AtlasIED FA42T-6MB 4" Coaxial In-Ceiling Speaker Motorboard Assembly

The FA42T-6MB is engineered for AV integrators working on phased installation projects where enclosures must be deployed and sealed before speakers are available on-site. By sharing the exact footprint and bolt-hole pattern of a standard 6" FA series motorboard, this 4" coaxial assembly drops into any Strategy Series 6" enclosure without adaptation or additional hardware, eliminating costly return visits or field modifications.

Installed audio professionals specifying 70.7V or 100V distributed systems will find the FA42T-6MB well-suited to corporate, hospitality, retail, and institutional environments where consistent coverage and reliable tap selection are non-negotiable. The front-mounted tap selector — supporting 1, 2, 4, 8, and 16-watt settings — allows system tuning adjustments after the enclosure is in place, a practical advantage in acoustically variable spaces. The tuned port is optimized to extend low-frequency response when paired with FA97-6 or FA95-6 enclosures, maintaining intelligibility without subwoofer support in moderate-SPL applications.

UL 1480 listing for general signaling and a 60-month warranty make the FA42T-6MB a defensible specification choice for projects where compliance documentation and long-term serviceability matter. Compared to sourcing a full FAP42T assembly, integrators gain scheduling flexibility while maintaining the same acoustic performance and transformer quality found in the complete unit.
