ATC SSM25i Pro | High-Performance 3-Way Studio Surface Monitor

The ATC SSM25i Pro is a mid-sized, high-performance passive 3-way loudspeaker engineered to deliver reference-level audio in larger control rooms. By combining ATC’s world-renowned tri-axial driver technology with a specialized shallow-profile cabinet, the SSM25i Pro provides an uncompromising monitoring solution for Dolby Atmos™ overheads, surround arrays, and high-output immersive audio systems.

Reference-Grade Performance, Surface-Mounted

The SSM25i Pro is built for studios where floor space is a premium but “small” sound is not an option. It features a unique 3-way design that provides exceptional mid-range clarity and increased dynamic range, making it the ideal choice for primary surround or height channels in professional cinema and music production suites.

Key Performance Features:

• Advanced 3-Way Design: Incorporates the legendary ATC SM75-150 Soft Dome Mid-Driver, providing unparalleled vocal clarity and instrumental detail.

• Extended Low Frequency: Equipped with the ATC SB50-164SC Bass Driver, offering the punch and bandwidth required for modern, full-range immersive mixes.

• Shallow Enclosure: At only 198mm (7 13/16”) deep, this monitor sits tight against surfaces while delivering the acoustic scale of a much larger cabinet.

• Precision Aiming: The specialized articulating mounting hardware allows the cabinet to pivot, ensuring the acoustic center is perfectly aligned with the engineer’s sweet spot.

• Sealed Cabinet Accuracy: Optimized for boundary placement, the sealed design ensures a flat, predictable low-end response when mounted against walls or ceilings.

Technical Specifications

Seamless Integration for Immersive Audio

The SSM series is designed for consistency. The SSM25i Pro shares the same sonic DNA as the SSM12i Pro, allowing you to mix and match monitors within an immersive array (such as using 25s for the base layer and 12s for heights) while maintaining a perfectly coherent soundstage.

Important Safety Note: Because of the increased weight and size of the 3-way system, installation must be completed by a qualified professional using the integrated steel-reinforced mounting points.
