on-ceiling
design
is
ideal
for
installations that cannot accommodate flush-mount
in-ceiling speakers.
• Extremely simple installation: Connect the mount-
ing plate to speaker wire and screw the mounting
plate to the J-box. The speaker attaches to the
mounting plate via powerful neodymium magnets.
• The rotating mounting plate allows the SM55 to
be aligned with lighting fixtures or other decor
features after installation.
• A new coaxial woofer/tweeter produces smoother
frequency response, improves stereo imaging and
reduces tonal variations caused by less-than-ideal
placement.
• The dome-shaped speaker baffle surface ensures a
wide coverage area.
• The dense polypropylene enclosure absorbs
vibrations, for uncolored sound.
• The perforated aluminum grille and its ABS plastic
frame are paintable in one easy step to match the
decor.
The new Sonance SM55 surface-mount speaker is the
perfect solution for those who demand quality sound but
cannot use flush-mount in-ceiling speakers. In the SM55,
Sonance engineers have created a speaker that sounds
great, yet is decor-friendly, very easy to install and
doesn’t require a mounting hole.
The clever mounting system allows the SM55 to be
installed in a matter of minutes, using only a screwdriver. A
mounting plate receives the speaker connections from the
amplifier, and then attaches to a standard in-ceiling J-box
via two screws. As the installer places the SM55’s bottom
surface against the mounting plate, six powerful neodymium
magnets on the SM55’s bottom surface securely attaches it
to the mounting plate — that’s all there is to it. Once
installed, the installer can rotate the speaker to align it
with other features of the room’s decor.
A new coaxial woofer/tweeter driver featuring a 5¼”
carbon fiber cone woofer and a 1” silk dome tweeter
guarantees high-quality reproduction of music and voices.
The driver’s coaxial design reduces tonal colorations and
improves stereo imaging, providing excellent sound quality,
even when the speakers must be mounted in less-than-
ideal locations.
The SM55’s enclosure has a low-profile domed shape,
ensuring that the speaker’s sound covers as wide an
area as possible. The enclosure is fabricated from a dense
polypropylene material that absorbs vibrations, reducing
resonances and improving sonic clarity. The perforated
aluminum grille and its ABS support frame (which
completely cover the speaker) can be painted to match the
decor in a one-step process that saves time compared to
traditional flanged speakers.
