top of the 12" subwoofer using the column
spacers to reach the desired height, as
shown in the picture below.
In order to disassemble the system,
please take care to unplug each module
pulling up the column vertically.
Don't tilt or bend the column speaker.

Loudspeaker wiring
GP12A
Once assembled, the 8x2" GC52
column loudspeaker is directly driven by a
dedicated channel of the amp module of the
active subwoofer: the speaker connector
is implemented in the joint of the column
spacers and no other wiring is necessary.
GP12
The GP12 passive subwoofer and the
loudspeaker column can be driven by
a GP12A active subwoofer or a KGEAR
amplifier like the GA46. Since the speaker
connector is implemented in the column
joint and no other wiring is necessary, once
assembled, the 8x2" GC52 loudspeaker is
directly driven by an internal wiring from
the speakON connectors on the rear panel.
SpeakON A and speakON B are
connected in parallel in order to make the
signal pass through (see picture below).
