Description
The ATC SSM25i Pro is a mid-sized, high-performance passive 3-way loudspeaker that delivers exceptional audio quality through a combination of advanced engineering and premium components. It based on the legendary SCM25A Pro MK2. The speaker can be wall or ceiling mounted in vertical or horizontal orientations. In addition, the mounting hardware allows the cabinet to pivot away from the wall/ceiling surface, directing more of the output towards the listening position resulting in a superior balance and precise imaging.
The SSM series of passive loudspeakers is engineered to provide accurate, consistent monitoring when mounted on control room walls or ceilings. Featuring shallow cabinets and a versatile mounting bracket solution, these loudspeakers offer flexible installation options. They are an ideal choice for multichannel and immersive audio setups – including Dolby Atmos systems – in control rooms where space is at a premium, but reference-level performance is essential.
Reasons to choose the ATC SSM25i Pro:
- Sound character derived from the legendary ATC SCM25A Pro MK2, offering the same level of precision and transparency.
- Slim, shallow-depth design for easy integration into walls or ceilings.
- Adjustable mounting that allows the loudspeaker to be aimed directly at the listening position.
- Ideal for control rooms with limited space.
- Three-way system featuring powerful, well-controlled bass, an exceptionally natural and detailed midrange, and accurate high frequencies.
- Optimised for Dolby Atmos and immersive surround sound systems.
