Monitor Audio Tweeter Needed

Happy new year,

I have an old pair of Monitor Audio Silver 3i with a damaged tweeter. Don't ask how this happened......it did and I ma left with the results you see.

The options that I have thought of are

A) Get a replacement diaphragm / voice coil and try a repair. The problem with this is I cannot see how the assembly will come apart to do the replacement.

B) Try finding a replacement on eBay or directly from Monitor Audio. None on ebay now and waiting to see what Monitor says. As this is an older model I do not have high hopes on getting a replacement from the manufacturer.

C) Try an "upgrade" or modification of some kind that ends with good results.

All advice, thoughts and insight welcome -

Thanks

Time for a massive upgrade.

Superior specs, Inexpensive, Smooth response, High power, good sensitivity.

Parts Express does not have a category for "ring radiator"...does it go by another name?

Sure they do just do a search for ring radiator tweeter.

That said, one cannot just slap in any old replacement tweeter without knowing the Thiele/Small parameters of the original in order to see if a replacement is a match.

Have replaced almost 40 speaker system tweeters with Ring Radiators.

Customers are blown away, New life for old speakers.

Please provide additional info on what driver this is and where to find it. Thanks Chris

Yes, that is always my first thought when replacing any speaker. That said, I thought Thiele/Small parameters had more to do with movement of a cone and its effect within the cabinet space. In the case of a closed back tweeter this might have little (no) effect but the crossover design could certainly effect n the functionality of the tweeter. If I have gotten this wrong please excuse me as I have not read much on the design of speakers / cabinets in over 30 years and could have mixed up, or forgotten something. I am just going by my memory.......which is less than perfect.

Use a piece of strong adhesive tape to pull the dome back out.

I have also used this method as well as the vacuum method. Both can work well. Unfortunately these are composed of metal and are MUCH stronger than any paper, silk or other dust caps. Once dented, you are dealing with the properties of dented metal and normal methods to pull out the dent will not work. On top of all that, the surround is also damaged so there is physical mechanical damage to the the tweeter. Thanks for your thoughts -

Tape and vacume has worked well in most cases for me also.
I have alao used very thin needles to pull out stubborn dust cap dents.
It leaves very small holes though that I just put a very small dab of gue on.
It was better looking than a big mashed in dust cap.
