TO SERVICE THE STUDIO 120c:
Right Woofer or Tweeter: Remove the right grille. Remove the four screws holding the right woofer using a 2.5mm hex key (Allen wrench). If the woofer
will not come out of the cabinet easily, use a dowel or hammer handle inserted into the rear port tube opening to tap the woofer out. If the tweeter needs
service and the horn will not pull out of the cabinet easily, do not use a tool on the protector bars on the front of the horn, as they may break. You will
need to remove the right woofer, reach into the cabinet through the woofer opening and tap the tweeter out of the cabinet. Remove the bar that attaches
the tweeter to the horn using a Phillips screwdriver.
Left Woofer: Remove both grilles. Remove all six grille cups in the front bezel with a needle-nosed pliers or similar tool. Remove all six bezel screws
using a 2.5mm hex key. Remove the bezel by pulling it straight out from the cabinet. Remove the four screws holding the left woofer using a 2.5mm hex
key. If the woofer will not come out of the cabinet easily, remove the right woofer (see above), reach into the cabinet through the woofer opening and
push the left woofer out of the cabinet.
