4.7 The baffle can now be inserted into the back box.
The baffle insertion and attachment technique is slightly
different in the case of the CWM7.3 and CWM7.4/5.
In both cases however you should first ensure that the
connector on the baffle is oriented correctly with the
connector inside the back box. CWM7.3 Baffle Insertion
If the CWM7.3 is to be used in landscape orientation
the MF/HF baffle must be removed and rotated 90°
so the tweeter is uppermost in the installed speaker.
If necessary, this should be done before the baffle is
inserted in the back box.
To rotate the MF/HF baffle first remove the four screws
holding it in place. Now, with your hand gently over
the midrange driver, lean the whole baffle assembly
forward slightly so that the MF/HF baffle begins to fall
out. Do not let it fall completely but return the baffle
to the upright position while holding the MF/HF baffle
out of its rebate. Finally withdraw the MF/HF baffle
completely, turn it 90°, reseat it in the rebate and
replace the four screws. Tighten the screws to a torque
of 1.5Nm. The diagram above illustrates removal and
rotation of the MF/HF baffle.
With the MF/HF baffle in the correct orientation the
baffle assembly can be lifted and inserted in the back
box till it is just sub-flush of the back-box flange. Take
care to ensure that the electrical connector lines up.
The baffle is held in the back box by eight screws.
Tighten the screws to a torque of 1.5Nm. The baffle will
then be secured in the back box.
