Advanced processing further enhances the bass response. Both woofers face inward to create a force-canceling effect that neutralizes distortion. Trueplay™ tuning technology adapts the bass for the unique acoustics of the room so it never sounds harsh, muddy, or flat—even if you place Sub Mini next to the wall. Elegant and compact, Sub Mini blends in beside your furniture and easily fits under a desk or table. Sub Mini connects to your system over WiFi, so you can place it wherever it fits and looks best in the room. Just plug in the power cable, open the app, and follow a few simple instructions to add Sub Mini to your system. The volume automatically adjusts along with your paired soundbar or speaker. Use the Sonos app to customize the EQ and change the bass level to your preference.
