atc mid...
hi there...
i have the atc scm 100sl, a 3-way using the 3" mid-dome!
its good, its the best - every larger speaker should be based on that driver.
the idear is to cover the very critical 300 - 4000 hz without any crossover.
it has mega powerhandling.
its "linear"
it has good diffussion.....
it sounds total neutral.
if i should build a speaker and use the atc dome, i would definitely
use the "original atc crossover - which have impedance correction "up and down" and 12 db slopes "up and down"
best regards,
troels

Thanks for the tips folks! The ATC is crying too loud for me, I`ll have to strangle it to fit the other divers! Mybe in a later project?
And; I`m just using the mid-dome as a "low-tweeter", that means a good 2"-dome will do the job close to perfect, better than the ATC.(-after replacing the back-chamber and a little tuning..)

Any more info about ATC dome?
Nice to see the ATC dome getting a mention here, as it is one that I have contemplated for a speaker I'm planning for after I have finished my bass cabinets.
There doesn't seem to be much info on this driver, even on the ATC website. All I can find out is that recommended XO frequency is 380 Hz, and it looks like it has its own rear chamber, so you don't need an enclosure for it. Please correct me if I'm wrong.
Troels - what do you mean by "Impedance correction "up and down"" ? Do you have any XO schematics for the driver?
Any other information appreciated.

I know the place where is dynaudio D-54Af's still on sale. Pretty good drivers!
Check www.digitex.it price was something about 250e each. they might have something else dynaudios too. They had 4 pcs left about 1-1,5 months ago.

The ATC is very hard to find out much about. Anyone else have any leads?
What's the efficiency? It's true that the website doesn't seem to have info on it. What website are you guys looking at?
Anyone know any dealers?
Sounds like with the Stage Accompany tweet and some PHL or Audax woofs that this is the DIY Audio high output speaker.

I have never seen much in the way of specs for the ATC drivers, I think they play it fairly close to their chest, as ATC prefer to sell complete systems.
I suspect the only way to get these parameters is to buy a couple and measure them, but at the moment I don't have the disposable income
The only frustration I have is that they don't go up high enough to reach the Audax HD3P gold dome tweeter, as that really needs a crossover of around 5K to work well.
Do you have any references for the Stage Accompany tweeter, Mark? It is not one I am familiar with.

Although my search of the speakers forum didn't net much, the Stage Accompany drivers have been mentioned on DIY Audio.
The jist is that even without a horn they are over 100db efficient,
sound fantastic, and handle tons of power. VERY expensive: $600 ea I believe
http://www.stageaccompany.com/usa/
http://www.stageaccompany.com/
So the company is similar to ATC in that their major business is sound systems put together with their own drivers.
However I think they both will sell the drivers, it is just a very small part of their business so isn't well documented.
Maybe this is a good project for us to look into
Esg2 tweeter is efficient but how much power can it take?
@ $200, a lot more appealing though!

TAD PT-R9's are very highly regarded, anyone know anytthing?

It sounds like both Stage Accompany and Audax have been approaching the same problem from slightly different angles

Without hearing them, it's hard to say, ( I have always been wary of the directionality of ribbons), but it looks like a well engineered driver, and I like their philosophy as I read their web pages.
I agree, this could be the ultimate high sensitivity system here, but we need to think about the bottom end!
Troels, could you post a schematic?

These are huge monitors that use the Stage Accompany driver
One of the designers is Stig Eric Tangen who designed the Almighty Subwoofer

I guess something like one of these would be pretty cool......

Hi Test Pilot,
I have two D54 AF almost mint condition that I would sell, I bought them arround 15 years ago and did some testing with them but decided not to use them because the sensitivity was to high for my system and was a 3 way project. They are still in it's original boxes.
Anyone interested?

Yes it is realy hard to find any info of the org. filters for the ATC SM75-150S dome - Do any one no where we can find this filter ?
I have find 3 person who use this driver:
