Line Source In-Wall Loudspeaker

It combines our state-of-the-art planar transducer elements in a way that takes full advantage of their inherent performance benefits. It offers a no-compromise solution for customers that require a high-end audiophile loudspeaker that fully integrates into their home.

Architectural Design with Custom in Mind

Slim and elegant in design, the In-Wall Sage L150i slim grill can be painted to blend nicely into your décor, or select the ultimate Custom Size Grill to match any design element.

Eliminate Floor and Ceiling Reflection

The Line Source design eliminates floor and ceiling reflection while distributing sound levels uniformly across the width of any room.

Big Bass in Small Boxes

Featuring Sage Series dynamic woofers that are more than twice as powerful as typical woofers for great bass without huge, ugly boxes that are difficult to place.

Power Over Distance

Line Source provides a much better power constituency than a point source. This is a great benefit when designing an entertainment system in large modern open-floor living spaces as well as multi-tier theaters.
