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.

Are u sure u haven't messed up with the polarity of the speakers while rewiring the speakers? If all is ok and only u find that the speakers are not so vibrant as the other there cud be a possibility that the coil has shifted inside the magnet and is either scratching or not aligned. Also hav a look at the crossover

Hi Katrina,
Yes parts are available for your R909 speakers.
firstly I am surprised that you have managed to blow both tweeters and crossovers.....there must of been some serious distortion/amplifier clipping involved there???
So a couple of things.
Can you actually see damage to the crossover boards? If so what components have been damaged? i.e board loactions and parts.
The crossover is available but they are not cheap. $1560 each (AUS)
So it would be preferable and much cheaper to repair them at board level.
Tweeters are also available.. $745.00 each (AUS)

How to hook up Panasonic SB PM19 speakers to SA-PM23 reciever


yes you can. these are called "bi wired" speakers which means there's a hook up for the woofer and the tweeter individually. If your amp have just 2 speaker hookups it's no problem to hook the woofer/tweeter wires of each speaker together. If your amp had 4 speaker hookups, you could put the tweeters in 1 and the woofers in the other but it will still work fine with 2 speaker hookups.

Tip

How To Bi-Amp And Bi-Wire Speakers!


What is the difference between bi-wiring and bi-amping?
Bi-wiring is using the same power source (amplifier) but separately connecting that power source to a woofer and a midrange/tweeter on a speaker.

Bi-amping is using two separate power sources (amplifiers) and connecting one amplifier to a woofer and the other amplifier to a midrange/tweeter on a speaker.

How do I bi-wire?
Your speaker must have two separate positive and negative connections (one set for the woofer and one set for the midrange/tweeter). Connect one wire between the positive terminal on the amplifier/receiver the positive terminal on the speaker. Connect the other wire from the negative terminal on the amplifier/receiver to the corresponding negative terminal on the speaker. Remove the jumper straps connecting the two sets of speaker inputs. Repeat this process for the second set of terminals on the speaker, connecting them to the same positive and negative terminals on the receiver/amplifier. Repeat the steps for each speaker you wish to Bi-Wire, connecting them to the appropriate terminals on your receiver/amplifier.

How do I bi-amp?
Bi-amping is similar to bi-wiring, but involves separate amplifiers: one for the woofer and one for the midrange/tweeter. Passive bi-amping involves a direct hookup between each amplifier and the speaker terminals. True bi-amping involves hooking the preamp to an electronic crossover that replaces the passive crossover network in the speaker. The active crossover then connects to multiple power amplifiers.

No sound from tweeter bx5a


First of all, never connect the audio from your receiver directly to the tweeter. You can blow the tweeter instantly. The mid-bass driver can be damaged from a direct connection as well.

Since you get absolutely no sound from either driver, this seems to implicate the crossover. If the crossover has opened, no signal gets through, if it has opened early in the signal path.

But, it is also possible that a short exists, and that perhaps your amp cuts off the output having sensed a short. The short could be in the crossover or one of the drivers.

Here are some troubleshooting tips--

To prevent damage to your amp, turn it off while making or breaking any connections inside the speaker boxes.

Write down which wires get connected to which place on the drivers, so you can get them back where they belong.

With your amp turned off, connect the bad speaker to your amp. You've already verified that no sound is produced when both drivers are connected.

So, with your amp off, disconnect one wire from the tweeter in the bad box.

Briefly turn your amp on and listen for sound.

If you get sound, the tweeter is shorted.

If you get no sound, with the amp off, reconnect the tweeter in the bad box and disconnect one wire from the mid-bass driver.

Briefly turn the amp on and listen before turning the amp off.

If you get sound now, but not before, the mid-bass driver is shorted.

If you got no sound either way, check the DC resistance of the mid-bass driver (only, not the tweeter. Ohmmeters put out a small DC voltage to test resistance. That DC voltage might damage a tweeter, maybe. Don't risk it). Ohm the mid-bass driver while it is not connected to the crossover. If the driver is good, you should read some ohms--a little less than the stated impedance. An 8 ohm driver might read 6.5 ohms, for instance. If you get an open or a short (with the crossover disconnected from the mid-bass driver) you have a blown driver. Two actually, since neither the tweeter nor the mid-bass driver produced any sound in the previous tests.

If you can't get ahold of an ohmmeter, try this--

Open the good, working speaker and place the two side by side.

Connect your amp to the bad speaker box only.

With your amp turned off, disconnect the wires from the mid-bass driver in the bad box and connect them to the mid-bass driver in the good box. Disconnect one of the wires from the "good" mid-bass driver first, so you don't have two crossovers connected to it at the same time--even if only one of them will get powered on. It keeps the confusion down to a minimum when trying to isolate your problem. Oh, and disconnect one wire from the bad tweeter, in case it is shorted.

Turn the amp on and listen briefly before turning the amp off.

If you got sound, the "bad" crossover is fine, but the "bad" mid-bass driver is blown. And, since you got no sound in the previous tests, the "bad" tweeter is blown, as well.

If you got no sound, try it the other way around. Meaning--

With the amp off, disconnect the speaker wires coming from your amp from the bad speaker box and connect them to the good speaker box.

Your amp is now connected only to the good speaker box.

With the amp still off, connect the mid-bass wires from the good box to the mid-bass driver in the bad box. Remember to disconnect one of the "bad" crossover wires from its own driver first, so only one crossover is connected to the "bad" mid-midbass driver. Remember to disconnect one wire from the "good" and "bad" tweeters, so the only sound you hear--if any--is from the "bad" mid-bass driver, powered by the "good" crossover.

If this produces sound, but the previous attempts failed, you have a crossover problem.

If you still get no sound, something went wrong and you need to retest the good speaker by itself and back up a few steps and try again.

Assuming you got sound from the "good" crossover while it was driving your "bad" mid-bass, make sure no wires have come loose inside the "bad" box. Assuming you have sound connections at each end of each wire, you now need to desolder the electrolytic capacitors from the circuit board.

Make sure you mark them first, so you can put them back where they belong.

You can remove only one at a time, if that helps.

Use an ohmmeter to check some components.

The big red coil should read pretty close to a short, maybe one ohm.

The capacitors should read open or infinite resistance, although you might see a steadily increasing resistance while the capacitor charges up from the ohmmeter. If you read a steady low resistance on a capacitor after it has been removed from the circuit board, that capacitor is bad and must be replaced. The markings on the capacitor should give you some clues as to the proper replacement.

All things considered, I suspect that your problem is a shorted electrolytic capacitor. But, I gave you all I could think of so you can narrow it down and isolate the problem, whatever it might be.

I hope this helps.

Can't get wharfedale melton 2 tweeter to work. Looked inside cabinet and need advice on internal wiring please. These are very old but one works perfectly and the 12'' bass driver on the problem speaker is...


The tweeter has burned out and cannot be salvaged. I also own a pair of (ex) Melton 2s. In the beginning Wharfedale were good at supplying spares (see www.wharfedale.co.uk for contact info and advice). A few years ago after my cat destroyed the 12 inch unit in one, i invested in new insides, including state of the art 12 inch woofers, 4 inch mid range and 1inch tweeters with a good 3 way crossover. The cabinet is great so consider asking a techie friend to do this for you. Please don't just cut out and connect to amp speaker wires! You will get terrible sound and risk ruining both amp and speakers! Best regards Karl (karl@simpson.nom.fr)

All the electronic parts you can see inside the speaker (usually capacitors, coils and resistors) are responsible for breaking the full audio band (bass - middle - treble) in parts (2 for your case) and feed each part to the appropriate speaker. By that I mean that you must not use your speaker without the cross-over (this is the name of the circuit) since this can harm your speakers. The sound from a speaker without crossover will be terrible for your ears too. Eventhually you can try to connect your tweeterat the amplifier's output leads, assuming that the volume level will be very low. Using this connection you can just check if the tweeter is working ok or not, so you can find where is the problem. By the way I don't think that a coil is burned out, try to see some resistor possible burned out.

In case of a problem or clarification, don't hesitate to post.

My mordaunt-short avant 908i front left speaker aluminum tweeter stopped working... no sound coming out, however two midrange speakers functioning just fine.


I had similar problems my tweeter was blowen and it had to be replaced... I actually blew the speaker many times using a NAD amp as there were spikes coming from the amp. I changed the amp to a Marantz PM7200 and have had no problems since.
