5 Installation under the oor
The speaker will t between joists with standard
40cm (16in) or greater spacing, such that the visible
louvre straddles the gap between them. A clearance
of 25cm (10in) or greater behind the top of the joists
is required.
The product is not recommended if the oor is to
be covered by a thick carpet. Very short pile carpet,
such as carpet tiles, may be accommodated with
care.
Mark the centre line of the desired louvre position on
the top face of the joists at each side (Figure 28).
Run appropriate gauge speaker cable to the
installation point. Secure it to the joists so it cannot
rattle, with the nal tie point close to the marked
louvre centre line near the bottom of the joist. Leave
approximately 30cm – 50cm (12in - 20in) free at the
end (Figure 29).
Attach the four support brackets to the sides of the
cabinet as shown, using two No.8 x 12mm screws
(h) per bracket. The lateral position of the brackets is
not critical, but ensure they are set ush with the top
surface of the cabinet when the cowl opening faces
upwards.
Lay the speaker between the joists, supported by
the brackets overlapping the joists (Figure 31).
If the joist spacing is too great to allow screwing
through the brackets into the joists, a custom
support method will need to be applied by the
installer.
Align the louvre frame with the marks on the beams,
making sure it is square to the wall and mark the
outline of the brackets on the joists.
Remove the subwoofer and rebate the joists to
a depth of 2mm (0.08 in) to accommodate the
thickness of the brackets (Figure 32).
Screw the support bar (j) to the top of the cowl as
shown using the three No.6 x 25mm (1in) screws (m)
into the pre-drilled pilot holes (Figure 33).
