MAINTENANCE
If any of the drive units in your TL series cabinet should cease functioning and need a replacement recone or diaphragm, you are advised to remove the faulty unit from the cabinet and send it to a professional service centre authorised to recone and repair Turbosound loudspeakers.
Removal of the low frequency driver(s)
The perforated steel loudspeaker grille is held in place under tension only, fitting into slots at either side of the baffle. There are no screws or other fixings holding the grille in place.
1.Lay the cabinet on its back and, using two small screwdrivers inserted through the mesh of the grille, firmly pull the grille away from the slot at one side of the baffle until it is free. Set the grille aside for later
2.Undo the four screws holding the driver(s) in place and carefully lift it out and away from the cabinet. Make a note of the driver polarity for later reconnection. Disconnect the cables from the drive unit and completely remove the driver from the cabinet.
3.To reinstate the driver(s) simply reverse the above procedure, making sure you observe the correct polarity when reconnecting the cables back into the terminals of the drive units.
