In 1974, in England, Australian Reverse-Pommy pianist and recording engineer Billy Woodman founded the Acoustic Transducer Co. (ATC) as a maker of loudspeaker drive-units. That makes ATC a few years younger than Spendor (1969) and a few years older than Harbeth (1977). When I mentioned all that to a quick-witted audio buddy, he immediately came back with "Middle Child Syndrome!"
It does seem that ATC has gotten less attention in the US than its older and younger British siblings. In an effort to rectify that, ATC is updating their loudspeaker designs and changing their US distribution arrangements.

ATC developed the first soft-dome midrange driver, and pioneered self-contained active (ie, powered) speakers. The company remains independently owned, and their products—which include preamplifiers, power and integrated amplifiers, a CD player–DAC, and a new CD receiver with USB input—are made in England. Celebrity owners of ATC speakers include T Bone Burnett, Coldplay, Enya, Diana Krall, Lenny Kravitz, Ziggy Marley, Tom Petty, Pink Floyd, the late Lou Reed, the Rolling Stones, Paul Reed Smith, Sting, and Roger Waters. The last pair of loudspeakers Stereophile founder J. Gordon Holt purchased were ATCs.

ATC offers both Professional and Consumer lines of speakers, the latter in wood veneers and, usually, in both passive and active versions. The four models in their Consumer Entry Series, including the entry-level Entry SCM7, are passive only. All of ATC's Professional speakers are active, with some also available in passive form. With two exceptions, the pro models are offered in a finish of semigloss black paint.

In many instances, ATC constructs pretty much identical speaker designs for both markets. One such pair of twins is the SCM50, with ATC's 1" soft-dome tweeter, 3" dome midrange, and 9" woofer. The Consumer SCM50 is available (as active or passive) in a choice of Black Ash, Cherry, Maple, Oak, Pippy Oak, Rosewood, and Walnut, or (by special order) in a veneer of any legally available hardwood. The Professional SCM50 is available (as active or passive) in black paint, and has a blanked-off cutout on the front panel to enable relocation of the tweeter above the midrange driver if the cabinet is to be positioned horizontally rather than vertically. The passive pro model uses a Speakon connector for its amplifier input.

However, such design twinship is not always the case. The entry-level SCM16A Pro and SCM20ASL Pro active monitors (both about to be replaced, though old stock may still be available) have distinctive aluminum cabinets with curved sidewalls and radiused front panels and edges, built-in front-panel tilt-back, and no grilles. Those two aluminum cabinets are unique to the Pro line. There are also Pro models with double woofers that lack exact Consumer twins, in that the Pro versions are stand-mounted while the Consumer versions are towers.

One Consumer speaker appears to be in a class of its own. The EL150 is ATC's "statement" model, at $47,770/pair passive and $84,999/pair active, in the standard veneer of burr magnolia. Its very wide and shallow cabinet is reminiscent of Sonus Faber's Stradivari or Elipsa. (An ATC speaker's model number indicates its internal volume, in liters; eg, the SCM19 has a volume of 19 liters.)

Perhaps one reason ATC's profile in the US has always been lower than Harbeth's or Spendor's is because US audiophiles historically have resisted the idea of active speakers. Although powered speakers offer advantages in implementing crossover slopes and in amplifier efficiency, over the years, I've been told many times that US audiophiles absolutely insist on choosing their own power amplifiers and speaker cables.

I wonder whether that conventional wisdom might be crumbling. What makes me think that US audiophiles might be getting ready to seriously consider ambitious active speakers is the market success of such models as Audioengine's 5+ ($399/pair). I don't think that all of Audioengine's customers are using their 5+s on desktops with computers; I suspect that many use them as the main speakers of a stereo system. Time will tell.

I wrote about ATC's SCM11, a two-way stand-mounted speaker, in December 2009 and about the SCM40, a three-way tower with ATC's famous dome midrange, in April 2010. John Atkinson concluded his measurement report on the SCM11 with this: "The ATC SCM11 is a well-engineered little speaker. I am not surprised John Marks liked it as much as he did, though I would point out that its measured behavior suggests it will work better when listened to fairly close."

I'd been lent the SCM11 and SCM40 by ATC's then importer and distributor for its Consumer models, Flat Earth Audio, of Connecticut. In mid-2013, ATC decided to consolidate its US presence by reassigning the responsibility for consumer speakers to Transaudio Group, which had represented ATC's professional products in the US for many years. To emphasize its expansion into the consumer market, Transaudio has established a subsidiary, Lone Mountain Audio. At present, Lone Mountain Audio represents only ATC.

Because I was revisiting the broader subject of professional equipment that audiophiles should know about (such as the Lindell AMPX class-A power amplifier I wrote about last December), or at least consumer equipment with professional roots, I requested the loan of ATC's Consumer SCM19, the next size up from the SCM11. The SCM19 is also ATC's least-expensive loudspeaker whose woofer incorporates their Super Linear magnet technology. I was then told that ATC was updating all its models, starting with the smallest, the SCM7, and that the updated SCM19 would not be available for several months.

I agreed to review the SCM7 because I was curious what ATC's updated entry (this is v.3) in the evergreen British Shoebox Monitor sweepstakes would sound like—that despite Lone Mountain Audio's Brad Lunde hastening to point out that the SCM7 contains no more BBC LS3/5A DNA than any other British-made shoebox-sized two-way. ATC's design goals for the SCM7 are to offer a minimonitor with excellent dynamics and best-in-class bass. For the first time, the tweeter has been designed and built in-house by ATC.

The SCM7 v.3
The cabinet of the previous-generation SCM7 had square corners and flat sides—definitely a 1980s–90s look. Its drivers were mounted on a black-painted baffle board with radiused edges and grille-attachment grommets. This board covered most of the front panel, the rest of which was veneered.

Điều đó làm cho ATC một vài năm trẻ hơn Spendor (1969) và một vài năm cũ hơn Harbeth (1977). Khi tôi nói đến tất cả những gì để một quick-witted âm thanh buddy, ông ngay lập tức trở lại với "Hội chứng trẻ em Trung!"Nó có vẻ rằng ATC đã nhận được ít sự chú ý ở Mỹ hơn của nó lớn và anh chị em người Anh em. Trong một nỗ lực để khắc phục đó, ATC Cập Nhật thiết kế loa của họ và thay đổi của sự sắp xếp phân phối Hoa Kỳ.ATC phát triển trình điều khiển các mái vòm mềm đầu tiên, và đi tiên phong trong khép hoạt động (tức là, được tài trợ) loa. Công ty vẫn còn sở hữu một cách độc lập, và sản phẩm của họ-đó bao gồm preamplifiers, quyền lực và bộ khuếch đại tích hợp, một máy nghe nhạc CD-DAC, và một bộ tiếp nhận đĩa CD mới với đầu vào USB — được thực hiện tại Anh. Người nổi tiếng chủ sở hữu của ATC loa bao gồm T xương Burnett, Coldplay, Enya, Diana Krall, Lenny Kravitz, Ziggy Marley, Tom Petty, Pink Floyd, Lou Reed cuối, Rolling Stones, Paul Reed Smith, Sting và Roger Waters. Các cặp cuối của người sáng lập Stereophile của loa phóng thanh, J. Gordon Holt mua là ATCs.ATC cung cấp chuyên nghiệp và người tiêu dùng dòng loa, sau này trong gỗ gỗ, và thông thường, trong các phiên bản thụ động và hoạt động. Bốn mô hình trong tiêu dùng mục loạt của họ, trong đó có SCM7 mục nhập cấp, duy nhất là thụ động. Tất cả của ATC chuyên nghiệp loa đang hoạt động, với một số cũng có sẵn trong hình thức thụ động. Với hai trường hợp ngoại lệ, các mô hình chuyên nghiệp được cung cấp tại một kết thúc của sơn màu đen semigloss.Ở nhiều khía cạnh, ATC xây dựng khá nhiều thiết kế loa giống nhau cho cả hai thị trường. Một như vậy cặp sinh đôi là SCM50, với ATC của 1" mái vòm mềm tweeter, 3" mái vòm tầm trung, và 9" woofer. SCM50 người tiêu dùng có sẵn (như là đang hoạt động hoặc bị động) trong một sự lựa chọn của đen Ash, Cherry, Maple, sồi, Pippy Oak, Rosewood, và Walnut, hoặc (theo thứ tự đặc biệt) trong một veneer bất hợp pháp có sẵn bằng gỗ cứng. SCM50 chuyên nghiệp có sẵn (như là đang hoạt động hoặc bị động) ở sơn màu đen, và có một video ra bỏ đi trên mặt trước để cho phép di chuyển của tweeter trên các trình điều khiển nếu nội các là để được bố trí theo chiều ngang hơn là theo chiều dọc. Thụ động mô hình chuyên nghiệp sử dụng một kết nối Speakon cho nó khuếch đại đầu vào.Tuy nhiên, như vậy twinship thiết kế không phải là luôn luôn là trường hợp. Các mục nhập cấp SCM16A Pro và SCM20ASL Pro hoạt động màn hình (cả hai là về để được thay thế, mặc dù chứng khoán cũ vẫn có thể có sẵn) có đặc biệt nhôm tủ với cong sidewalls và radiused trước tấm và cạnh, được xây dựng trong bảng điều khiển phía trước nghiêng-trở lại, và không có thùng rác bằng gang. Những hai nhôm tủ được duy nhất cho dòng Pro. Có cũng rất Pro mô hình với đôi woofers thiếu chính xác các em sinh đôi người tiêu dùng, trong đó các phiên bản Pro được đứng-gắn kết trong khi các phiên bản của người tiêu dùng có tháp.One Consumer speaker appears to be in a class of its own.
