Indoor and Outdoor Applications

The LB20 series of Premium commercial loudspeakers for indoor and outdoor applications offers easy installation and exceptional Bosch audio performance in an incredibly versatile format.

Compact and Cost-Effective

All models offer Bosch-engineered components for superior sound quality, low-profile looks and robust reliability for a wide range of indoor and outdoor applications.

New Wall-Mount System

The innovative, new wall-mount system makes installation literally "as easy as 1-2-3" - quicker and easier than ever before. Attach the wall-mount (a built-in bubble level saves time) and terminate the cables inside, then apply the paint cover to protect the wall-mount. Finally, simply slide the pre-wired speaker with an adjustable arm onto the wall-mount and lock it into place.
