20 Most Recent Tannoy Mercury MX3-M System Questions & Answers

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 George,

You may be able to pull them out using tape. That is sellotape then gently pull .They should pop out like
a dented car panel. My understanding is these domes really protect moving coil from dust so should not affect sound. Worst case swop the tweeter.
Ive just bought a pair of revolution 3 with same "fault" so I will let you know how I get on .I am in Electronics trade as profession. It may be possible to gently remove dome using a surgical blade then popping out and gluing on with PVA / Latex glue coloured with black ink if you dont like white appearance.

It is sometimes possible to pull out using fine sewing needle push in then gently pull out as if removing a spell from your finger.

Hope this helps

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.

The speakers consist of an induction coil, and a magnet attached to the cone. You have damaged something internally or the cone itself. Speakers don't have fuses unless they are powered speakers with mains input and an amplifier. You need the speaker repaired or replaced.

If the company say they are no longer made, then it's unlikely you will find replacements in any electrical parts supplier. If you still want to use the unit then you will have to look around for one on places like e-bay, which might be faulty elsewhere , but have a working tweeter. A search on e-bay itself might even reveal a spare tweeter! Or a second hand that's cheap to replace the one you have. At least you will another set of spares (except tweeter of course) for the new one!

Two suggestions: They're old how old I can't tell I'd go to their web sight and see what you can find. Sorry that's best I can do.

I would say from your description that the tweeters are blown. Can you take the speaker that sounds good and swap it out with one that sounds bad. If you do that and the good one still sounds good. You have a tweeter problem. And they would need to be replaced.
