ATC Loudspeakers SCM150A Pro 3-Way Active Monitor - Pair

Product Description

The ATC Loudspeakers SCM150A Pro is a large-format active studio monitor built to deliver reference-grade sound for critical mixing, mastering, and post-production applications. Pairing ATC's Super Linear bass driver, Super Dome mid driver, and dual-suspension soft dome tweeter with a powerful 350 W amplifier, active crossovers, LF contour control, input sensitivity trim, and clip indication, the SCM150A Pro delivers the brand's signature sound in a package that's perfect for mid- and large-sized studios. Read on to find out why the ATC SCM150A Pro belongs in your control room and talk to a Vintage King Audio Consultant about upgrading to a pair of these studio monitors today.

SIGNATURE ATC SOUND

ATC Loudspeakers have been around since 1974, and the ATC SCM150A Pro is a direct result of that legacy. Thanks to decades of research and development in speaker, amplifier, and crossover design, each pair of these professional active monitors delivers a clear and neutral frequency response that reveals every detail of your music. Hand-wound voice coils, precision magnetic gaps, and vented magnet assemblies ensure minimal distortion, while soft dome radiators deliver the natural midrange that engineers trust for critical listening. With a pair of ATC studio monitors, you can trust your music to translate reliably to everything from consumer speakers to cinema sound systems, which is why ATC monitors are a mainstay of mastering rooms worldwide.

SOFT DOME TWEETER

The ATC SCM150A Pro features a 25 mm dual-suspension S-Spec soft dome high-frequency driver designed and built entirely in-house by ATC. The dual-suspension design keeps the dome on axis as it travels, suppressing resonant modes and the distortion they cause, while the neodymium motor system supports fast transient response above the 3.5 kHz crossover point. The high-end extends all the way up to 22 kHz , so cymbals, ambience, and reverb tails stay crystal-clear instead of blurry or harsh.

SUPER DOME MID DRIVER

The 75 mm Super Dome mid driver covers 380 Hz to 3.5 kHz in a single band, covering the critical midrange frequencies. Larger than a conventional dome yet far smaller than a midrange cone, this ATC design keeps the midrange open and uncolored, even at high monitoring levels. A hand-wound flat-wire voice coil operating in a long, precise magnetic gap keeps distortion far below what typical mid drivers produce. On the ATC SCM150A Pro, that clarity turns vocal balance, dialogue intelligibility, and dense arrangement decisions into obvious calls rather than guesswork.

SUPER LINEAR BASS DRIVER

The ATC SCM150A Pro replaces the 300 mm driver of the SCM100ASL Pro with a full SL spec 15˝/375 mm unit in a 150-liter cabinet. The result is extended bass, greater headroom, and more dynamic range than most other bass drivers can deliver. Super Linear technology adds a specially formulated material to the magnet assembly, cancelling the distortion that colors lesser bass drivers. Low-frequency output reaches all the way down to 25 Hz, and the rear panel LF EQ adds as much as 6 dB at 40 Hz to compensate for free-standing placement or a large room.

THREE-WAY, TRI-AMPLIFIED DESIGN

The onboard 350 W grounded source Tri-Amp Pack pushes 200 W to the woofer, 100 W to the midrange driver, and 50 W to the tweeter, matching each amplifier to its driver via active crossovers at 380 Hz and 3.5 kHz. Because filtering happens before amplification, this three-way approach reduces phase smear and power loss, and keeps the pair coherent across the frequency range. Rear-panel input sensitivity trim and LF contour control match these active studio monitors to your room.
