1. The

speaker shall have a 

1-watt amplifier. The typical cur-

rent consumption shall be 

1 CU (50 mA). The fre-

quency response shall be 

125 Hz to 15 kHz.

Dispersion angle shall be no less than 

120°.

Sensitivity, measured 

1-watt @ 1 meter on axis, shall

be a minimum of 90 dBspl. Input sensitivity shall be
125 mVrms. Input impedance shall be 2k ohms.
The speaker shall comply with NFPA National Code
160b that allows speakers to be installed in plenums
and other air handling spaces. The speaker shall also
comply with UL-2043 (report available).

The speaker shall be of durable ABS plastic construc-
tion and shall be mounted using specially designed

designed wing nuts shall be used for securing the

speaker to the ceiling tile. Four standard wire nuts
will connect the speaker wires to the studs. One set
of studs shall be used to connect 24V (nominal)
power, and the other set shall be used to connect an
audio signal to the speaker. In each set of studs, color-
coding will be used as a means of designating polari-
ty. Copper-plated studs shall be positive (+) and nick-
el-plated studs shall be negative (-). The speaker shall
include a large, rubber O-ring seal to hold the base
of the speaker cavity tight to the ceiling tile. A tile
bridge support (Model SMTB) shall be available for
distributing the weight of the speaker in suspended
ceilings.

The unit shall measure 9-

1/2" in diameter by 3" in

depth. Base diameter against ceiling shall be 8-3/4".
Product weight shall be 2 lb.
