Speaker.
About the SM 3 Speaker
The SM 3 speaker is a low profile surface-mount speaker system that features a three-inch
full-range driver with very wide audio dispersion. Speaker mounting incorporates a separate
mounting plate that can be attached directly to a wall or to an electrical box behind the wall.
The speaker wiring attaches to the mounting plate so that the speaker can easily slide into
the mounting plate, making electrical contact between the plate and the contacts on the
speaker. A built-in locking mechanism between the speaker and the mounting plate also
prevents the speaker from being removed by unauthorized personnel. The speaker may be
easily removed by depressing a hidden release mechanism that does not require tools.
Features
• Concealed mounting system — Exclusive concealed mounting system included with
0° and 10° mounting plates.
• Mounting plate — Each speaker comes with a mounting plate that accommodates
both American (3.25 inches) and European (60 mm) electrical boxes. Two types of
mounting plates are provided with each speaker for both a flat (ADA compliant –
protruding less than four inches off of the wall) and an angled (10°) mounting profile.
• 3-inch driver with paper cone — Full range with a wide audio dispersion.
• Rated power — 15 W continuous pink noise (per IEC 60268-5); 30 W continuous
program.
• Frequency response — 75 Hz to 18 kHz, -10 dB (full space)
• Bass-reflex, UV stabilized, flame retardant PC/ABS plastic enclosure
• Color options — Available in black or white finishes.
• Automatic speaker connection — Recessed gold-plated contact pins integrated into
each speaker automatically make an electrical connection when the speaker is mounted
to the wall mounting plate.
• Hidden release mechanism — The speaker automatically locks on to the
wall mounting adapter to prevent tampering, but a hidden release mechanism allows
the speaker to be quickly unlocked without the use of tools.
• Security key — A special key allows the speaker to be locked or unlocked to the
mounting plate.
