Compared to other highly regarded speakers
The two plots are not really comparable, unfortunately.

We dont have much of ATC from Klippel to compare than this
Still not comparable. The time scale on this one 4ms, on the Kef's it's 14ms.
A pity really, it shouldn't be too difficult to standardise these plots the way Stereophile do theirs...
These two pictures show better results from ATC. KEF has much longer resonant trails. Look at second graph at 5 ms point. Then compare it with what you see at 4 ms for ATC.

It could be, or as most likely, music production at that era just don’t focus on bass content as most of not all consumer speakers of the era didn’t have bass at reasonable reproduction levels. So monitors being bass lacking won’t have much of an issue for the work to be done?With regards to the humped up response of the 19 and 20 model and also my mistake in not identifying the SCM16 (A?) which I never knew existed (I do know the T16 with front port however), I submit this article about the infamous Yamaha NS10.
At the end, there's a series of on-axis plots of a number of small monitors from twenty years back including the ATC 20ASL pro's which I had for a short time and which measure similarly to the 19V1 annihilated here (the active 20 had a bass-lift control though which is better calibrated in the conventional shape current version and there's also a proper sensitivity adjustment/switch if I see the rear pic better). Even the fondly remembered Harbeth designed HHB 'Circle' models tested had an upper mid lift too. Many of these were used in small studios (home or otherwise) and perhaps placed tight to the wall behind them?

Hi, Would you say that ATC SCM 19A are V shaped in sound? Which in your opinion is the better of the two speakers between ATC SCM19A and 40A? Thanks.The V shaped ATC aren't magical :/
I can '' found '' only one graph, the 40a looks very fine...if you like that well done ''W'' sounds signature it's fineHi, Would you say that ATC SCM 19A are V shaped in sound? Which in your opinion is the better of the two speakers between ATC SCM19A and 40A? Thanks.
Hi, Can you help? My listening space measures 19.5ft long x 11.5ft wide x 10-14ft high. Which in your opinion is the better of the two speakers between ATC SCM19A and 40A in this space for all genres of music? Can I use a pair of SCM19A with a subwoofer and get better results than the 40A? Thanks in advance.Surely the ATC boys just split the signal and feed it to some amps, then into the speakers. As far as i can tell they don't use DSP or anything advanced to split or massage the signals into shape. Maybe you could do a better job with a measurement microphone and some DSP skill?
Besides, the SCM20ASL looks not very nice, compared to the SCM19 v2. Also only two ways, don't you want to have the big mid dome?
Seattle. Just send him a message, if you need money for shipping/packaging/fuel just ask here, i can help, maybe others can too.
@hardisj (Erins Audio Corner) has a Klippel too, he is in North Alabama.
Thanks, seen a review on YouTube where the reviewer was not too happy with tweeter on the SCM40. I am wondering if it is any different on the 40A?I can '' found '' only one graph, the 40a looks very fine...
*thanks testberichte / stereoplay*
The SCM40 MK2 is like the 40A.Thanks, seen a review on YouTube where the reviewer was not too happy with tweeter on the SCM40. I am wondering if it is any different on the 40A?
SCM50ASL is what you need. Probably SCM100ASL will be still suitable.Hi, Can you help? My listening space measures 19.5ft long x 11.5ft wide x 10-14ft high.

Hi Keith, Have you taken measurements on ATC's SCM40A and what is your opinion on these? How do you compare SCM19A to SCm40A for all genres of music? Thanks.Within the next few weeks I will be taking some active 40’s in part-ex , I could run some un-sophisticated measurements if any one here is interested?
Perhaps set them up next to the customers 8Cs and compare plots?
Keith
About 9000€ a pair. Me:Looks like ATC is finally updating the SCM25s with their in-house tweeter. They seem to have modified the tweeter faceplate to make it fit in that small cabinet... Hopefully the dispersion behavior is improved somewhat from the slightly deeper waveguide loading on their in-house tweeter.
Digi, sorry didn’t see your question, I have I always encourage potential customers to keep their current speakers in situ, then I measure their set up with whatever design they wished to compare, ( predominantly D&D8cs) then we look at both sets of measurements.Hi Keith, Have you taken measurements on ATC's SCM40A and what is your opinion on these?
