AtlasIED 4-inch and 8-inch speaker drivers include dual-cone and transformer-equipped models used in component ceiling systems. These drivers are intended to be paired with compatible baffles, enclosures and bridges rather than selected by diameter alone.
Verify nominal impedance or transformer voltage, wattage/taps, magnet and driver construction, mounting pattern and the existing baffle/backbox before replacing a driver. A 25V, 70.7V and 8-ohm version may share a similar frame size but is not electrically interchangeable.
For retrofit work, matching the original electrical load is as important as matching the physical diameter.

Confirm speaker type, coverage, driver size, transformer voltage/taps or impedance, mounting hardware, environmental exposure and any safety/plenum listing.
Yes. Provide the existing AtlasIED part number when replacing equipment, or send the system voltage/impedance, application, mounting location and project requirements for new designs.
