WHY IT EXISTS
A line source hidden inside the wall.
Statement 40XW is one of the most extreme architectural loudspeakers in the category. Its 52-inch stack of thin-film tweeters and 40-driver total architecture are designed to create a high-efficiency line source without occupying floor space.
The installation is not a normal in-wall job: the product requires dedicated structural planning and its own installation kit.
SYSTEM ROLE
Where it fits in a cinema.
Large listening areas
Line-source behaviour is intended to maintain dynamic scale across large spaces.
Architectural statement
The loudspeaker disappears visually despite its physical scale.
ROOM DESIGN
Choose the room conditions before choosing the quantity.
FramingThe wall should be engineered around the speaker, not modified casually on site.
Screen positionBehind-screen use requires early coordination of screen-wall depth and speaker height.
AmplificationA high-performance line source deserves amplifier headroom and careful channel matching.
