Installing the S55i in the Ceiling
The S55i can also be installed above the ceiling, or under the floor, assuming
you have suitable attic or crawl space access. Although the S55i can fit between
standard ceiling or floor joists, we recommend placing the S55i across the joists.
It does not have to be perfectly perpendicular to the joists, but should rest
above (or below) them rather than in between them. This prevents its weight
from being supported by the finished surface of the ceiling (dry-wall, plaster,
etc.).
The S55i should be supported or suspended in a manner that does not subject
it to twisting or torsional forces that would stress the enclosure. No wooden or
metal enclosure should be forced against an irregular surface. If the studs are
appreciably curved or warped in an installation, the installer must insert shims
between the S55i front panel and the stud surfaces to avoid such stresses, as
would be the case for any in-wall loudspeaker.
All the following photos are illustrative of how the speakers would be installed
in an attic space, venting into the room below. (Installing it in the floor is similar,
although you might want to replace the HVAC grille with a grate specifically de-
signed for floor registers.) Note that while the photos are of the Wisdom Audio
S90i, the process is the same for the S55i.
1. Check your hardware kit to ensure it is complete.
The parts required for in-ceiling mounting include:
• Ceiling flange assembly
• S55i flange assembly
• Two band clamps
• HVAC grille (which optionally can be replaced with one that
matches the other grilles used in the home)
