outer lip a bit of a struggle. Care must be taken not to puncture the dust cover
when performing this final installation step. Figure 8.4 shows both bass panels
pushed into place.
After the two bass panels are firmly seated in place, the treble panel can be
centered between the two bass panels. This is done by pushing the center of the
treble panel forward from the rear center , so that it no longer contacts the four
retaining pins on the vertical supports. The panel can then be moved back and
forth to center it between the bass panels. After centered, the panel can be pushed
onto the four retaining pins. This is done by pressing on the front center of the
bass panel dust cover frames which are resting against the treble panel dust cover
frame.
The aluminum retaining brackets can now be screwed in place as seen in fig-
ures 8.5 and 8.6. These brackets hold the panels firmly in place, preventing the
bass panels from slipping off the side rails and also preventing the treble panel
from shifting by not allowing the inside edges of the bass panels to shift forward.
The extra thickness of a rebuilt treble panel and bass panel can make the bottom
bracket difficult to install. However the top bracket should fit into place easily.
The bottom bracket can be screwed in place farther forward in the frame. This
causes the bracket to be tilted due to a lip in the frame. Another solution if the
bracket cannot be made to fit is to bend the front outside corners outward as seen
in figure 8.6.
After the two retaining brackets are installed and screwed in place, the speaker
can be turned around and the panels, input transformer, and power supplies can be
wired. A speaker ready to be wired is shown in figure 8.7.
