5.5 Low frequency transducer
The LF transducer can be removed and reinstalled without removing the baffle.
Removal
1. Follow the removal instructions in “5.2 Front grille” on page
16.
2. Place the speaker on it’s back (or in monitor wedge posi-
tion) so the LF transducer doesn’t fall out after the screws
are removed.
3. Remove 8 screws around the perimeter of the transducer’s
frame.
Note
: Be very careful when removing the screws. The
screwdriver can easily slip and pierce a hole in the surround
or cone of the transducer.
4. Partially lift the transducer out of the speaker assembly.
5. Disconnect the fastons from the transducer’s positive and
negative terminals.
6. Fully remove the transducer from the speaker assembly.
Installation
1. Place the speaker on it’s back (or in monitor wedge posi-
tion).
2. Connect the fastons to the transducer’s positive (green
wire) and negative (green/black wire) terminals.
Important note
: This connection must have high retention force! Crimp new fastons (0.205” or 5.21 mm female,
14–16 AWG, insulated straight ) to the wiring harness if the old ones are weak.
3. Gently lower the LF transducer into the speaker assembly.
4. Fasten the 8 screws that secure the transducer to the baffle in a star pattern.
Note
: Be very careful when installing the screws. The screwdriver can easily slip and pierce a hole in the surround or
cone of the transducer.
