Yes that’s probably it and those listeners and ‘engineers’ probably wouldn’t understand them anyway.Maybe they don’t think the opinion of web forum users is important. Listeners and engineers using their speakers are who they need to worry about…

The pertinent question is, why haven’t ATC measured their speakers themselves or sent them to be measured by an independent third party.

It depends on the selling points and advertisement (of which no one is innocent)That’s dandy but some contemporary manufacturers actually measure and publish those measurements themselves.

What doesn't measure well in their speakers, do you have some measurments to show we're not aware of ?Let's be realistic here.
ATC doesn't measure great by Toole/Olive standards: German mags showed this ages ago and ATC knows it. But they also know their speakers sell. People have loved that sound since the '80s, and changing it risks losing loyal customers without necessarily gaining new ones.
The wise move? Start a new line that aligns with modern research, while keeping the classic designs that are beloved everywhere except ASR. Let both designs compete with each other under the same brand name.
I am looking at this from a perspective a sales engineer here.
THEY DO Keith!!!!! - Measure their own speakers I mean... I had witness of two plots of my own 100As, once when manufactured and filed away and the second time when an amp pack developed a fault and one speaker was returned for repair in the back of our branche's estate car (I always enjoyed an excuse to visit the factory and meet the main men there back then...). The two plots, three years apart, were thickness of the pen identical...The pertinent question is, why haven’t ATC measured their speakers themselves or sent them to be measured by an independent third party.

Hmm, I think this way they would sell more units in total. But they want this? I don't think so.The wise move?

Troels Gravesen did measure SM75-150 by their own (well, lacks burst decay, and most importantly distortion, but considering what they measure in the CSD Waterfall and how they are build with two coils to have a straight excursion, I doubt they will measure bad).
I don't see why they don't show measurments either, but why don't ask them straight by sending them an email to ask ?
There's nothing to solve here, no mystery. Anselm Goertz measured the ATC SCM 25 who is one of the most reliable sources for speaker measurements on the internet. Amir measured the SCM 19. You can see off-axis measurements SCM50 above. And beyond the measurements, anyone who understands basic speaker design knows that a 2 or 3-way without a waveguide around the tweeter simply can't meet the requirements set by Toole's research. Physics won't allow it. It's not opinion, it's geometry.ATC should send a pair of active SCM50 to Amir
It will solve all the mystery
What year is this ?View attachment 507596
SCM50. Messy off-axis even from 60 degrees angle. Directivity index is obviously messed up from 4khz and up. We discussed this before, soft domes can't perform well above 3-4khz, their dispersion characteristics change after 2khz and they start beaming.

SCM 25. Not bad, not great either. Based on Olive/Toole research performs worse than any Neumann or Genelec.
View attachment 507598
SCM 40. Even from 30 degrees angle, the tweeter starts beaming in directivity. Very messy.
SCM 19 was measured by Amir a couple years ago.
SCM 100 measurements are also available but I am lazy to dig deep to find them.

Well, you're right that Studio with large ATCs are mostly used to impress clients, producers, labels etc..., but that's also true for other companies. Warren Huart from Produce Like a Pro always get that feedback from Mix engineers, large speakers are mostly used when the Producer or label is coming to make the last validation to go to mastering, and obviously, it's the last mixer's check.The current head of the company (son of Billy) isn't an 'audio trained' person I gather (I was told he's a lawyer by trade), but no idea on the sales director or the current design chappie as to how much influence they have on company trajectory. The 100A SE version mentioned above, went I believe, back to a fully discrete active crossover hinged off or plugged into the main amp board and the audiophool argument was that it would perform better than the chip-based active crossover section a bod interested in buying them and contacting me for input as he knew I'd owned and loved 100As, refused to accept that the chips used may actually offer lower noise and distortion than the complex discrete electronics on a daughter board with extra wiring... Still, at the time, it helped justify the extra cost (pushing 50% I recall).
I was told even thirty years ago, that big studios were closing down and the use of large soffit-mounted monitors was to impress clients rather than full-scale general use. ATC have had to diversify it seems, so lavishly veneered tower versions seems to be where it's at, especially in the lucrative far eastern market. I had to leave the Facebook ATC group because it was full of pics of dem rooms like over-done recording studios and a pair of huge usually passive ATCs with large valve amps by the dozenplaced as a shrine in between them...
P.S. Until the mid 90s or so, ATC used a Vifa soft some with ATC front plate for most, with the large Audax? in the 200 and 300 models. They changed it when said tweeters was discontinued (I believe) and at the time, existing models couldn't be drop-in retro-fitted (my 20ASL Pros with curvy cabs needed new baffles I was told by their sales manager and they didn't seem very interested frankly, which was a change from previous regimes there). I seem to recall the current tweeter can be fitted, but best to ask the factory here.
What's left and what's right?
Have you ever been in a room with a pair of the 50s? I’ve never met Amir,probably never will,but I’ll pretty much guarantee you he isn’t carrying one of the 50s around and sticking it on a klippel without serious long term injury,it’s not just the excessive weight,they’re just bloody hard to pick up.ATC should send a pair of active SCM50 to Amir
It will solve all the mystery
Though, in Mastering they're vastly used (PresentDayProduction before switching to their in-house made speakers), The Sterling Sound, etc...
I was thinking also of the large multi-driver monitors from many international makers here, not just ATC... Mastering rooms tend I believe, to use something a little smaller, such as B&W N802 and one mastering chap I know of, used ATC 100As when based in his home studio in Skye (the remoteness did no harm as files were sent to him for mastering - I believe he's emigrated east now and not sure if he's working as he's a few years older than I).Well, you're right that Studio with large ATCs are mostly used to impress clients, producers, labels etc..., but that's also true for other companies.
