Question about Audio Players & Recorders

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 fine it's the tweeter. Inside the cabinet there are two circular things one for tweeter one for bass. Could I just cut these both out and connect the speakers directly to the amp's speaker wires ?

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)

Have 2 jbl 615 get good base and sub but neither tweeter playing


You will need to determine if it's the amplifiers or the tweeter themselves that are not working. If you open up the cabinets and check each tweeter with an ohm meter for continuity it will show if the tweeters are working, in which case the amp is the problem. if the meter shows that the tweeters are blown, you should still hook up another tweeter or speaker to the horn amp to see if it's blown and therefor took out the tweeters.
If any of this sounds complicated, you'd be best off taking the cabinets to the repair shop.

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.

The top part of the mackie speaker isnt working. all that is working is the big bottom part, and the sound sounds like the bass is the only thing coming out.


The typical cause of this is a blown tweeter or the tweeter has broken off of the horn and fallen inside the cabinet. Remove the screws from the horn and carefully remove the assembly. Try the speaker at low volumes to see if you hear any sound at all. Next, remove one of the wires and using a 9Volt battery quickly touch the 2 leads on the tweeter. If you don't hear a click, the tweeter needs to be replaced. Contact Mackie service for a replacement.

If you hear a click, then the problem is in the crossover or amp and further investigation willbe required.

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.

Thanks and regards

I have 1 set of wharfedale speakers valdus 400 .power handling (programme) 150W .normal impedance 4-8ohms.1 of the tweeter is not working .please advise how to repair asap ,thanks


you should first try if the driver is really gone or not, maybe it's just a wiring problem, also there can be something wrong with the cross-over network. Check the tweeter with a multimeter, if you don't see something between 2-16 ohms, you need a new one (or two, you probably won't be able to find the original part, so you'll have to change both left and right channel drivers) but if you see the desired impedance on the meter, check the internal wiring, crossover solder joints, capacitors, etc. I hope this helps.

Yes, you can easily check it by removing it and swapping it with your other one. If the one from the second cabinet works, then the speaker itself has died. If not, either the wiring is the problem, or the crossover in the cabinet. If you take the first speaker that wasn't working, and put it in the second cabinet and it works, then likely it's your crossover. Please rate my answer, thanks.

Need to replace 11L tweeter


the best solution I've found is this:
1. Remove all the tweeter screws.
2. Take a thing metal rod (a coat hanger should work) and lightly tap the tweeter through the top port in the rear until it is loosened and comes out. The tweeter is totally sealed so you probably won't damage it if you need to do this to a working tweeter.

This method also works for the woofer but you need to be very careful to tap the frame or magnet of the woofer and not the cone.

The tweeters are probably blown, i had the same problem.
You can test this by placing the cable on the dismanteled crossover at the back of the speaker. colour blue/yellow.
No high volume please.
See http://www.hometheatershack.com/forums/diy-speakers/4549-wharfedale-modus-one-six-crossover-pics.html
for pictures.
If the tweeter is blown it can be dismanteld with the aid of a screwdriver, horizontally.
Place it between the tweeterbowl and the ring which has the mark wharfedale on it. The tweeter comes loose. On second hand sites you can buy little speakers, like modus one or two's with the same tweeters for a good price and put them on your larger speakers.

This how i repaired 2 of my 4 modus eights.

good luck Danny Mol
