Hf/ Mf & Lf Crossovers - Bowers & Wilkins 704 S2 Series Service – Technical Manual

9. HF/ MF & LF Crossovers
The 704 Series 2 has two Crossovers HF/ MF
Crossover and LF Crossover. We recommend that
the removal process is carried out while the 704
Series 2 is laying on its back to ensure cabinet
safety.
To gain access to the Crossovers you need to
remove both Bass Units. To do this please
follow the 6. Bass Removal process which begins on
Page 20.
Note: Take care when removing the Bass Units so as
not to damage the Gaskets.
With both Bass Units removed and the two sheets
of wadding put to one side you can clearly see both
Crossovers.
•
HF/ MF Crossover (1)
•
LF Crossover (2)
Note: Take note of the cable positions and which
cables go to which Bass Units.
On the LF Crossover the LF Cables are labelled LF1
to LF2. This corresponds to the intended Bass unit.
Bass Unit 1 (LF1) can be found at the top, working down to Bass Unit 2 (LF2) at the Bottom
of the cabinet.
Next you need to remove the Terminal Tray/ Port. To do this please follow the 7. Terminal
Tray/ Port Removal process which begins on Page 22.
Removing the Terminal Tray/ Port allows you to free the Blue, Brown, Red and Black cables
that lead to both Crossovers.
