ATC SSM12i Pro (Pair)

The ATC SSM12i Pro is a compact, wall‑or‑ceiling‑mountable passive two‑way studio monitor that packs a shallow 147 mm cabinet, an ATC SB45‑150CLD mid‑bass driver, an ATC SH25‑76 dual‑suspension tweeter, sealed‑cabinet low‑frequency consistency and a six‑year warranty – all optimised for accurate, immersive monitoring in space‑constrained control rooms.

Key Specifications

The unit features a 147 mm deep cabinet that fits tight installations. ATC’s SB45‑150CLD mid‑bass driver delivers tight, controlled bass thanks to constrained‑layer damping, while the SH25‑76 dual‑suspension tweeter provides crisp, detailed highs. A steel‑reinforced enclosure protects the drivers, and a safety tether ensures reliable mounting. Articulating hardware lets the speaker toe‑angle toward the listening position, improving imaging and balance. The sealed cabinet maintains consistent low‑frequency performance when surface‑mounted, and the six‑year warranty guarantees long‑term reliability.

Mounting Flexibility

The articulating mounting system permits vertical or horizontal placement on walls or ceilings. Users can pivot the cabinet away from the surface, directing sound toward the listening spot for superior balance. Installation requires a qualified professional, ensuring safe, secure fitting.
