only the tweeter plays.

Or disconnect the speaker cable and touch the terminals with a 1.5 volt battery. That chould make a distinct "click".

 

[Mnyb]

It’s has quite high xover 3500Hz I think data is not very clear .

 

[melomane13]

crossover is at 3500Hz.

I think if you don't hear frequencies above this threshold, you would be deaf enough to know it. Do the speakers have a double terminal block? it is possible that the contact is not made towards the treble. or as already said by others, the tweeter is broken.
