Atc scm 150

It was founded by Bill Woodman — who is also a pianist and studied engineering in Australia before moving to the UK. After immersing himself in the world of speaker design, Woodman felt he could do better and decided to design his own drivers. A few years later, the ground-breaking SM s soft dome midrange driver was born — and the rest was history. This is the core of their brand and products. These products include passive and active speakers for both the consumer and professional space. It is named after its small 7-liter enclosure.

With its third revision, the SCM7 v. Solid white is very elegant and looks great on my desk. The first thing I noticed when taking these speakers out of the box was its weight. This is used to improve rigidity and reduce internal resonances. Lastly, there is a pair of five-way binding posts for optional bi-wiring.

This type of enclosure design is used to dictate the movement of the speaker. This typically implies a smoother bass roll-off mates better with a subwooferbetter transient speed, lower distortion, and lower phase delay. Wonder how I generate such great content?

I have an obsession with the enjoyment of all things media - specifically in the realm of music and film. So much heart and soul and money go into the creation of this artistry.

My aim is to find out which products get me closer to what the musicians and directors intended.Forum Rules. Login Register.

Remember Me? Results 1 to 3 of 3. Trying for many years to have a list of my top five favorite loudspeakers regardless of price now has a very unexpected speaker to my list. They always tend to sound all over the place and dynamically inept no matter what amp you put on them.

All my favorite speakers have to be musically approachable - I want to listen to all my music and not be either bored or irritated with fatiguing treble. I can live with a little less accuracy when I am rewarded with the ever elusive "musicality" which is a pain to try and convey with words. The ATC SCM passive is likely to be the most accurate speaker in my top 5 list which also makes it somewhat aloof compared to some of my other top 5 speakers.

What the ATC does that every other Pro-Monitor speaker I have tried for extended periods is sound accurate without ripping the source discs apart so much that all you hear is disjointed presentation. The SCM has immense control through the entire frequency spectrum and there is just enough of that touch of warmth to make you want to keep listening.

Auditioning with 40 and 50 watt Tube amplifiers KT 88 and EL34 based integrated amps both easily drove the speaker to louder levels than I would normally use. KT88s tend to sound more solid State like so it sounds arguably thinner and more airy and open but less weighty and created that aloof sensation.

The El34 amp was less hyper detailed and richer with more of foundation in the bass - I think a higher end or based amp will meet somewhere in the middle giving the SS "grip" while maintaining integrity to the emotion sought by musicians. My recently purchased Line Magnetic tube CD player is at left.

The big long black Melody tube amps are beside the speakers - The 40 watt Line Magnetic amp had no trouble with the SCM but if you really like more gusto the Melody's are pure class A watt beasties.

The funny thing looking at the ATC is they remind me of the first pair of speakers I bought that were any good. And I still have them - the Wharfedale Vanguard based on the E Well remind me in terms of looks.

The Vanguard was completely different in most ways - mostly 10 ohms, horn tweeters and only a 10 inch woofer in a 70 litre cabinet hence E Attached Images. All times are GMT It is interesting to contrast the sound of the USB input with the network or server input; in most cases USB has a more 'hi-fi', but ultimately less engaging, and well timed sound, but here the network sound excels in both resolution and timing.

Obviously this result will vary with different sources, but I made it using the same source Melco N1A and could hear more via its direct Ethernet connection and found the timing more taut and clearcut. The use of space is fabulous — nearly as fabulous as the power of the synth bass, which is proper internal organ vibrating stuff. Even with less than 50cm to rear walls, and not a lot more to the sides, the bass is very tidy and controlled.

This speaker used to be a bit 'warts an' all' for anything less than smooth, clean electronics and recordings, but the tweeter has made the a whole lot more charming without losing transparency. The Primare is a very impressive piece of kit, too; this is where the fine detail in the sound is coming from and the fact that it can produce such a stunning result while combining so many functions is very impressive indeed.

Driver complement: One 25mm soft dome tweeter, one 75mm soft dome mid-bass driver, one mm doped paper bass driver.Audiophiles and active loudspeakers have had, shall we say, an uneasy relationship over the years. The squabble goes something like this: Active speakers defined here as speakers equipped with on-board amplifiers and electronic crossovers are the outsiders, creations of and for the recording studio—only pros need apply.

The argument continues that while active designs tout tonal accuracy, they are just as often described as amusical and clinical-sounding beasts geared to play all day and night at ear-splitting levels. However, time, tastes, and technology have narrowed, if not mended, the great divide between the passive and active camps.

Today, for example, there are countless hybrid models with powered bass transducers Vandersteen, MartinLogan, GoldenEar. The company has been in this game since its founding in Acoustic Transducer Company ATC for short actually began by concentrating its efforts on the design and in-house manufacture of custom transducers for the pro-sound market. By the end of that decade it had started producing professional active monitors, adding electronics and amp packs soon thereafter, and then, finally, consumer-oriented products.

The original SCM50A came into being as the result of a request by Danish Radio for a compact monitor speaker for its broadcast trucks. Subsequently adopted by recording studios, it has steadily evolved with the passage of time. The SCM50 ASLT is a three-way floorstander that tops out at around 40" in height and a foot in width, and thanks to its amp-packs extends rearward a full 18".

The look is that of a traditional British loudspeaker—boxy, understated, yet handsomely brutish. The midrange and tweeter drivers are vertically offset relative to the woofer, reducing the effects of cabinet diffraction and permitting the user to orient the speaker according to taste—drivers inboard tend to pinpoint images and add depth to the musical stage, while outboard adds a bit more width.

The baffle is 25mm thick. We use a thicker, heavier, more inert front baffle on many of our products because this panel faces the listener—panel resonances from this area are more audible. The baffle is secured with fourteen Allen-type bolts, the woofer alone uses eight more. Should you wish to disguise these details, the grille frame is cleverly designed to snuggle around the edges of the projecting front baffle for low diffraction. Standard finishes include satin cherry, oak, walnut, and black ash.

I found the overall fit and finish excellent—it speaks to solidity and permanence.

This is a tri-amplified loudspeaker that delivers W to the woofer, W to the midrange, and 50W to the tweeter. In operation, the amps are dead silent. The heart of every loudspeaker is its transducers. Each driver is a bespoke ATC unit, engineered and manufactured in its venerable factory in Stroud, England.

Per ATC practice it uses a short coil operating in a long magnetic gap aka, it is underhung. For one driver. The crossover is a fourth-order Linkwitz-Riley type, with hinge points at Hz and 3.

Admittedly I felt an instant familiarity with these speakers. A pianist himself, Woodman and his team use the sound of a piano to weigh every ATC design.You are reading the older HTML site. Speaker cables are either Ixos or Belden A. BDR cones.

ATC SCM-150SL

I've written and rewritten this review, but still feel that I've failed to capture my experience with ATC's simple but satisfying SIA integrated amplifier.

Products that are immediately and obviously impressive are easier to write about, and products that suck are easy, too. I won't say that this is the most transparent amplifier I've heard, nor is it without character, but it tickled my fancy without letting me know how and where I'd been tickled. After listening to the SIA for about four months, I found that it had gotten under my skin in a subtle, welcome, and satisfying way. This is a self-effacing amplifier, sort of like its name.

This says gobs about ATC. The simple nomenclature mirrors the amp's performance.

It allows you to listen and listen to music without calling attention to itself. The only aspect of the design that might seem the slightest bit tweaky, for ATC at least, is that there are no phase-distorting integrated circuits. Also, ATC employs a protection design called a Momentary Gain Reduction circuit, which prevents damage to speaker drivers if the amplifier is overdriven.

This probably explains why the amplifier behaved itself with everything I threw at it. I was not nice to the amplifier or my speakers in testing it out. One of the great things about ATC gear is that it's built like a brick mailbox. These products are designed to last and last, take whatever you give them, and sound good doing it. The SIA always sounded rich, and I prefer a richer sound. Above all things, I listen for a natural tonal balance.

I don't care about imaging, bass, or the rest until I hear a realistic rendering of timbre. If the tone of a violin or piano or guitar or human voice is off, there's no point for me to continue listening. You'll be hard pressed to get a screechy sound from an ATC product.

I like their ability to produce realistic timbre while still delivering detail.That's arguably always been the way with ATC speakers, which bear their studio heritage as a badge of honour and make few concessions to domestic acceptability. However, these speakers are also available in a range of alternative wood finishes, and you can select different colours for the 'brow' and 'horns' — the front edge of the top panel and the little trim pieces at either end of that edge.

Nevertheless, the polished black-and-gilt chosen for our review pair gave them a decidedly formidable appearance, and did little to camouflage their extravagant dimensions. Mind you, given their glitz, one is drawn to the conclusion that this finish is one likely to be chosen by users wanting to draw attention to the conspicuous investment in their system — subtle it isn't!

Relative Bargain Given that the onboard active crossover and three-channel amplification, derived from the company's Anniversary models, account for only a relatively modest 5kg of that mass, it's not hard to see how substantially built the rest of the speaker is. But then that's another of those ATC hallmarks.

That seems like something of a bargain, if you can use the term at this kind of price-level. Signature Feature That's before you get into the whole discussion about the merits of active filtering, and with each drive unit being powered by an amp optimised for its task. Remove the flush-fitting grilles and they are revealed, standing proud of the main cabinet in their own matt black baffle. The look is very much a functional one, accentuated by the gap between 'brow' and baffle — the speaker looks more 'of a piece' with its grille in place, but then you lose that studio aesthetic.

The drivers themselves look familiar from past ATC designs, with the 7. Here it's partnered with an all-new 25mm soft dome tweeter and a 30cm bass unit, the ensemble being mounted in a litre cabinet — hence the model number.

I wouldn't say it makes the SCMSE look small — not much would — but while the 'midrange' speaker here hardly merits the title, there is more in the range should you feel you need it. Rolling in at 3. This is designed to ensure pistonic motion just as ATC's narrowing of the magnetic gap is aimed at reducing distortion. The 'motor' is built with oversized, hugely powerful neodymium magnets, extending the frequency response as well as dissipating heat from the driver assembly. This has allowed the tweeter to be built without the ferrofluid often used for cooling in such units.

This plays its part in ATC's quest for durability, the company saying it has thus avoided the loss of performance caused by the drying out of such fluid over time. The dome itself is designed to optimise power transfer from the motor, while the waveguide for the tweeter is machined from alloy for rigidity and resonance control, and acts to optimise dispersion and on-axis response.

Sticking To Paper The 7. This keeps the coil in the magnetic gap throughout its excursion, unifying as much as possible the motive force and coil inductance. According to ATC, audible issues caused by variations in inductance with current are held in check, just as the woven dome is sealed by its coating and has a very high internal damping to help quell any resonances.

Finally the dual suspension arrangement, using two small roll-surrounds, gives more accurate control of the motion of the dome and coil.The SCM As are massively talented.

Rarely if ever has deep bass sounded so good, so loud, or so nuanced. Speakers like the SCM A move goal posts. In active form, with W of power amplification built-in, they deliver massive volume with awe-inspiring composure.

Most conventional passive alternatives would crumble if asked to deliver a similar volume of sound. How loud? So clean do these floorstanders sound that we found ourselves listening to them far more loudly than usual. It was only when we had to shout to be heard that we realised how high the volume really was. After all, this is an active three-way design with a massive litre cabinet and a 31cm bass driver.

The chances are it would be able to do those things — with all the gusto we could hope for. That large bass driver dovetails beautifully into the midrange, and manages to deliver lots of bass without attracting too much attention.

These floorstanders are immensely muscular when required, but with subtler music such as this, their agility and finesse is deeply impressive. Hugely demanding to own In some ways this is a hugely demanding speaker to own. Any shortcomings in either area will be highlighted.

A weight of 68kg per enclosure means moving them around is awkward and many will have an issue with their rather functional appearance. Yet, considering the level of performance on offer — and the inclusion of dedicated power amplification for each driver - makes the SCM As stonking value.
