ATC SCM7 vs SCM11 ? Which one would you choose?


Hello. I'm new to ATC speakers sound but I have read many reviews about both speakers praising them for their great sound. I own a pair of KEF LS50 but even though I find they sound fantastic, I would like to go the extra mile and upgrade them to something better. I've read that the ATCs can handle more musical genres than the LS50s and that's important for me because I don't listen to audiophile recordings all the time but also 80s and 90s pop and rock that aren't known for having good recordings and you can find really bad recordings.

I know the SCM19 it's supposed to be the best of the entry level line but I wouldn't like to try the ATC sound paying $4,000 so my options are the SCM7 and the SCM11. If I really like the sound then in a near future I could upgrade to the SCM19 and use the other speakers in another room or sell them, BUT, in the meantime, do you think there is a great sonic difference between the 7 and the 11? The difference in price is $500.

The frequency response of the 7 is 60-22 and the 11 is 56-22 but specs sometimes doesn't mean that much in practical terms. Would the SCM7 gave me a much lesser experience than the SCM11?

Thank you very much for all your insight, best regards,

I'm currently using the ATC ACM 11 in a 11.5 X 12 room to great effect. I would recommend the 11s over the 7 for your room.
Please excuse the double post. Hi. I would like to thank everybody for their helpful answers and specially to all of those who recommended me ATC speakers. After reading your opinions and others from similar forums, since no SCM11 speakers where available at the moment (3 weeks ago) I found a pair of SCM7 speakers (V.3) used but in perfect condition. WOW, I've heard many speakers before, including my KEF R7 and LS50 speakers, and even though it sounds cliche, I can really say like other forum members had said, that these ATC are in a completely different league of their own and are BY FAR and NOT EVEN CLOSE than others, the BEST speakers I've heard in my life.
With my first hearings and comparing them with my LS50s, I thought the sound produced by the LS50 was linear, I mean, all the instruments sound at the same volume level but in their different positions and with the SCM7, some instruments sound specially louder than the voices but in a very nice way, almost 3 dimensional where I could "touch" the instruments.
After more hearings I still think there is like a V shape or something like that where voices sound a little less loud than the other instruments but in other songs the volume is equally distributed, BUT, that's just an observation. The main feeling with the SCM7 is that they provide an uncanny neutral sound WITHOUT being fatiguing at the same time. Everything sounds "like the real thing", sometimes "too close to reality" but without any harshness and almost all kind of songs from all kind of recordings sound great.
ONE GREAT THING these SCM7 speakers also has is that they provide a superb soundstage and instruments separation way beyond their physical space.
Anyway, this "review" is the least technical one you might find because, in plain words, the sound they deliver is MAGICAL, there's no better word that come to mind. They make me feel a special joy because EVERY SONG I've heard, even those I've been hearing since I was a teen in 1988-1989 and have been hearing through all the years through a lot of car speakers, home speakers, headphones, etc, SOUND ABSOLUTELY NEW when heard with the SCM7. It's the excitement you could get if, suddenly, all your favorite movies could be seen, in a future, in full 8 or 16K with 3D, I mean, a complete revelation that makes you PLAY and TOUCH the music if you know what I mean.
These SCM7 speakers have been an unparalleled sonic revelation.
My search for the perfect speaker is over, I think. From now on, I'll be concentrating and other ATC models as an upgrade.
Best regards,
I’m with you! I had a pair of Scm7’s 2 months ago.  Sold them for some tylers that can play at the levelsI like.

The ATC’s were one of my favorites though.  They scaled dynamics and made music have a certain boogie or swing to it that I hadn’t experienced in my listening room before.  I had a few “aha” moments where I heard a very familiar song (metallica/rush/pink floyd) and thought to myself “okay, thats how that song is supposed to sound”.  Thats a strange revelation to have.

Hopefully I’m able to move up the ATC line someday.  Those dome midranges are supposed to be magical
Always choose the largest size that the room can accommodate with the exception of large monsters with 12" or larger drivers.
