ATC SCM16A MONITORS
November 2007—This new console-top monitor from ATC (dist. by LasVegasProAudio, www.lasvegasproaudio.com) boasts improved off-axis frequency response through the use of Constrained Layer Damping (CLD) on the bass driver. The innovation uses two lightweight driver cones that sandwich a constrained damping layer. When the cone flexes, CLD shears adjacent cone sections, causing unwanted vibration energy to dissipate as frictional heat rather than acoustic distortion. In addition to the 6-inch CLD mid/bass driver, the SCM16A ($3,995/pair) has a 1-inch, neodymium, soft-dome tweeter, upgraded onboard (200- and 50-watt) bi-amplification, and user-adjustable input sensitivity and bass boost.

ATC SCM20SL
October 2006—The new ATC passive SCM20SL ($3,500 per pair) loudspeakers feature the same woofer and tweeter as the active SCM20ASL. The SCM20SL passives are housed in a conventional "pro-black" box for easy placement on any meter bridge. ATC recommends amplifiers with at least 200 watts per channel of power. The SCM20SL passive low-frequency section is a hybrid design incorporating a 150mm bass cone with a grafted 75mm soft-dome for midrange-assist. The woofer magnet assembly uses ATC's "SL" technology to greatly reduce third-harmonic distortion and reveal mistakes and details. All ATC drivers are manufactured in-house.

ATC SCM20ASL PRO
July 2004—Distributed by Transamerica Audio Group, ATC's SCM20ASL Pro 5.1 package ($22,900) includes five active SCM20ASL Pro monitors with an active ATC Sub 1/15 Pro subwoofer. Combining two decades of innovative speaker design with the latest advances in materials technology, the ATC system is a unique, ultrahigh-quality surround system that just so happens to be extremely portable. The three-way SCM20ASL Pro monitor employs ATC's Super Linear magnet structure in its 6-inch mid/bass drive unit and is coupled with a 1-inch tweeter. The SCM20ASL Pro's active two-way amplifier design incorporates separate dual amp blocks in each cabinet and can deliver continuous SPLs of up to 108 dB measured at one meter. At the monitor's rear, a selector panel provides five LF boost settings and a flat reference setting. The ATC Sub 1/15 Pro subwoofer offers a custom-built 15-inch woofer driven by a massive, built-in 1,000W amp. The sub's versatile interface provides simplified setup with phase, level, lowpass and contour controls.

ATC SCMO
March 1999¸—Unveiled at AES, the SCM0.1/15 High-Power Sub Bass from ATC is designed specifically for surround applications, with internal 1,000-watt amplification said to produce SPLs to 124 dB with response down to 18 Hz (-6 dB) from a 2x2-foot cube. Onboard signal processing provides for easy setup with phase, level, lowpass and contour controls. Lowpass frequencies are adjustable to include the recommended 150 Hz for Dolby AC3. An optional multichannel control unit allows routing any of the five main channels into the sub, with full gain and phase control, for low-frequency support on any or all of the monitor channels. The SCM0.1/15 can be combined with any ATC monitors, but for most applications, the company's mid-sized SCM-20A PRO is recommended.
