ATC SCM12i Pro Compact 2-Way Passive Install Monitor - Pair

Compact 2-way passive monitor designed for installation into recording, post-production, broadcast and film studios.

Product Description

The ATC SCM12i Pro Install Monitor is a compact 2-way passive monitor designed for installation into recording, post production, broadcast and film studios. It’s compact size and exceptional performance make it an ideal loudspeaker for use in surround/multi-channel recording/mixing and immersive audio applications such as Dolby Atmos, DTS:X and Auro 3D.

The SMSC12i Pro Install is a passive two-way studio monitor designed for installation into recording, post-production, broadcast and film studios. Equipped with a state-of-the-art CLD mid/bass driver and a dual-suspension tweeter, SMSC12 Pro monitors deliver outstanding clarity and class-leading dynamic range. With pristine sound and a compact footprint, SMSC12 Pro monitors are ideal for surround sound mixing and immersive audio applications such as Dolby Atmos, DTS:X and Auro 3D.


The SCM12i Pro Install is fitted with four M8 mounting points in the rear face for quick and easy permanent installation. Compatible with widely-available multi-mount pan and tilt mounting brackets, SCM12i can be safely and securely mounted to the ceiling and walls for advanced surround sound setups.


The ATC SMSC12i Pro Install features a 1-inch soft dome tweeter with an innovative dual-suspension design for silky smooth highs up to 22 kHz. Unlike conventional tweeters, ATC’s dual-suspension tweeters offer far greater control of the voice coil and dome motion, especially at higher sound pressure levels. By reducing internal distortion, this groundbreaking design delivers an extended high-frequency response with improved clarity and definition. ATC’s dual-suspension tweeters also significantly reduce listener fatigue, allowing you to work on long mixing projects without losing perspective.


SMSC12i Pro Install studio monitors are equipped with ATC’s legendary 6-inch Constrained Layer Damping (CLD) mid/bass driver. With a 1.75-inch diameter voice coil, and a Finite Element Analysis (FEA) optimized high-energy symmetric gap motor system, CLD drivers deliver an extended dynamic range for powerful, distortion-free low-end even at high SPLs. ATC’s Constrained Layer Damping technology uses multiple laminated fabric cones to form a stiff, light, driver cone for smoother on- and off-axis frequency response and minimal distortion.


SMSC12i Pro Install studio monitors feature a high-performance passive crossover with 250 VDC metalized polypropylene capacitors and hand-wound air-cored type inductors for minimal signal loss and distortion. While SMSC12i Pro Install studio monitors are designed to work with any traditional power amp, they perform best when paired with ATC’s 150 W per-channel P1 Pro dual-mono power amplifier. With class-leading power output and outstanding sonic resolution, ATC power amps deliver unparalleled performance.

I absolutely love my ATC speakers! I have a 7.1.4 setup with 3 ATC SCM25’s and 8 scm12i pro’s. The listening field is amazingly transparent, like you don’t feel like the sound is coming from speakers. The accuracy and detail of what I hear while working really enables me to make quick and accurate decisions. VK was incredibly helpful getting me going.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
