5.0 - Servicing Information
Your EM Acoustics loudspeakers have been rigorously tested before they leave our factory, to ensure that they
give you a lifetime of flawless operation. Should any of your drive units fail and need replacing, please follow
the guidelines below.
MSE-218: Low Frequency Drive Unit
1. Using a PZ2 Pozidrive screwdriver, undo the screws securing the front grille in place. Gently remove the
grille from the front of the enclosure.
2. Using a 5mm Allen key, remove the eight M6 socket-head bolts holding the required drive unit in place.
Gently lift the drive unit out of its locating hole – please take care as it is heavy! Carefully disconnect the
cables from the drive unit.
3. To reinstate the driver, simply reverse the above procedure. Please observe the correct polarity – red
cable to positive terminal, black cable to negative.
4. Reinstate the grille by gently placing it in place over the front of the loudspeaker. Replace the PZ2 screws
to secure the grille in place.
