Test this : Gd bless you
Line noise is feeding in from the AC line. Use an ac line filter to block the line noise. RF (radio frequency) interference is being picked up by the power line or wiring. Remove sources of RF interference, such as fluorescent lighting or wireless devices not designed to work with audio/video equipment. Wires between the components are on top of one of the components; the transformers are causing RF interference. Be sure that wiring goes behind the components rather than on top or between components. If there is an equalizer in use, there could be a ground loop. Ground loops can be resolved by installing GLI's (ground loop isolators) on the cables connecting to the equalizer.

SOURCE: karaoke speaker,no woofer or midrange working, only tweeter

Hi, it's probably that the 8" woofer and the midrange of the "amped" enclosure is open. One way to test is to remove just one wire from the inside of the enclosure to the woofer or midrange in question and with the use of a continuity tester (or a VOM), check for the resistance of the coil of each the 2 speakers. Both should read anywhere from 4-8 ohms, if there's no reading (VOM needle will not move) then the coil(s) are open. In the absence of a tester, a single AAA or AA battery would do (pls. some would argue that this is not a sound practice, however this should be enough for you to be able to determine the condition of the coil(s)). With the use of the battery and a single short length of electrical wire, apply power from the battery to the terminals of the speaker, if the cone moves, then chances are it is good, if they don't then you would have to replace it. Am not sure if available in your area, but there are some trained people who can rewind the coil should a replacement speaker be not readily available. Hope this be of help. Please let us know how things turn up. Regards.

SOURCE: subwoofer makes loud popping crackle intermittently

im having the exact same problem thinking it was the amp i rigged up a different driver,the amp was fine.i knew the driver wasnt gone and after some looking and testing i got it down to wire mesh(i think a dust sheild,something)inside which was slightly rubbing on the coil,it worked fine loud when it was warm but cold there was bursts of bad feed back noises.

SOURCE: Bose 123 Home Theater speakers started crackle sound?

If the wires are bare on some parts and touch eachother that will most likely be the cause.

SOURCE: No sound for Velodyne ct-100 sub woofer

Sounds like a dead amp. You could check the xformer output and the amp IC's with a VOM.

These amps do not cost a lot, about $40.00. and are easy to replace.

Tweeter no sound but speaker no problem


In the most general, basic sense, I would be assuming that this is just one speaker and not 2 with this problem, or 3 or more.
Only way to get the ball rolling is pull the tweeter from the cabinet, checking to make sure all wires are connected at the tweeter and inside the speaker.
If that is the case, then you would need to determine if this is the tweeters fault, or its crossover (thing that divides the sound into whats right for the woofer and what the tweeter wants).
If you have a multi-meter, you would disconnect the wires from the tweeter, set the meter to ohms and touch a probe to each speaker terminal. No action means burned out tweeter, 100% action means burned out tweeter, a reading slightly less than the rating on the back of the tweeter (for instance an 8 ohm tweeter would show anywhere from 6 to 8 ohms on the meter) means tweeter is good.
If you have no meter then take the tweeter from the good speaker and swap in place of the bad one, making sure you respect + and - connections.Its a little risky this way,since if there is something wrong in the speaker it may hurt the good tweeter..(the meter is the safer bet). If it works, then you need a replacement tweeter, if not the problem is either wire connections inside the speaker, or something is wrong with the crossover.

Remote reset


Yes the woofer and tweeter can be replaced but the woofer needs a recone kit to repair as the whole speaker cannot be replaced without replacing half of the speaker enclosure.... call JBL pro or a service center for help.

No woofer sound from my K3000FX. Verified all cables and settings correct- but sound only comes from tweeter. What could it be?


Step 1:

Hate to say it, but possibly a blown speaker. To check this, do the following -


Step 2:

Insert headphones into jack to verify for sound there.

Step 3:

Unplug unit and open rear panel to reveal speakers.

Step 4:

Remove leads from woofer.

Step 5:

Using a multimeter, set to OHM (horseshoe) to lowest setting.

Step 6:

Apply red(+) and black(-) to speaker leads. Meter should read at least 4-8 ohms of resistance.

Step 7:

If no reading, then voice coil is blown.

Step 8:

If no meter available to use, the use a 9 volt battery by applying direct connection to speaker leads in an off-and-on fashion - You should hear a "click" sound come from speaker. If no "click," then speaker is blown.

Step 9:

If click is heard, and resistance on meter is correct, then the amp circuitry leading to the woofer may be blown = repair needed.

WHEN YOU PUSH DOWN EVENLY ON THE SPEAKER ITSELF...IT JUST SUDDENLY GIVES-WAY, WITH A KIND OF POP. DOES THIS MEAN THAT THE WOOFER IS BLOWN??? AND IF SO IS IT POSSIBLE TO REPAIR THIS TYPE OF PROBLEM? ...


The first thing to do is to check the resistance of the voice coil. Get an ohm meter & place one lead on each of the speaker terminals. If a value of 0 ohms results, or no reading at all, the voice coil is blown.

If you are pressing in, and suddenly gives way, my guess would be that the excursion of the speaker was too grand (common with car stereo, everyone loves bass) and the wires that wrap around the voice coil of the speaker were broken from the speaker inputs.

It is possible to recone the speaker, but by the time you track down a recone kit (highly unlikely that it is even available) you would be rather deep into the project.

Long story short:
check the speaker terminals with an ohm meter. If you get a resistance, they should work with free woofer movement. No resistance = blown woofer.

I have a Cerwin Vega E-315 speaker and the Woofer has stopped working. The Tweeter and Mid-Range still work just fine. I just do not get any sound from the Woofer.


Pull speaker so you can get to the terminals in back. Take an ohm meter and check the ohms of speake, a 4ohm speaker could measure up to 5ohms and still be good. If the reading is way off then it is blown. If speaker is good, then check the cross over thats in the speaker, some models put fuses on the units for protection, but mostley on the high frequency of the cross over, not the low.

The voice coil is open, you can look real close at the spider wires that are soldered from the two terminals to the cone to see if they are bad, otherwise you will need new woofer, you can try getting the woofer from partsexpress.com

Tweeter not working


Check the continuity of the removed tweeter with a VOM meter (I use an original Heatkit MM-1 available on eBay for $20) and do the 1.5 volt battery click & scratch test mentioned above.

Celestion A3 tweeters (also used in the A1 and A2 speakers) or the replacement diaphragms are no longer available from Celestion. A1 speakers show up regularly on the United Kingdom eBay website for $300 or less and are small enough to economically ship to the USA. You would also end up with a midrange spare speaker (assuming it is the same as in the A3 cabinets)

The part number for the A series 3 bar tweeter is T4969/P. The 3 bars refers to the 3 bars in the casting to protect the dome. I got this number from the box of my spare tweeter I have the earlier 1 bar castings in my A3's.

Go to www.ersatzteil-versand.at do an "artikelsuche" (article search) for the number T4969/P and something extremeley similar shows up except that they list the manufacturer as Onkyo. The part number and description are so similar to what is printed on my spare tweeter box it would be worth 81 euros to see what shows up.
I have designed an adapter plate for either a Scan-Speak Revelator Tweeter D2904/710002 4 ohm, 1" soft dome, 70 mm diameter magnet, $220 or a Vifa D27TG35-06 6 ohms, 72 mm diameter magnet, 91 db, $37.50..Both are available from:
http://www.speakercity.com/ in Burbank, CA


39baa5b.jpg
I only modeled the front flange of the tweeter to save time. I have not built any of these yet but the price would probably be $400 for a pair of adapter plates and speaker flange modifications. But when you are done you would have replaceable tweeter for a long time to come. The 2 protective bars are drawer handles available for $3 each.

Other possibilities are:
http://www.audioloudspeakers.co.uk/boultons.shtml voice coil rewinding in the uk

http://www.speaker-repairs.com.au/coils.htm voice coil rewinding in australia

http://www.speakerex.com/diaphragms_new.html in Florida can rebuild the woofer and replace the midrange but no longer have the 4 ohm diaphragm for the tweeter.

If you want the drawings (and 3D geometry file necessary for the machinist to make the curved edges) for the adapter plate and tweeter flange modification contact me at mercedes280se-4@yahoo.com

Woofer doesn't work


sounds like the voice coil could be open or damaged. the woofer can be reconed. reconing replaces all the moving parts in the speaker frame returning to new condition in most cases.

I have a set of cerwin vega ls-12 3way woofer works but tweeters


There is an old cheap way to test any speaker. If you have a multi-meter, set it on OHMS. Then, while holding one lead against one speaker terminal, tap the other meter lead to the other speaker terminal. If the speaker is good, you will hear faint crackles. If you do not have a meter do not despair, you can do the same test using an AA or AAA battery with leads held to the battery.
Good luck! P.S. Nice speakers.

My Kenwood amplifier is having problems, whenever i turn it on. all seems well until i play some music through it, after 30seconds to a minute the music will cut off and a distinct click is sometimes...


Your amp is going into protection. The click you hear is a relay meant to protect your speakers and stereo. Check your speakers with an ohm meter for the the proper ohms ( listed on the speaker ) and physically try to push each woofer and midrange cone in gently to make sure it moves and is not stuck or frozen in place. A speaker may read correctly on an ohm meter if the woofer is ok but if the tweeter or midrange is not working it will cause the amp to go into protection mode. When you play music stick your ear up to each tweeter\midrange\woofer to ensure they are working.
Your stereo could also be the culprit although usually if it plays music it is ok as long as you are not hearing loud pops. Loud pops are voltage spikes that indicate that a transistor\IC is breaking down and will eventually short. Good luck!
