Repairing expensive speakers

Damn. They saw you coming.

Two 1500W ElectroVoice Live performance drivers will solve your problem forever, and cost less in the long run likely.

$300 just for a single cone!? Did they spike your coffee with "roofees"?

Anyway, there must be a full replacement that will yield similar or better performance. Worth buying a couple of cheap auto jobs just to prove it.

Look on Ebay!

I would talk to all the proffesional shops to see if anybody can do something. Replacing the units will not work with current crossover to the built in tweeter inside the woofer. The orginal sound is not likely to be had. A typical professional setup will not sound good near field.

Other than that, I would just start from scratch.

you might try calling "Van L Speakerworks" in Chicago. They've been rebuilding speakers here for quite some time.

I would never consider even buying such a driver, much less considering one to be actually worth "several thousand dollars".

What a sad choice to have made for a system to begin with.

How some dope injected an integrated driver arrangement like that into the "audiophile realm" is beyond me, if that is what this guy thinks he is.

Everyone (the industry) knows that segregated drivers for different segments of the human audible spectrum is best. None of the real makers use such a paradigm as integrating two 'bands' of said spectrum into a single driver.

Jeez... this isn't car audio. There is no need to attempt to consolidate space. Several thousand dollars indeed.

I should send a bill for several thousand dollars for giving the advice. Ha!

Before you get too carried away try Googling "Tannoy Dual Concentric" so at least you know a little more about the technology you are denigrating.

I once had a pair of Tannoy Ardens (15" Dual Concentric driver) and they were probably the best sounding speakers I've ever had (including the Quad Electrostatics and the Spendor BC2s. Then I grew up (damn!) and had to spend my money on feeding the kids etc.

(mind you $5k seems steep - I paid £400 for the Ardens (pair in cabinets) but it was in about 1975.)

Still not impressed.

Besides, the cabinets mean more to the sound than the drivers.

If one is spending several thousand dollars each for a driver, one would think that one would spend a bit more time deciding what value, quality, durability, etc. matters.

Looks to me as if the cone 'assembly' has more mass than a normal driver, and that has to hit it in the low end, where this driver matters.

Best for what. Some very best electrostatics cover all above 100 Hz. Some real makers DO use a single mechanism, and for good reason. Single mechanisms require more engineering, and more money.

We are preserving spacial imaging and phase coherence even off center.

I see Celestion makes a 12 inch model but I don't see a 15.

greg

Normal what. High mass means lower response. Efficiency is not as important as lower response.

greg

"Everyone knows" is a clue that someone is a liar. Lemme see: take the sound of a tuba or cello; SINGLE source, NOT sound spectrum broken up into "segments". Just _try_ to faithfully reproduce the sound from one of those (or other sources) with that scatter "system" that "everyone knows" is best..

Yes, but the discussion is about how WE reproduce them, and in such cases, with our primitive (to a tuba) transducers, we most certainly do break it up into bands that satisfy the physical limitations of the transducer designs we use for each of those bands.

Try again. You lost that one, and nobody lied about a goddamned thing.

Your brain is scattered. Just look at what the best of the best are putting out there, ya dope.

Suggest you send out the original, to ensure that the replacement is a proper fit. Sounds reasonable to me, considering western hemisphere costs and your original investment.

Tch tch, Archi....You were doing so well. What happened? Did that boil on the roof of your mouth finally break? That's what happens when you refuse treatment for your Syphilis. Why do you find it so difficult to accept good advice?

We're praying for ya, buddy. Jesus loves YOU.

Have you tried a plasma speaker (hiss suitably muffled)?

No, but I have a couple of flat panel jobs.

I still remember when that (flat) was new technology back in the mid seventies, and only one maker had/made them.

I saw some odd 'Tesla' hardware looking speakers in the high end magazines that were almost all the way up to the ceiling, and it looked like a cone shaped thingy (that's what *she* said). :-)

I starting by calling Tannoy that reply the following:

"We don't have the kit but you may get it from company x. Then send the complete assembly to the closest Tannoy service center (200 miles from my residence) and we will do the reconing. We don't recommend changing the coil."

The installation of the kit is easy. It is self center and it doesn't have play adjustments.

In order to do a god job, I should order 2 cone kits from England but the total cost including transportation, duty an taxes will be more than $1k.

The speaker with less damage has about 6 turns dislocated as a group from the rest of the coil that looks solid. I am going to read again your recommendations about the glue, paint the 2" tube with that glue and slide the 6 turns group into their previous position.

If this works I may try to rewind the other coil "fat chance"

Then I may order one or two kits from England and do the reconing myself.

Thanks for all your help.

If the cone assembly includes the voice coil that is a pretty good deal, i might even buy extras. Since you have done this kind of thing before i presume that you have the tools.

You could probably find stronger adhesives that are still repairable, but i bet they will be rather expensive and may be shipped frozen (with months limited shelf life, and just minutes pot life).

Your outlook on everything is so obviously bent toward pessimism.
