For one pick point suspension, the middle hole must be used. For two, use only the outer holes.
Eye-bolts without shoulder are designed for vertical loading only. Conversely, eye-bolts with shoulder
allow lifting from different angles and therefore should be preferred. In any case, the force must always
be applied perpendicular to the axis of the centre of the eye.
Finally, use the hole on the centre flange to string a steel security cable and at-tach an additional fastener
for increased safety.
COVERAGE
ADJUSTMENT
By default, the horn of the CV 212 is placed to have a 90° coverage in the horizontal plane and 60° in the
vertical. This can be easily changed to adapt to applications where a narrower horizontal and/or wider
vertical coverage is needed. To rotate the horn:
1
Remove the front grille
. Remove the seven screws located on each side and pull it out.
2
Release the tweeter-horn assembly
. Remove the four screws around the horn and carefully,
separate it from the cabinet. Take care not to harm the gasket around its inner edges, nor to
disconnect the terminals of the compression driver.
3
Rotate 90° the tweeter-horn assembly
.
4
Place back the tweeter-horn assembly
. After turning it 90° around its front-rear axis, put the horn
again in the cabinet. Make sure the gasket is flat and sealing correctly against the wooden slot.
5
Fasten the tweeter-horn assembly
. Insert and tight partially the four screws of the horn in their
corresponding threads. Fully tighten the four screws in the corners. This order will prevent possible
harm of the plastic part of the horn.
6
Install the grille
. Align the grille on its position and push from the side edges to attach it back.
Insert and tighten the seven screws on each side to fasten it completely.
