SF 3C LP

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 a wide frequency range 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 is ideal for small to medium classrooms with lower ceilings and low to medium power requirements.

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 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 152 Plus 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.
