i-12: Front Low Frequency Drive Units
1. Carefully remove the foam from the grilles – it is held in place with Velcro fasteners. Using a No.2 Pozidrive
screwdriver, undo the Pozidrive screws holding each grille in place, then remove the grilles to gain access to
the drive units.
2. Using a 10mm socket, undo the four M6 Nyloc nuts holding the drive unit in place. Disconnect the cables, and
lift the drive unit clear – ensuring to retain the four nuts, eight washers (shakeproof and flat for each bolt) and
the four speaker clamps for future reinstatement.
3. To reinstate the drive unit, carefully place it into the locating slot, then simply reverse the above procedure.
Please observe the correct (yet unusual) polarity – red cable to negative terminal, black cable to
positive.
4. Reinstate the grille and re-screw in place before sticking the foam back down.
i-12: Rear Low Frequency Drive Units
1. Follow the procedure above to remove the required front drive units – the rear units cannot be removed with
the front units still in place.
2. Using a 3mm Allen key, undo the M5 countersunk machine screws holding the rear door in place. Remove this
door and carefully disconnect the crimp connectors from the spade terminals on the NL4 connectors.
3. Using a 10mm socket, undo the four M6 hex head bolts holding the drive unit in place. Disconnect the cables,
and lift the drive unit clear – ensuring to retain the four bolts, eight washers (shakeproof and flat for each bolt)
and the four speaker clamps for future reinstatement.
4. To reinstate the drive unit, carefully place it into the locating slot, then simply reverse the above procedure.
Please observe the correct polarity – red cable to positive terminal, black cable to negative – and
observe that this is different to the front pair of drive units.
5. Re-attach the crimp connectors to the NL4 spades (red cable to 1+, black cable to 1-) and screw the door back
down again, ensuring that the door sits flush with the rear of the enclosure.
