Obviously, there cannot be any plumbing or wiring in this stud bay, nor
firebreaks. The S90i will use virtually all of the available space in a stan-
dard eight foot 2 x 6 stud bay.
2. Stand the S90i in front of the bay in which it will reside; make the elec-
trical connections
There are two methods commonly used for making these connections.
If you have access to the adjacent stud bay, drill a hole through the 2 x 6
stud between where the S90i’s feet will be when it is in place, and feed
the pigtail through the hole. You can then make the connection in the
adjacent stud bay, where you will have plenty of room to work. You can
even put the connections inside a J-box for future serviceability if you so
desire.
Alternatively, sometimes it works out easier to bring the connecting wire
through the top plate or sole plate of the same stud bay in which the S90i
is located. If so, the connection can be made in the space between the
feet at the end of the S90i with the pigtail. If the signal is coming through
the attic and the top plate, the S90i will need to be “upside down” with
its feet at the top of the bay. This places the grille high on the wall, which
may be preferred aesthetically (since it can be mistaken as a surround
speaker).
The preferred method for making the electrical connection is to solder the
wires together and then insulate the connection with shrink tubing. If this
is impractical, use appropriately-sized wire nuts and wrap the wire nut
connections in black electrical tape to prevent any chance of the connec-
tion vibrating loose.
3. Stand the S90i in the stud bay, dress the wires so that they cannot rattle,
and screw the front board to the studs with drywall screws
The S90i has predrilled, countersunk screw holes so standard #8 dry wall
screws will sit with their heads below the surface, so they can be tapes
and spackled without any trace. A total of eighteen (18) dry wall screws
are used.
The S90 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 curved or warped in an installation the installer must insert
shims between the S90 front panel and the stud surfaces to avoid such
stresses, as would be the case for any in-wall loudspeaker.
4. Tape and spackle the seams
5. After everything has been painted, slice the paint along the edge of the
foam plug in the bass vent. Remove and discard the foam.
The foam plug is there simply to protect the inside of the S90i, and partic-
ularly the woofers themselves, from being splattered with paint. Once that
purpose has been served, it needs to be removed. A sharp utility knife can
be used to break any paint that may have leaked into the area.
