AtlasIED FA42T-6MB 4" In-Ceiling Coaxial Speaker Motorboard Assembly with 16W 70.7V/100V Transformer

Built for quick retrofits and reliable distributed audio, the AtlasIED FA42T-6MB 4in in-ceiling coaxial speaker motorboard assembly delivers clear paging and background sound where it matters most. This AtlasIED Strategy Series component combines a compact 4in coaxial driver with a 16W 70.7V/100V transformer, providing a turnkey solution for 70V/100V systems used in security, surveillance and monitoring installations. With a 25W RMS capability and 88 dB sensitivity, the FA42T-6MB produces intelligible voice reproduction across a 75 Hz–20 kHz bandwidth while maintaining low visual impact in ceilings.

Technicians and integrators benefit from a complete motorboard that includes the speaker, transformer, selector switch and front plate—allowing fast swaps into standard FA series 6in enclosures without costly enclosure modifications. The durable PEI tweeter material and Strategy Series footprint make it ideal for schools, retail, corporate, and security-centric environments requiring dependable paging and alarm notifications.
