For 2' x 4' ceiling grids, a simple modification and the included support rail are necessary.
- Identify the center of a 2' x 4' ceiling tile where the speaker will be placed.
- Make one cut to the ceiling tile to create a 2' x 2' opening.
- Position the included support rail across the 2' x 4' grid to create a stable edge for the speaker.
- Drop the Bogen CSD2X2 speaker system into the newly created 2' x 2' opening, ensuring it is securely supported by the grid and the support rail.
