MAINTENANCE

If any of the drive units in your Aspect series cabinet should cease functioning and need to be replaced or repaired, you are advised to remove the faulty unit from the cabinet and send it to a professional service centre authorised to repair Turbosound loudspeakers.

This section covers the removal and replacement of the high frequency drivers and the high- mid driver; and also the procedure to rotate the mid/high section from A (horizontal) to B (vertical) mode, or vice versa.

It is easiest to work on the cabinet when it is placed on its back, either on the floor or on a low workbench. The only tools required for maintenance are:

M5 Allen key

M4 Allen key

Two pairs of long nose pliers 13mm ring spanner or socket

The perforated loudspeaker grille and horn assembly are held in place by five M8 countersunk screws on the top, bottom and sides of the cabinet. Locate and undo these screws using a 5mm hex key or power tool if available.
