Sonance Symphony Single Stereo Technology
®
SST and SSTR speakers are ideal for use in hallways, bathrooms , closets, or in any location where listeners will
be moving around and a pair of stereo speakers would be impractical. Because a single Symphony SST/SSTR speaker reproduces both stereo channels from
a single location, it will deliver outstanding performance from an extremely wide variety of mounting locations. Your local authorized Sonance dealer is an
expert in audio/video system planning and installation. We strongly recommend that you work with your dealer to ensure that your system is properly
planned, assembled and installed.
Sonance Symphony SST/SSTR-series speaker models have very smooth and predictable off-axis response, so they provide excellent coverage in distributed audio
systems from a wide variety of installation locations. The char t in
Figure 1
shows how far apar t the speakers can be placed at different ceiling heights while
still providing good coverage (as shown in
Figure 2
). The distances are based on ear heights of 62” for standing listeners and 40” for seated listeners.
