There is no ATC SCM150ASL Pro review or frequency response curve.

Smaller ATC speakers measures pretty good too.

Here are the measurements I did for my ATC SCM11:

I'm amazed someone can so confidently proclaim ATC's engineering superiority from intuition and anecdotal experience when they can't even see a directivity mismatch stare them in the face of the measurements they make

Hello Mr. “Small-errors-in-the-directivity-screamer”, if you have a listening environment where those small errors are heard, you have much larger problems to solve. ;)

When you get your room sorted, you will realize that low distortion is way more important.

I'm not really seeing a di mismatch in that data. I see diffraction but not a di mismatch.

This threads gonna turn into a repeat of the other one here, which has like 250+ pages of people going in circles. I wouldn't even bother caring about ATC, invest your time, energy, and possibly money into researching brands who are up to date in terms of transparency.
 
Did he give a reason for that?
It was the usual bluster, ‘measurements don’t matter, our customers aren’t interested, measurements don’t entirely explain, we have sold lots of them’ etc etc.
Usual stuff I hear it all the time.
A comprehensive set of measurements and we can discuss the speaker but until them what’s the point.

Please provide a link to where he said that “measurements don’t matter”. If what you are saying isn't true, you don't show respect to ASR which is supposed to be a fact-based forum.

I believe this was a conversation that was had, so no link I suspect.
 
Why do you believe that a UK based dealer would have a conversation with the US distributor?

It's 2024 my dude, you know you can email people in different countries right?

Talking about measurements Eversolo's SINAD (it's 102dB and NOT 113dB) is still to be corrected at your web page.
 
Not a conversation an ATC thread on Gearslutz, I asked him why he hasn’t sent a speaker to Erin, I will try and track it down or ask him yourself and post his reply.

It shouldn't be that hard to find if it was a conversation with you. I’m looking forward to see the “measurements don’t matter” quote.

I’ll mention it to @mirror88 its still up on their site,

Dynamic and Detailed Representation​

The AMP-F10 boasts an excellent signal-to-noise ratio of 113dB, ensuring that musical details are preserved from the quietest passages to the most dynamic peaks. From the elegance of classical to the intensity of rock, you’ll capture every nuance with impressive clarity and depth, making every genre come alive.

The bold is SNR,not SINAD.
SINAD is distortion+noise and since they state 0.008% for THD it can't be over 102dB by all means.
 

He doesn't say that “measurements don't matter”, he clearly says they don't tell you everything of how a speaker sounds and how it performs as a studio tool.

Brad Lunde says:
“Kieth: The hi fi critic graphs posted above are exactly why I will never do that. Measurements are NOT always right, NOT always perfect representations of how a speaker sounds or performs or satisfies a clients needs. There are many ways to get an inaccurate representation or interpretation, exactly as the post above by i.shadrin and the follow up post by qpbm illustrates. And that's just the tip of the iceberg.

Kieth you've invested 100% in measurements. For you, that explains all you need to know. ATC and I are 100% invested in answers to different questions: Does it translate? Can I hear details that I need to address? Can I stand to work in front of it long hours? Is it reliable under my conditions? Can I repair it ? Will it make me more money by speeding up my work or enabling me to do better work? These are issues my customers care about. Measurements say zero about any of that.

Except for the last part, where he lists seven things and says "Measurements say zero about any of that."
  1. Translate
  2. Hear details
  3. Stand to work in front of it for hours
  4. Reliable
  5. Repairable
  6. Speed up work
  7. Better work
I agree acoustic measurements wont tell us about (4) and (5). I think the rest are comprehensively covered by measurements.

The whole "measurements say zero about any of that is kind of the same thing as saying they don't matter, or at least they don't understand how they correlate to what we hear. I'm sure they do understand but they have a user base they need to cater to so they can sell speakers. They're smart to capitalize on the mysticism so many buy into.

The second paragraph is just there to tick all the buzzwords that ignorant engineers buy into all the time, I know some people think people involved in mixing are by default well educated on this stuff but they usually are not. If anything they're often just another market to pander to. I would know, I do mix work but I'm thankfully educated enough on loud speakers that I don't fall for it. If they really stood behind what they're saying here, they would provide data and be able to show what tuning decisions they made led to achieving their design goals. They'd be able to tell what metrics help you "speed up your work" or "stand to work in front of the speaker for long hours".

I could go on and on about everything wrong with what they said but there's no point. People who already know don't need to hear it and people who don't aren't going to listen.

I agree acoustic measurements wont tell us about (4) and (5). I think the rest are comprehensively covered by measurements.

1. How a monitor work for a person is highly subjective. One must use it to know, just looking at the measurements will not tell you this.

2. How easy it is to details, layering, reverb tails, and so on has likely much to do with low distortion, and especially so in the midrange where pretty much everything in a mix overlaps. It should be seen in the measurements, but it is probably better to actually hear how the loudspeaker performs in real use.

3. This is also likely highly subjective, what doesn’t cause listening fatigue for one person may do so for the next guy. Using it for long time during work for 8-10 hours a day will tell you this.

4 and 5. Reliability and easily repairable is very important for someone dependent on the work tools for his work. ATC has a long and good track record of this.

6. This is related to many of the above points. As in point 2, the better the audio engineer can hear all the details, layering, and such, the faster he will be able to make the right decisions faster. Point 3 prevents extended pauses, and reliability and easily repairable is obviously a good thing for speed of work.

7. Everything above will lead to better work.

Most of the above points are hard to know just by looking at measurements.
