AtlasIED VTB-6 Environment Resistant Compression Driver With 25V Transformer

The AtlasIED VTB Series targets system integrators and facilities engineers who need dependable audio output in environments where standard loudspeakers fail — industrial plants, correctional facilities, warehouses, and outdoor installations where moisture, corrosion, vibration, and vermin are constant threats. The water-sealed driver and die-cast zinc housing are engineered to survive where conventional cone speakers cannot, making this a purpose-built solution for life-safety and intercom infrastructure rather than general audio distribution.

The integral exponential horn maximizes intelligibility for voice and electronic tone signals, which is the primary demand in paging, intercom, and alarm applications where clarity at the listening position is non-negotiable. The built-in multi-tap transformer allows the VTB Series to integrate directly into 25V distributed audio systems without external transformer hardware, simplifying installation in both new construction and retrofit scenarios. The series supports a range of transformer configurations across its six models, giving integrators the flexibility to match wattage and impedance to system design requirements.

Termination via color-coded leads and compatibility with a variety of standard or custom housings and face plates means the VTB Series adapts to existing enclosure infrastructure rather than demanding proprietary mounting solutions. UL recognition as a speaker component under UL 1480 makes these units suitable for fire alarm and life-safety system integration where listed components are a code requirement. Rated for continuous operation across a wide temperature range, these drivers are equally viable in stationary installed systems and mobile or temporary industrial deployments.
