Sonance Symphony SSTR
®
speakers feature
Single-Stereo Technology
®
that combines the
outputs of your amplifier’s left and right stereo
channels to play both signals from just one
speaker. The Single-Stereo Technology line now
includes a rectangular model (S623
SST) that
expands installation opportunities.
Symphony SST/SSTR speakers are ideal for use
in hallways, bathrooms, closets, or any location
where a pair of stereo speakers would be
impractical. Their innovative fully-pivoting
design delivers outstanding musical performance
from a wide variety of challenging installation
locations.
The SRS1 is designed to create a diffuse,
enveloping soundfield that is ideal for home
theater surround channel applications.
Features:
• SSTR/SST models feature Single Stereo
Technology
®
— reproducing left & right stereo
channels from a single speaker — ideal for
use in areas where space is limited.
• Round (-SSTR) and rectangular (-SST) foot-
prints provide installation flexibility to
compliment a wide variety of décor.
• Fully-pivoting woofers (SSTR/SRS1) direct the
sound at listeners for clear sound even when
speaker placement options are limited.
• A 3-position tweeter adjustment switch lets
you balance the speaker’s high-frequency
energy to better compliment your room’s
setup and acoustics (S623
SSTR).
• SRS1 creates a diffuse, enveloping soundfield
that is ideal for home theater surround
channel use.
• The RotoLock
®
mounting system makes instal-
lation quick and easy.
• Exclusive new FastMount
®
tabs hold speaker
in the mounting hole during installation,
allowing installer to let go of the speaker to
pick-up tools or other items.
