Details

Extron CS 123T (part number 42-242-03) — complete full-range SpeedMount ceiling speaker system, pairing a CS 120P plenum enclosure with a CS 3T speaker cartridge.

CS 123T combines Extron's plenum enclosure with a single 3" full-range driver for paging and voice reinforcement where wide, even coverage matters more than bass extension. Because the enclosure and cartridge remain separate parts even when bought together, low-voltage and AV crews can rough in the enclosures on one visit and drop in the driver cartridges on another, without losing plenum compliance.

Key Capabilities

Complete SpeedMount system: CS 120P plenum enclosure plus CS 3T speaker cartridge
3" full-range paper cone driver with 165° conical coverage for wide paging dispersion
16 W continuous pink noise / 32 W continuous program power handling
Six-position rotary taps for 70 V or 100 V lines, or direct 8 ohm operation
Frequency range of 118 Hz to 20 kHz (-10 dB)
UL 2043 listed for plenum airspace use when the CS 3T cartridge is installed in the CS 120P

Where It Is Used

Used for paging and voice announcements in conference rooms, classrooms, and lecture halls where wide coverage and intelligibility matter more than full-range music reproduction.
