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 tweeters are not working


The crossover caps may have failed, or the tweeters themselves burned out. Using a small 1.5 volt cell touched across the tweeter leads should produce a sound. If not- they are burned out.

I have wharfdale atlantic 400se. The tweeter is no longer working. How do i work out if it is a cross over or the tweeter


If there was a traumatic high-volume event that preceded this problem, I'd guess the tweeter died.

If you can access the connections on the tweeter and you have an ohmmeter, you could disconnect the tweeter and measure across the the terminals. A shorted or open voice coil = dead tweeter. A measurement near the stated impedance is probably ok.

If you have NO ohmmeter, you could carefully connect the output of one amplifier channel directly to the tweeter and just scooch the volume upward slightly from silence while playing something with very little bass in it. If you hear it, the tweeter is alive.

How do i tell if my problem if the high freq diaphram or the cross over


The crossovers in professional speakers don't fail that easily. It could be a blown tweeter. To confirm remove the metal grille-- remove the screws of the Horn Tweeter -- remove the cable connectors on the tweeter terminals ( Red and Black wire ). Now if you have a multimeter put it in Ohms range and touch the probes on the tweeter terminals-- It should show a reading betwwen 4 to 8 Ohms depending what is written on the back of the tweeter magnet. If you do not have a Multimeter you can take an ordinary cell/battery ( 1.5v ) from a TV remote and touch the terminals of the Horn Tweeter with the battery. + to the tweeter + ( a small red dot or mark will be there on the tweeter ) and -- to the tweeter -- . When you touch the terminals or give 1.5 volt supply the tweeter will make a scratching noise.
If you do not hear the scratching noise - it indicates a blown tweeter coil and will need replacement.See link below for spares:-

But if it does, you are in trouble and will need professional help from a electronic technician.
Could be blown HF Amplifier, suspect the crossover last. They seldom fail.

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...


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.

Replacement tweeters for Eyris 1


If any new readers are seeking the same advice, then as at Feb 2016, replacements are available from Real Electronics in the UK, 08452 307 747 - this info from the service line at Tannoy. £63.21 + VAT + delivery. Part no 7900 0621

Much of the advice above is not applicable to the Eyris, folks seem to be posting generic solutions.

Unbolt the hex bolts at the rear of the tweeter assembly. With a screwdriver or similar, push the threaded rods forward to move the front portion of the tweeter housing free from the cabinet. The amount of flexibility in the cables may vary, and some users may have to remove the terminal block (hex bolts again) on the rear, and remove the acoustic wadding to gain flex in the cables.

There are three terminals on the tweeter, with push-fit spade connections. Green for Earth, red/black for signal. Disconnect these, pull tweeter forward, remove threaded rods.

Reassembly is the reversal of removal. Ensure all cables go in same places, etc. etc.
