Four unobtrusive satellite speakers complete the SMS1 system. Each speaker measures just 5-1/4" x 3-1/2" x 3-1/2". These tiny speakers can be located at strategic locations within the business to either minimize or augment the visual impact.

The SMS1-Sat speaker is installed easily using JBL's patented Invisiball mounting system, which allows for a wide range of adjustment in a unique theft-resistant design.
