SF 3CT LP
The SF 3CT LP is the 70/100V transformer version of the low-profile 3" ceiling speaker, made for distributed paging and background audio across many zones.
A single 3" paper-cone driver gives 65 Hz to 20 kHz response and 165 deg conical coverage in a back can only 4" deep, fitting shallow plenums. It runs on 70 V / 100 V lines with taps at 16 W, 8 W, 4 W, 2 W and 1 W, plus 8 ohm direct, handling 16 W rms continuous pink noise.
AVSTEK selects transformer taps to balance level across long 70/100V runs and lays out coverage to AVIXA practice, then commissions the line. The 5-year warranty supports dependable, large-area distributed systems.
