S110i fc subwoofer


In-Wall RTL Subwoofer

The S110i follows closely in the footsteps of our flagship model STS, widely recognized as a benchmark in subwoofer performance. In installations where the STS is impractical due to its large size, the S110’s compact form factor neatly accommodates a wide range of installation options. The subwoofer can be positioned within a screen wall and secured with its integrated mounting flange; vented into the room with a flexible port kit from an adjacent space, basement, or attic. The S110i has an incredible maximum SLP of 128dB at 30Hz.

The Regenerative Transmission Line®

Regenerative Transmission Line® designs yielded the unique combination of high sensitivity, high output, and low distortion with the uniform and extended response we required. The result is extraordinary power and punch combined with a remarkable level of quickness, tunefulness, and realism.
