Speaker Placement

Distributed Audio (SM55 and SM55 SST)
The SM55 and SM55 SST's low installation profile makes them
ideal for use in distributed audio systems. They provide coverage
of a very wide listener area, allowing them to be mounted in a
wide variety of installation locations.
Because a single SM55 SST speaker reproduces both stereo
channels from a single location, it will deliver outstanding
performance from a wide variety of mounting locations where a
pair of stereo speakers would be impractical, including hallways,
bathrooms and closets.
The table and illustration below show how far apart the speakers
can be placed at various ceiling heights while still providing good
coverage for all listeners.
