The Extron 

SI 3C LP

 is a full-range ceiling speaker featuring a 4"  

(10.2 cm) Low Profile metal back can for use in plenum ceilings. The 
low profile speaker is an excellent choice for ceiling installations with 
tight above-the-ceiling tile space issues, such as air handling units 
installed close to the ceiling. The 3" (7.6 cm) full-range driver features 
an incredibly wide frequency response of 75 Hz to 17 kHz, 16 watts 
continuous pink noise and 32 watts continuous program capacity, 
and an extremely wide conical dispersion of 170°.

The SI 3C LP features an exclusive conical baffle that provides a 
wider room coverage pattern, which is important for rooms with low 
ceilings. This design reduces "beaming" of mid and high frequencies 
directly under the speaker. Voice intelligibility is critical for classrooms 
and many other applications, and the SI 3C LP provides excellent 
voice clarity without compromising music reproduction.

The SI 3C LP offers direct 8 ohm operation with overload protection. 
This speaker is ideal for use with our MPA 122 Integrated Mini Power 
Amplifier in small to medium low ceiling installations requiring two to 
four wide dispersion speakers for maximum room coverage.

Four locking arms allow for a fast, secure hard ceiling installation. 
The SI 3C LP includes mounting hardware to facilitate installation in 
a suspended T-bar ceiling. It features a white grille and bezel that can 
be painted to match the architectural elements of the environment.
