6 Yarden 4-C Your Yarden 4-C Closed-back Ceiling Speaker
Each Closed-back Ceiling speaker is supported by a C-ring and two tile rails. The tile
rails prevent the speakers from falling if the tile itself comes out or falls apart, as
their ends catch onto the T-grid. When mounting onto the ceiling tiles, use both
supports. When mounting onto a sheetrock ceiling, the C-ring alone is used to
reinforce the ceiling material.
Be sure that the tiles can support the speaker. Smaller sized tiles or
fiberglass-type tiles cannot support the weight of the speakers.
When this is the case, the speakers will need additional support.
