HALO-CS Subwoofer – Removing the LF drive unit
1. Lie the enclosure on its' feet and remove the three flange head screws securing
the grille with a PoziDrive PZ2 screwdriver. Turn the enclosure over and repeat
for the other side. Turn the enclosure on to its back and gently lift the grille off
and set to one side.
2. Remove the eight M6 socket cap bolts holding the LF drive unit in place using a
5mm Allen bit – ensure to collect the spring washer for each machine screw.
Gently lift the drive unit out of the enclosure – take care as it is heavy! Please
make a note of drive unit polarity for future reinstatement (red cable to positive,
black cable to negative).
3. To reinstate the drive unit, reconnect the cables and carefully seat the drive unit
in the mounting hole. Ensure the bolt holes line up. It is advisable to ensure each
bolt has started in its thread before tightening any. Once the position is correct,
tighten all six bolts until firm.
4. Replace the grille (note the badge should be on the left of the enclosure when
the enclosure is in the flying orientation, which is with the label text the right
way up and the rubber feet pointing upwards !!) and reinstate the six screws.
Note that two of the screws are shorter – these fit the central hole in the grille.
