MAINTENANCE
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.
EMS-215: Low Frequency Drive Units
1.
Using a PZ2 screwdriver, remove the screws securing the grille in place. With the EMS-215, ease the grille out
of its retaining slot. For the EMS-215C, simply lift the grille clear of the enclosure.
2.
Using a 5mm Allen key, remove the six M6 socket-head bolts holding the required drive unit in place, and keep
them safe – ensuring you have collected both the shake-proof and flat washers for each bolt. 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.
For the EMS-215C, eight bolts secure each drive unit in place.
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.
Reposition the front grille (on the EMS-215, ease it into the retaining slot) and reinstate the screws.
