C20 Audiophile Top 25 of All Time AwardSound Image Award

Line Source In-Wall Loudspeaker

The C150i incorporates a 50-inch tall planar magnetic line source for mid and high frequencies, accompanied by two woofer arrays containing 16 proprietary high operating pressure woofers which is equivalent to a 15” woofer. The C150i (in-wall) and C150m (on-wall) Sage Series models feature the same line source planar magnetic technology found in the Sage Series L75 and L150 but measure a more compact 50 inches in height.

Architectural Design with Custom in Mind

Slim and elegant in design, the In-Wall Sage C150i slim grill can be painted to blend nicely into any 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.
