Inverted(puhed in)tweeter Hi,just bought a bargain pair of Tannoy mercury Mx3 speakers the problem is that the tweeter cones have been pushed in. Ihave tried to **** them out but there seems to be a vacum behind them. any ideas? I would be greatfull for any help Thanks George

Speaker impedance of 8 ohms suggests home hifi use though the stated performance is typical of a bookshelf speaker, designed to be at the "reasonable" end of the market - reasonable performance, reasonable quality, reasonable cost and suitable for a wide range of volume settings at the lower end of the scale...

Constructor catalogues generally offer a wide range of loudspeaker drive units including tweeters and mostly provide pictures. If you want to avoid modifying anything simply choose one that looks like yours and then check the description fits.

Try Parts Express website.

check to see if you can find it on parts-express.com that's where I get all my speaker stuff

The oily coating you see is a damping compound applied by the company to make the sound smooth and less edgy or harsh.Cheaper speakers most of the time sound bright and progressing on to a Hi Fi speakers take time getting used to.In the long run you will realize you will get lesser ear fatigue listening to good Hi Fi speakers .
One test to confirm if the tweeters are working all right is to play a blank FM channel with the FM mute released ( FM mode on Mono ). Turn up the Amplifier volume and you will hear a loud hiss ( like standing next to a waterfall ). Turn the balance control towards each speaker and see if they sound identical.
Next remove the grill and cup the dome tweeter with your hand with out touching the dome itself to block the hi frequency sound, it should sound dull. And when you remove your hand should sound hissy and sharp.Try to do this with the balance control turned towards your speaker.
Sound is very subjective and personnel like taste, don't let anybody talk you into deciding which is better for you.

In audio, beauty is in the ear of the beholder.

If you're NOT bi-amping or bi-wiring them, leave the jumpers on.

Unless you were already stating with junk for electronics there is not a lot of evidence that either of those schemes would result in anything audibly superior, but they WILL cost more due to the expense for extra amplifier channels and boutique speaker wire.

Google it.

hi,
check the tweeter and mid range. its coil may become faulty.
for checking the speakers carefully remove the speakers one by one, remove its connections.
and check the speakers with a AAA cell. is it producing cracking sound. if not the speakers coils are burned.
ok

If you found second hand 605s you can swap entire sub speaker. Your other option is check your local yellow pages for a pro audio repair shop that does re-coning. Re-coning is a specialty operation and it's not a procedure for the novice. You can also check online for re-coning services.

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.

On the images on Google for them there are no extra wires. Where are the wires on them? Do all the drive units work?
If the wires are for the super tweeter. Then looking around at the Google images it should be possible to unscrew the 4 screws holding the tweeters on top and you should be able to push the wires back inside the unit, if they are not connected to anything. Or at least see where they do connect.

hi i solved the problem with the super tweeters. two of them didnt go so i pulled them apart and got the voice coil and unwound it enough to solder it back on to the terminals.they both go excellent now took about a hour well worth the time.
