Specification Sheet

IS4 SST
The IS4 SST features single stereo technology, the ability to drive one speaker with two inputs.
The IS4 SST is impedance matched to ensure proper amplifier protection. The perfect choice for small
areas, such as hallways and corridors where two speakers would be impractical or impossible to install.
