Atc loudspeakers scm20sl pair

The SCM20 has been on the drawing board for nearly four years, though eagle-eyed and eared show visitors will have seen and heard prototypes from various points in the model's evolution. ATC wisely chose to demonstrate these prototypes over the past two years, not to antagonize but to tantalize. Only by showing that the company was serious about offering a small system could it prevent space-shy, would-be ATC owners from shopping elsewhere in despair. The virtues present in the SCM20 include every one of the company's signature techniques bar the option for active versions; the box is simply too small to contain one of the company's onboard amplifiers. That aside, the similarity to the larger, dearer beasts is absolute, beginning with the same 25mm viscous damped fabric dome tweeter sourced from Vifa in Denmark.

ATC speakers - First impressions


The tonal balance of the speakers is excellent. The bass is tight, articulate and quick. And it's a sealed box design standing about 24" from rear wall. The timing and control is terrific. If the end of a song has a long diminishing end to it the speaker does not truncate it but carries it through till there is no signal left. That's accuracy.

The dynamics is impressive. Turn up the volume and the music simply gets louder without distortion. I also heard that the amplified version of these speakers is best. I would like to hear them someday.

Maybe at the NY Audio show in Nov. LOG IN. This is a fairly new model and may be a bit of a departure from their classic sound. At the show in Newport last weekend, I was quite taken by these speakers.

I went back the next day and heard the same things that I liked about them, but a couple of red flags also went up: Microdynamics — not sure these speakers do them well and microdynamics are critical to communicating inflection and nuance and to making music sound alive Imaging, specifically wrt depth. Nothing much outside of the plane of the speakers, so recording venue info is not there and even instrument and vocal body may suffer a bit. Were these shortcomings of setup or associated gear, or is this what ATC does?

Edit Delete. The least distortion I've ever heard in a speaker but they need a lot of juice so SET need not apply. Lindisfarne is absolutely correct. Lots of really good power otherwise you are wasting your time and lots of money. Very revealing of any flaws in the system to include cabling. I have owned SCM and have heard most others.

There is nothing that the ATC cannot do. They are seriously among the absolute best speakers out there. They sound like whatever is there in the recording and what is being fed to it via the electronics in the chain. You need really good amplifiers and sky is the limit.

Look at Symphonic line amps if you are looking for the depth and width of soundstage along with a very finely nuanced and liquid sound. You can even consider an active SCM40 which in my opinion is the best thing to do. I own a pair of the SCM 19's and am in love with the gorgeous sound. Yeah, the Lux has plenty of headroom, but the supposedly power-hungry ATC's still sound magical. And, YES, they sure are accurate!

Don't expect any artificial lushness with anything made by ATC; they tell it like it is. Powered by ATC electronics they were great and really held their own compared to some of the outrageous gear featured in many of the rooms! Regards, Oran. I worked for an ATC dealer a while back, and we didn't carry the 40s but I got to hear the 20s and 50s quite a bit while I was there. To me, the midrange is about the best I've ever heard in terms of power, resolution, and an utter lack of any distortion or strain.

Where I found them to fall a little short was with respect to holographic 3D imaging. It's not that they don't image well, it's just that compared to other what I'll call the more "audiophile" oriented brands they don't portray or some would say exaggerate things like depth or width of the soundstage, and I'd agree the venue info is a little less apparent as well. Again, this is just relative to speakers that excel in these particular areas.

Perhaps the new 40s improve in these areas if they represent an evolution of the house sound, but I have no idea. Can't say I noticed anything regarding micro dynamics, but we usually demoed them with more dynamic music so that might be why. I really can't fault them in any other areas. Great overall speakers, and I wish they had more exposure here in the U. ATC do not use the latest and greatest of the tweeters.

So speakers which employ those do tend to have more atmosphere but to make the whole package sound as natural is not easy and that is why most of those speakers get into the hi-fish category. ATC uses their own traditional dome tweeter which is well extended but not like khz and all, hence they probably do not do those extra-terrestrial like sound. What ATC presents is a full range sound that is extremely coherent, uncolored and dynamic.

When you hear it you know everything else is flawed. Great responses, everybody. Thank you. Not sure how it compares to whatever they were using before. IMO depth is nearly entirely a psychoacoustic construct that depends on how far away from the front wall the speakers are.

Further you put them, more perception of depth you have. Resolution wise which covers off microdynamics I think these are without peer at their price point.

I'm not a speaker designer but I think it is because they are using extremely beefy drivers large magnets with underhung coils. Take a look at the size of the mid-woofer in the SCM Technically this could be because the mid-woofer in the 19 is the SL "Super Linear" version, whereas the woofer in the 40 is their standard version.

May also be partially due to the increased complexity of the passive crossover in the They have the same sonic signature but the 40s have a much "weightier" presentation. ATC speakers have three main strengths: neutrality, resolution and bass quality. Bass is tight and articulate due to either sealed box or a very low Q port tuning in their larger speakers.

I would venture to guess they are not changing their house sound now after decades. Small refinements typically from the Pro market. Acousticfrontiers, I have had a fair share of exposure to the 40, 19 and also the SCM It is true that the 19 and 20 feels lighter and quicker a bit but they somehow just do not have the midrange palpability of the 40 due to that amazing dome mid range driver of the Regarding bass, it is both ways, the 40 goes deeper and fills a bigger place more elegantly while sounding very tight and defined, where as the 19 and 20 are somewhat more lean and agile.

It is going to be a matter of preference and room size IMO. Great speakers, but from what I've heard and what ATC owners have to say, is that active is the ticket. Pani Very much agree with your conclusions.

They are both exceptional speakers, very similar tonality, but different presentations. Like you said, pick one based on your preferences! I have long believed this to be true. If your brain via your eyes doesn't perceive space for the musicians to occupy behind the speakers, your ears will not perceive soundstage depth through your audio system. At least that's what I believe. Unless you've pulled your speakers out into the middle of the room even as an experiment , I don't believe you've experienced the depth your speakers are capable of.

Thank you! They all sound very similar even active vs passive. As you go larger and go active the clarity and distortion drops while the SPL capability increases to truly incredible dynamic levels. Recently I simplified to their active elliptical design which has a 15" woofer. All three drivers are entirely made in house by ATC. The tweeter is a new in house design and has no Ferrofluid - it has a double spider - perhaps the only tweeter using this design. As others have mentioned, the magic is in the bass and mid range with ATC - the bass and mid range are so clean and tangible that this is immediately easily noticeable versus other speakers.

The new tweeter is designed and built in house by ATC like all their drivers and is only available on very recent models and it is outstanding but the tweeter improvement vs other speakers is not of the same order of magnitude noticeable significant improvement as the bass and mid range.

Active is such a no brainer - it allows amps to work within a limited bandwidth and without the heavy load of a passive lossy crossover - the design is just an order of magnitude better than the traditional approach in terms of low distortion and driver integration provided active is done well as it is possible to mess up any design approach. I have my 19's fairly far from back wall for a small room,10' by They do need some volume They were pretty impressive.

You mentioned the midrange and driver integration was better on the SCM 40 but that you still thought the DIs were the better speaker. In what way? You wrote: " As you go larger and go active the clarity and distortion drops Clarity increases and distortion drops ATC has been on my short list for some time now Anyone else with first hand experience with their active line?

I indeed meant to say clarity increases and distortion drops as you go to larger models but the overall sound remains totally consistent. The super version stronger drive motor of their 3 inch dome mid range combined with the active amplification and phase aligned active crossover is really worth aiming for if you have the means - all the 50 and larger active models have this.

Alternatively, passive 20 or 19 and a JL subwoofer might be a sensible way to go on a tighter budget. I have a pair of custom built active ASLs that I bought from an orchestra. It was part of a portable stage setup.

Just patiently wait for SCM40 v2's if you like the ATC sound, the ATC SCM20SL (bought 'em, still have 'em) — different speakers in so.

ATC Loudspeakers SCM20SL - Pair


Both the mid-bass driver and tweeter are handmade by ATC. Together, they form the basis for an exceptional 2-way monitor loudspeaker. Integrating the drivers is a 2 nd order crossover featuring oversize air-core inductors which are wound in-house by ATC. Capacitors are all high voltage polypropylene film types which deliver outstanding reliability and minimal losses. The SCM20 cabinet is constructed to be heavy and inert, with bitumastic damping panels deployed at critical positions to minimise cabinet colouration. However, their neutral fidelity, outstanding resolution and modest load impedance also ensures excellent compatibility with a very wide range of quality electronics. SCM20 User Manual.

Cabinets show a bit of wear but look great in the dark red. You don't get much bass out of a small monitor. The bass could be a touch. Use Hifi Shark to monitor pricing and global availability. The sounds like a much bigger, more dynamic version of the 7s with scads more bass. Said yet another way, the top of the line speakers aren't of a "better.

Rachel Cramond Monday, October 29, Despite a lifetime's involvement with loudspeakers, their design, modus operandi, application and performance, I still find myself hesitating when asked to prognosticate on how a newcomer will be regarded ten years from its birth. Of course it's easy to see that some will have no more than a brief moment of glory, but who would have been bold enough to predict that Quad's first electrostatic would run and run, substantially unchanged, for over 30 years? The exception that proves the rule? Well possibly; much more common are the basically sound designs which lend themselves to a continuing process of development. It could well be that we have a further example in the ATC model which is at the heart of this report.

This review might not sit well with some of my audiophile friends. Truth be told, once upon a time I would have included myself in this group. Back then, the very idea of a semi-closed system that a bi-amplified loudspeaker like the ATC SCM19A represents would have been heretical to my high-end aspirations. But, as they say, that was then.

    I think I get to correct the decision. Don't despair.
